How to Present a Case Study: Examples and Best Practices

Marketers, consultants, salespeople, and all other types of business managers often use case study analysis to highlight a success story, showing how an exciting problem can be or was addressed. But how do you create a compelling case study and then turn it into a memorable presentation? Get a lowdown from this post!

How to write a case study: a 4-step framework, how to do a case study presentation: 3 proven tips, how long should a case study be, final tip: use compelling presentation visuals, business case study examples, what is a case study .

Let’s start with this great case study definition by the University of South Caroline:

In the social sciences, the term case study refers to both a method of analysis and a specific research design for examining a problem, both of which can generalize findings across populations.

In simpler terms — a case study is investigative research into a problem aimed at presenting or highlighting solution(s) to the analyzed issues.

A standard business case study provides insights into:

• General business/market conditions 
• The main problem faced 
• Methods applied 
• The outcomes gained using a specific tool or approach

Case studies (also called case reports) are also used in clinical settings to analyze patient outcomes outside of the business realm. 

But this is a topic for another time. In this post, we’ll focus on teaching you how to write and present a business case, plus share several case study PowerPoint templates and design tips! 

Why Case Studies are a Popular Marketing Technique 

Besides presenting a solution to an internal issue, case studies are often used as a content marketing technique . According to a 2020 Content Marketing Institute report, 69% of B2B marketers use case studies as part of their marketing mix.

A case study informs the reader about a possible solution and soft-sells the results, which can be achieved with your help (e.g., by using your software or by partnering with your specialist). 

For the above purpose, case studies work like a charm. Per the same report: 

• For 9% of marketers, case studies are also the best method for nurturing leads. 
• 23% admit that case studies are beneficial for improving conversions. 

Moreover, case studies also help improve your brand’s credibility, especially in the current fake news landscape and dubious claims made without proper credit. 

Ultimately, case studies naturally help build up more compelling, relatable stories and showcase your product benefits through the prism of extra social proof, courtesy of the case study subject. 

Most case studies come either as a slide deck or as a downloadable PDF document. 

Typically, you have several options to distribute your case study for maximum reach:

• Case study presentations — in-person, virtual, or pre-recorded, there are many times when a case study presentation comes in handy. For example, during client workshops, sales pitches, networking events, conferences, trade shows, etc. 
• Dedicated website page — highlighting case study examples on your website is a great way to convert middle-on-the-funnel prospects. Google’s Think With Google case study section is a great example of a web case study design done right.

• Blog case studies — data-driven storytelling is a staunch way to stand apart from your competition by providing unique insights, no other brand can tell. 
• Video case studies — video is a great medium for showcasing more complex business cases and celebrating customer success stories.

Once you decide on your case study format, the next step is collecting data and then translating it into a storyline. There are different case study methods and research approaches you can use to procure data. 

But let’s say you already have all your facts straight and need to organize them in a clean copy for your presentation deck. Here’s how you should do it. 

1. Identify the Problem 

Every compelling case study research starts with a problem statement definition. While in business settings, there’s no need to explain your methodology in-depth; you should still open your presentation with a quick problem recap slide.

Be sure to mention: 

• What’s the purpose of the case study? What will the audience learn? 
• Set the scene. Explain the before, aka the problems someone was facing. 
• Advertise the main issues and findings without highlighting specific details.

The above information should nicely fit in several paragraphs or 2-3 case study template slides

2. Explain the Solution 

The bulk of your case study copy and presentation slides should focus on the provided solution(s). This is the time to speak at length about how the subject went from before to the glorious after. 

Here are some writing prompts to help you articulate this better:

• State the subject’s main objective and goals. What outcomes were they after?
• Explain the main solution(s) provided. What was done? Why this, but not that? 
• Mention if they tried any alternatives. Why did those work? Why were you better?

This part may take the longest to write. Don’t rush it and reiterate several times. Sprinkle in some powerful words and catchphrases to make your copy more compelling.

3. Collect Testimonials 

Persuasive case studies feature the voice of customer (VoC) data — first-party testimonials and assessments of how well the solution works. These provide extra social proof and credibility to all the claims you are making. 

So plan and schedule interviews with your subjects to collect their input and testimonials. Also, design your case study interview questions in a way that lets you obtain quantifiable results.

4. Package The Information in a Slide Deck

Once you have a rough first draft, try different business case templates and designs to see how these help structure all the available information. 

As a rule of thumb, try to keep one big idea per slide. If you are talking about a solution, first present the general bullet points. Then give each solution a separate slide where you’ll provide more context and perhaps share some quantifiable results.

For example, if you look at case study presentation examples from AWS like this one about Stripe , you’ll notice that the slide deck has few texts and really focuses on the big picture, while the speaker provides extra context.

Your spoken presentation (and public speaking skills ) are equally if not more important than the case study copy and slide deck. To make a strong business case, follow these quick techniques. 

Focus on Telling a Great Story

A case study is a story of overcoming a challenge, and achieving something grand. Your delivery should reflect that. Step away from the standard “features => benefits” sales formula. Instead, make your customer the hero of the study. Describe the road they went through and how you’ve helped them succeed. 

The premises of your story can be as simple as:

• Help with overcoming a hurdle
• Gaining major impact
• Reaching a new milestone
• Solving a persisting issue no one else code 

Based on the above, create a clear story arc. Show where your hero started. Then explain what type of journey they went through. Inject some emotions into the mix to make your narrative more relatable and memorable. 

Experiment with Copywriting Formulas 

Copywriting is the art and science of organizing words into compelling and persuasive combinations that help readers retain the right ideas. 

To ensure that the audience retains the right takeaways from your case study presentation, you can try using some of the classic copywriting formulas to structure your delivery. These include:

• AIDCA — short for A ttention, I nterest, D esire, C onviction, and A ction. First, grab the audience’s attention by addressing the major problem. Next, pique their interest with some teaser facts. Spark their desire by showing that you know the right way out. Then, show a conviction that you know how to solve the issue—finally, prompt follow-up action such as contacting you to learn more. 
• PADS — is short for Problem, Agitation, Discredit, or Solution. This is more of a sales approach to case study narration. Again, you start with a problem, agitate about its importance, discredit why other solutions won’t cut it, and then present your option. 
• 4Ps — short for P roblem, P romise, P roof, P roposal. This is a middle-ground option that prioritizes storytelling over hard pitches. Set the scene first with a problem. Then make a promise of how you can solve it. Show proof in the form of numbers, testimonials, and different scenarios. Round it up with a proposal for getting the same outcomes. 

Take an Emotion-Inducing Perspective

The key to building a strong rapport with an audience is showing that you are one of them and fully understand what they are going through. 

One of the ways to build this connection is by speaking from an emotion-inducing perspective. This is best illustrated with an example: 

• A business owner went to the bank
• A business owner came into a bank branch 

In the second case, the wording prompts listeners to paint a mental picture from the perspective of the bank employees — a role you’d like them to relate to. By placing your audience in the right visual perspective, you can make them more receptive to your pitches. 

One common question that arises when creating a case study is determining its length. The length of a case study can vary depending on the complexity of the problem and the level of detail you want to provide. Here are some general guidelines to help you decide how long your case study should be:

• Concise and Informative: A good case study should be concise and to the point. Avoid unnecessary fluff and filler content. Focus on providing valuable information and insights.
• Tailor to Your Audience: Consider your target audience when deciding the length. If you’re presenting to a technical audience, you might include more in-depth technical details. For a non-technical audience, keep it more high-level and accessible.
• Cover Key Points: Ensure that your case study covers the key points effectively. These include the problem statement, the solution, and the outcomes. Provide enough information for the reader to understand the context and the significance of your case.
• Visuals: Visual elements such as charts, graphs, images, and diagrams can help convey information more effectively. Use visuals to supplement your written content and make complex information easier to understand.
• Engagement: Keep your audience engaged. A case study that is too long may lose the reader’s interest. Make sure the content is engaging and holds the reader’s attention throughout.
• Consider the Format: Depending on the format you choose (e.g., written document, presentation, video), the ideal length may vary. For written case studies, aim for a length that can be easily read in one sitting.

In general, a written case study for business purposes often falls in the range of 1,000 to 2,000 words. However, this is not a strict rule, and the length can be shorter or longer based on the factors mentioned above.

Our brain is wired to process images much faster than text. So when you are presenting a case study, always look for an opportunity to tie in some illustrations such as: 

• A product demo/preview
• Processes chart 
• Call-out quotes or numbers
• Custom illustrations or graphics 
• Customer or team headshots 

Use icons to minimize the volume of text. Also, opt for readable fonts that can look good in a smaller size too.

To better understand how to create an effective business case study, let’s explore some examples of successful case studies:

Apple Inc.: Apple’s case study on the launch of the iPhone is a classic example. It covers the problem of a changing mobile phone market, the innovative solution (the iPhone), and the outstanding outcomes, such as market dominance and increased revenue.

Tesla, Inc.: Tesla’s case study on electric vehicles and sustainable transportation is another compelling example. It addresses the problem of environmental concerns and the need for sustainable transportation solutions. The case study highlights Tesla’s electric cars as the solution and showcases the positive impact on reducing carbon emissions.

Amazon.com: Amazon’s case study on customer-centricity is a great illustration of how the company transformed the e-commerce industry. It discusses the problem of customer dissatisfaction with traditional retail, Amazon’s customer-focused approach as the solution, and the remarkable outcomes in terms of customer loyalty and market growth.

Coca-Cola: Coca-Cola’s case study on brand evolution is a valuable example. It outlines the challenge of adapting to changing consumer preferences and demographics. The case study demonstrates how Coca-Cola continually reinvented its brand to stay relevant and succeed in the global market.

Airbnb: Airbnb’s case study on the sharing economy is an intriguing example. It addresses the problem of travelers seeking unique and affordable accommodations. The case study presents Airbnb’s platform as the solution and highlights its impact on the hospitality industry and the sharing economy.

These examples showcase the diversity of case studies in the business world and how they effectively communicate problems, solutions, and outcomes. When creating your own business case study, use these examples as inspiration and tailor your approach to your specific industry and target audience.

Finally, practice your case study presentation several times — solo and together with your team — to collect feedback and make last-minute refinements!

Case Study – Methods, Examples and Guide

Table of Contents

A case study is a research method that involves an in-depth examination and analysis of a particular phenomenon or case, such as an individual, organization, community, event, or situation.

It is a qualitative research approach that aims to provide a detailed and comprehensive understanding of the case being studied. Case studies typically involve multiple sources of data, including interviews, observations, documents, and artifacts, which are analyzed using various techniques, such as content analysis, thematic analysis, and grounded theory. The findings of a case study are often used to develop theories, inform policy or practice, or generate new research questions.

Types of Case Study

Types and Methods of Case Study are as follows:

Single-Case Study

A single-case study is an in-depth analysis of a single case. This type of case study is useful when the researcher wants to understand a specific phenomenon in detail.

For Example , A researcher might conduct a single-case study on a particular individual to understand their experiences with a particular health condition or a specific organization to explore their management practices. The researcher collects data from multiple sources, such as interviews, observations, and documents, and uses various techniques to analyze the data, such as content analysis or thematic analysis. The findings of a single-case study are often used to generate new research questions, develop theories, or inform policy or practice.

Multiple-Case Study

A multiple-case study involves the analysis of several cases that are similar in nature. This type of case study is useful when the researcher wants to identify similarities and differences between the cases.

For Example, a researcher might conduct a multiple-case study on several companies to explore the factors that contribute to their success or failure. The researcher collects data from each case, compares and contrasts the findings, and uses various techniques to analyze the data, such as comparative analysis or pattern-matching. The findings of a multiple-case study can be used to develop theories, inform policy or practice, or generate new research questions.

Exploratory Case Study

An exploratory case study is used to explore a new or understudied phenomenon. This type of case study is useful when the researcher wants to generate hypotheses or theories about the phenomenon.

For Example, a researcher might conduct an exploratory case study on a new technology to understand its potential impact on society. The researcher collects data from multiple sources, such as interviews, observations, and documents, and uses various techniques to analyze the data, such as grounded theory or content analysis. The findings of an exploratory case study can be used to generate new research questions, develop theories, or inform policy or practice.

Descriptive Case Study

A descriptive case study is used to describe a particular phenomenon in detail. This type of case study is useful when the researcher wants to provide a comprehensive account of the phenomenon.

For Example, a researcher might conduct a descriptive case study on a particular community to understand its social and economic characteristics. The researcher collects data from multiple sources, such as interviews, observations, and documents, and uses various techniques to analyze the data, such as content analysis or thematic analysis. The findings of a descriptive case study can be used to inform policy or practice or generate new research questions.

Instrumental Case Study

An instrumental case study is used to understand a particular phenomenon that is instrumental in achieving a particular goal. This type of case study is useful when the researcher wants to understand the role of the phenomenon in achieving the goal.

For Example, a researcher might conduct an instrumental case study on a particular policy to understand its impact on achieving a particular goal, such as reducing poverty. The researcher collects data from multiple sources, such as interviews, observations, and documents, and uses various techniques to analyze the data, such as content analysis or thematic analysis. The findings of an instrumental case study can be used to inform policy or practice or generate new research questions.

Case Study Data Collection Methods

Here are some common data collection methods for case studies:

Interviews involve asking questions to individuals who have knowledge or experience relevant to the case study. Interviews can be structured (where the same questions are asked to all participants) or unstructured (where the interviewer follows up on the responses with further questions). Interviews can be conducted in person, over the phone, or through video conferencing.

Observations

Observations involve watching and recording the behavior and activities of individuals or groups relevant to the case study. Observations can be participant (where the researcher actively participates in the activities) or non-participant (where the researcher observes from a distance). Observations can be recorded using notes, audio or video recordings, or photographs.

Documents can be used as a source of information for case studies. Documents can include reports, memos, emails, letters, and other written materials related to the case study. Documents can be collected from the case study participants or from public sources.

Surveys involve asking a set of questions to a sample of individuals relevant to the case study. Surveys can be administered in person, over the phone, through mail or email, or online. Surveys can be used to gather information on attitudes, opinions, or behaviors related to the case study.

Artifacts are physical objects relevant to the case study. Artifacts can include tools, equipment, products, or other objects that provide insights into the case study phenomenon.

How to conduct Case Study Research

Conducting a case study research involves several steps that need to be followed to ensure the quality and rigor of the study. Here are the steps to conduct case study research:

• Define the research questions: The first step in conducting a case study research is to define the research questions. The research questions should be specific, measurable, and relevant to the case study phenomenon under investigation.
• Select the case: The next step is to select the case or cases to be studied. The case should be relevant to the research questions and should provide rich and diverse data that can be used to answer the research questions.
• Collect data: Data can be collected using various methods, such as interviews, observations, documents, surveys, and artifacts. The data collection method should be selected based on the research questions and the nature of the case study phenomenon.
• Analyze the data: The data collected from the case study should be analyzed using various techniques, such as content analysis, thematic analysis, or grounded theory. The analysis should be guided by the research questions and should aim to provide insights and conclusions relevant to the research questions.
• Draw conclusions: The conclusions drawn from the case study should be based on the data analysis and should be relevant to the research questions. The conclusions should be supported by evidence and should be clearly stated.
• Validate the findings: The findings of the case study should be validated by reviewing the data and the analysis with participants or other experts in the field. This helps to ensure the validity and reliability of the findings.
• Write the report: The final step is to write the report of the case study research. The report should provide a clear description of the case study phenomenon, the research questions, the data collection methods, the data analysis, the findings, and the conclusions. The report should be written in a clear and concise manner and should follow the guidelines for academic writing.

Examples of Case Study

Here are some examples of case study research:

• The Hawthorne Studies : Conducted between 1924 and 1932, the Hawthorne Studies were a series of case studies conducted by Elton Mayo and his colleagues to examine the impact of work environment on employee productivity. The studies were conducted at the Hawthorne Works plant of the Western Electric Company in Chicago and included interviews, observations, and experiments.
• The Stanford Prison Experiment: Conducted in 1971, the Stanford Prison Experiment was a case study conducted by Philip Zimbardo to examine the psychological effects of power and authority. The study involved simulating a prison environment and assigning participants to the role of guards or prisoners. The study was controversial due to the ethical issues it raised.
• The Challenger Disaster: The Challenger Disaster was a case study conducted to examine the causes of the Space Shuttle Challenger explosion in 1986. The study included interviews, observations, and analysis of data to identify the technical, organizational, and cultural factors that contributed to the disaster.
• The Enron Scandal: The Enron Scandal was a case study conducted to examine the causes of the Enron Corporation’s bankruptcy in 2001. The study included interviews, analysis of financial data, and review of documents to identify the accounting practices, corporate culture, and ethical issues that led to the company’s downfall.
• The Fukushima Nuclear Disaster : The Fukushima Nuclear Disaster was a case study conducted to examine the causes of the nuclear accident that occurred at the Fukushima Daiichi Nuclear Power Plant in Japan in 2011. The study included interviews, analysis of data, and review of documents to identify the technical, organizational, and cultural factors that contributed to the disaster.

Application of Case Study

Case studies have a wide range of applications across various fields and industries. Here are some examples:

Business and Management

Case studies are widely used in business and management to examine real-life situations and develop problem-solving skills. Case studies can help students and professionals to develop a deep understanding of business concepts, theories, and best practices.

Case studies are used in healthcare to examine patient care, treatment options, and outcomes. Case studies can help healthcare professionals to develop critical thinking skills, diagnose complex medical conditions, and develop effective treatment plans.

Case studies are used in education to examine teaching and learning practices. Case studies can help educators to develop effective teaching strategies, evaluate student progress, and identify areas for improvement.

Social Sciences

Case studies are widely used in social sciences to examine human behavior, social phenomena, and cultural practices. Case studies can help researchers to develop theories, test hypotheses, and gain insights into complex social issues.

Law and Ethics

Case studies are used in law and ethics to examine legal and ethical dilemmas. Case studies can help lawyers, policymakers, and ethical professionals to develop critical thinking skills, analyze complex cases, and make informed decisions.

Purpose of Case Study

The purpose of a case study is to provide a detailed analysis of a specific phenomenon, issue, or problem in its real-life context. A case study is a qualitative research method that involves the in-depth exploration and analysis of a particular case, which can be an individual, group, organization, event, or community.

The primary purpose of a case study is to generate a comprehensive and nuanced understanding of the case, including its history, context, and dynamics. Case studies can help researchers to identify and examine the underlying factors, processes, and mechanisms that contribute to the case and its outcomes. This can help to develop a more accurate and detailed understanding of the case, which can inform future research, practice, or policy.

Case studies can also serve other purposes, including:

• Illustrating a theory or concept: Case studies can be used to illustrate and explain theoretical concepts and frameworks, providing concrete examples of how they can be applied in real-life situations.
• Developing hypotheses: Case studies can help to generate hypotheses about the causal relationships between different factors and outcomes, which can be tested through further research.
• Providing insight into complex issues: Case studies can provide insights into complex and multifaceted issues, which may be difficult to understand through other research methods.
• Informing practice or policy: Case studies can be used to inform practice or policy by identifying best practices, lessons learned, or areas for improvement.

Advantages of Case Study Research

There are several advantages of case study research, including:

• In-depth exploration: Case study research allows for a detailed exploration and analysis of a specific phenomenon, issue, or problem in its real-life context. This can provide a comprehensive understanding of the case and its dynamics, which may not be possible through other research methods.
• Rich data: Case study research can generate rich and detailed data, including qualitative data such as interviews, observations, and documents. This can provide a nuanced understanding of the case and its complexity.
• Holistic perspective: Case study research allows for a holistic perspective of the case, taking into account the various factors, processes, and mechanisms that contribute to the case and its outcomes. This can help to develop a more accurate and comprehensive understanding of the case.
• Theory development: Case study research can help to develop and refine theories and concepts by providing empirical evidence and concrete examples of how they can be applied in real-life situations.
• Practical application: Case study research can inform practice or policy by identifying best practices, lessons learned, or areas for improvement.
• Contextualization: Case study research takes into account the specific context in which the case is situated, which can help to understand how the case is influenced by the social, cultural, and historical factors of its environment.

Limitations of Case Study Research

There are several limitations of case study research, including:

• Limited generalizability : Case studies are typically focused on a single case or a small number of cases, which limits the generalizability of the findings. The unique characteristics of the case may not be applicable to other contexts or populations, which may limit the external validity of the research.
• Biased sampling: Case studies may rely on purposive or convenience sampling, which can introduce bias into the sample selection process. This may limit the representativeness of the sample and the generalizability of the findings.
• Subjectivity: Case studies rely on the interpretation of the researcher, which can introduce subjectivity into the analysis. The researcher’s own biases, assumptions, and perspectives may influence the findings, which may limit the objectivity of the research.
• Limited control: Case studies are typically conducted in naturalistic settings, which limits the control that the researcher has over the environment and the variables being studied. This may limit the ability to establish causal relationships between variables.
• Time-consuming: Case studies can be time-consuming to conduct, as they typically involve a detailed exploration and analysis of a specific case. This may limit the feasibility of conducting multiple case studies or conducting case studies in a timely manner.
• Resource-intensive: Case studies may require significant resources, including time, funding, and expertise. This may limit the ability of researchers to conduct case studies in resource-constrained settings.

A case study presentation involves a comprehensive examination of a specific subject, which could range from an individual, group, location, event, organization or phenomenon.

They’re like puzzles you get to solve with the audience, all while making you think outside the box.

Unlike a basic report or whitepaper, the purpose of a case study presentation is to stimulate critical thinking among the viewers. 

The primary objective of a case study is to provide an extensive and profound comprehension of the chosen topic. You don’t just throw numbers at your audience. You use examples and real-life cases to make you think and see things from different angles.

The primary purpose of presenting a case study is to offer a comprehensive, evidence-based argument that informs, persuades and engages your audience.

Here’s the juicy part: presenting that case study can be your secret weapon. Whether you’re pitching a groundbreaking idea to a room full of suits or trying to impress your professor with your A-game, a well-crafted case study can be the magic dust that sprinkles brilliance over your words.

Think of it like digging into a puzzle you can’t quite crack . A case study lets you explore every piece, turn it over and see how it fits together. This close-up look helps you understand the whole picture, not just a blurry snapshot.

It’s also your chance to showcase how you analyze things, step by step, until you reach a conclusion. It’s all about being open and honest about how you got there.

Besides, presenting a case study gives you an opportunity to connect data and real-world scenarios in a compelling narrative. It helps to make your argument more relatable and accessible, increasing its impact on your audience.

One of the contexts where case studies can be very helpful is during the job interview. In some job interviews, you as candidates may be asked to present a case study as part of the selection process.

Having a case study presentation prepared allows the candidate to demonstrate their ability to understand complex issues, formulate strategies and communicate their ideas effectively.

The way you present a case study can make all the difference in how it’s received. A well-structured presentation not only holds the attention of your audience but also ensures that your key points are communicated clearly and effectively.

In this section, let’s go through the key steps that’ll help you structure your case study presentation for maximum impact.

Let’s get into it. 

Open with an introductory overview 

Start by introducing the subject of your case study and its relevance. Explain why this case study is important and who would benefit from the insights gained. This is your opportunity to grab your audience’s attention.

Explain the problem in question

Dive into the problem or challenge that the case study focuses on. Provide enough background information for the audience to understand the issue. If possible, quantify the problem using data or metrics to show the magnitude or severity.

Detail the solutions to solve the problem

After outlining the problem, describe the steps taken to find a solution. This could include the methodology, any experiments or tests performed and the options that were considered. Make sure to elaborate on why the final solution was chosen over the others.

Key stakeholders Involved

Talk about the individuals, groups or organizations that were directly impacted by or involved in the problem and its solution. 

Stakeholders may experience a range of outcomes—some may benefit, while others could face setbacks.

For example, in a business transformation case study, employees could face job relocations or changes in work culture, while shareholders might be looking at potential gains or losses.

Discuss the key results & outcomes

Discuss the results of implementing the solution. Use data and metrics to back up your statements. Did the solution meet its objectives? What impact did it have on the stakeholders? Be honest about any setbacks or areas for improvement as well.

Include visuals to support your analysis

Visual aids can be incredibly effective in helping your audience grasp complex issues. Utilize charts, graphs, images or video clips to supplement your points. Make sure to explain each visual and how it contributes to your overall argument.

Pie charts illustrate the proportion of different components within a whole, useful for visualizing market share, budget allocation or user demographics.

This is particularly useful especially if you’re displaying survey results in your case study presentation.

Stacked charts on the other hand are perfect for visualizing composition and trends. This is great for analyzing things like customer demographics, product breakdowns or budget allocation in your case study.

Consider this example of a stacked bar chart template. It provides a straightforward summary of the top-selling cake flavors across various locations, offering a quick and comprehensive view of the data.

Recommendations and next steps

Wrap up by providing recommendations based on the case study findings. Outline the next steps that stakeholders should take to either expand on the success of the project or address any remaining challenges.

Acknowledgments and references

Thank the people who contributed to the case study and helped in the problem-solving process. Cite any external resources, reports or data sets that contributed to your analysis.

Feedback & Q&A session

Open the floor for questions and feedback from your audience. This allows for further discussion and can provide additional insights that may not have been considered previously.

Closing remarks

Conclude the presentation by summarizing the key points and emphasizing the takeaways. Thank your audience for their time and participation and express your willingness to engage in further discussions or collaborations on the subject.

Well, the length of a case study presentation can vary depending on the complexity of the topic and the needs of your audience. However, a typical business or academic presentation often lasts between 15 to 30 minutes. 

This time frame usually allows for a thorough explanation of the case while maintaining audience engagement. However, always consider leaving a few minutes at the end for a Q&A session to address any questions or clarify points made during the presentation.

When it comes to presenting a compelling case study, having a well-structured template can be a game-changer. 

It helps you organize your thoughts, data and findings in a coherent and visually pleasing manner. 

Not all case studies are created equal and different scenarios require distinct approaches for maximum impact. 

To save you time and effort, I have curated a list of 5 versatile case study presentation templates, each designed for specific needs and audiences. 

Here are some best case study presentation examples that showcase effective strategies for engaging your audience and conveying complex information clearly.

Nailed your case study, but want to make your presentation even stronger? Avoid these common mistakes to ensure your audience gets the most out of it:

Overloading with information

A case study is not an encyclopedia. Overloading your presentation with excessive data, text or jargon can make it cumbersome and difficult for the audience to digest the key points. Stick to what’s essential and impactful. Need help making your data clear and impactful? Our data presentation templates can help! Find clear and engaging visuals to showcase your findings.

Lack of structure

Jumping haphazardly between points or topics can confuse your audience. A well-structured presentation, with a logical flow from introduction to conclusion, is crucial for effective communication.

Ignoring the audience

Different audiences have different needs and levels of understanding. Failing to adapt your presentation to your audience can result in a disconnect and a less impactful presentation.

Poor visual elements

While content is king, poor design or lack of visual elements can make your case study dull or hard to follow. Make sure you use high-quality images, graphs and other visual aids to support your narrative.

Not focusing on results

A case study aims to showcase a problem and its solution, but what most people care about are the results. Failing to highlight or adequately explain the outcomes can make your presentation fall flat.

How to start a case study presentation?

Starting a case study presentation effectively involves a few key steps:

• Grab attention : Open with a hook—an intriguing statistic, a provocative question or a compelling visual—to engage your audience from the get-go.
• Set the stage : Briefly introduce the subject, context and relevance of the case study to give your audience an idea of what to expect.
• Outline objectives : Clearly state what the case study aims to achieve. Are you solving a problem, proving a point or showcasing a success?
• Agenda : Give a quick outline of the key sections or topics you’ll cover to help the audience follow along.
• Set expectations : Let your audience know what you want them to take away from the presentation, whether it’s knowledge, inspiration or a call to action.

How to present a case study on PowerPoint and on Google Slides?

Presenting a case study on PowerPoint and Google Slides involves a structured approach for clarity and impact using presentation slides :

• Title slide : Start with a title slide that includes the name of the case study, your name and any relevant institutional affiliations.
• Introduction : Follow with a slide that outlines the problem or situation your case study addresses. Include a hook to engage the audience.
• Objectives : Clearly state the goals of the case study in a dedicated slide.
• Findings : Use charts, graphs and bullet points to present your findings succinctly.
• Analysis : Discuss what the findings mean, drawing on supporting data or secondary research as necessary.
• Conclusion : Summarize key takeaways and results.
• Q&A : End with a slide inviting questions from the audience.

What’s the role of analysis in a case study presentation?

The role of analysis in a case study presentation is to interpret the data and findings, providing context and meaning to them. 

It helps your audience understand the implications of the case study, connects the dots between the problem and the solution and may offer recommendations for future action.

Is it important to include real data and results in the presentation?

Yes, including real data and results in a case study presentation is crucial to show experience,  credibility and impact. Authentic data lends weight to your findings and conclusions, enabling the audience to trust your analysis and take your recommendations more seriously

How do I conclude a case study presentation effectively?

To conclude a case study presentation effectively, summarize the key findings, insights and recommendations in a clear and concise manner. 

End with a strong call-to-action or a thought-provoking question to leave a lasting impression on your audience.

What’s the best way to showcase data in a case study presentation ?

The best way to showcase data in a case study presentation is through visual aids like charts, graphs and infographics which make complex information easily digestible, engaging and creative. 

Don’t just report results, visualize them! This template for example lets you transform your social media case study into a captivating infographic that sparks conversation.

Keep the design consistent and simple, avoiding clutter or overly complex visuals that could distract from the message.

Choose a template that perfectly suits your case study where you can utilize different visual aids for maximum impact.

Craft a Killer Marketing Case Study in 5 Steps (Best Templates Included)

Hanisha Kapoor

Why should customers believe in your brand? Sure, testimonials work great. But is this sufficient for them to trust your product?

Consumers have become numb to bold claims, glorious copies, and overdone videos. They want to see if your product or service delivers valuable results or not. 

Thus, you need a concrete marketing case study to present valuable data for converting leads. Marketing case studies help demonstrate how you tackle a problem and provide a solution. It helps you highlight your products as the optimal solution for the customers, thereby creating authority for your company and gaining the trust of the audience.

This is the big-picture value of a marketing case study. Let us delve deeper and narrow our focus on the importance of case studies in business.

Reasons Why Case Studies Matter

• Niche-specific: Case studies are niche-specific and targeted by nature. They zoom in on a particular goal related to your product offering. As a result, they resonate with your target market.
• Problem and solution-centric: Case studies explain how problems are solved. Most people are looking for an optimal solution to their problems and the reason behind the solution. So, case studies serve as the foundation for the “why”.
• Support social proof : Case studies backed with customer reviews work as a proof for the audience that your solution is good. Consumers research and gather information on products they want to purchase. Thus, a well-structured case study positively influences a customer’s buying decision.

Key Components of an Effective Marketing Case Study

Below are the three essential elements that should be considered before putting together or revamping a case study:

• The Problem: The strongest appeal of a marketing case study is that it addresses real-life issues. Thus, emphasize the core problem relevant to your target audience, industry or segment to leave an immediate impact on the customers and establish trust.
• The Solution: This element builds the case for the sponsored product or service. The ideal way to tackle this section of the case study would be to include several solutions available in the industry. Explain how they are incompetent and not meeting the needs of the audience. It will help you introduce your solution and promote its credibility.
• The Results : This is the part of the case study where you shine. Align your case study to specific problems with results to show your audience that you have successfully resolved their issues.

Give your customers a glimpse into what they can potentially achieve from partnering with your company.

These are the essential components of a marketing case study. However, how to create a marketing case study of your own?

Let us walk you through some steps to help you design a case study. We have also included some actionable PowerPoint templates which you can incorporate in your case study to outshine your competition.

Let’s begin!

Choose a case study that caters to your target audience : Companies publish numerous case studies. It is because each case study targets a different segment. For example, a case study about traditional apparel won’t interest someone shopping for resort wear. Therefore, decide on the target audience and create a solid marketing case study for them.

Can machines compete with humans in transcribing audio? A case study using sermons from U.S. religious services

A 2019 Pew Research Center study and follow-up study in 2020 involved the complicated task of transcribing more than 60,000 audio and video files of sermons delivered during religious services at churches around the United States. The primary goal of this research was to evaluate relatively broad topics discussed in the sermons to determine if there were any notable patterns or denominational differences in their length and subject matter.

The huge number of audio and video files meant that it would have been too time-consuming and expensive to ask humans to transcribe all the sermons. Instead, we used Amazon Transcribe , a speech recognition service offered by Amazon Web Services (AWS). We hoped to identify the key themes in the sermons we collected, even if the machine transcriptions were not perfect or at times lacked elements like punctuation that would often come with a traditional human transcription service.

Overall, the machine transcriptions were legible. But we did run into a few challenges. The Amazon service did not always get specific religious terminology or names right. (A few examples included “punches pilot” instead of “Pontius Pilate” and “do Toronto me” in lieu of “Deuteronomy.”) There were also some recordings for which the machine transcription was simply of low quality across the board.

A notable body of research has found that machine transcription sometimes struggles with certain accents or dialects , like regional Southern accents and African American English (AAE). This led us to wonder if the errors we were seeing in the machine transcripts of sermons was coincidental, or if we were encountering performance biases that could be making some transcriptions more reliable than others in a way that might affect the conclusions of our research.

Since we downloaded our sermon files directly as audio or audio/video, we lacked an original written transcript to compare against the machine-transcribed text. Instead, as a test, we asked a third-party human transcription service to tackle portions of some of the sermons that Amazon Transcribe had already transcribed and then compared the results between the two.

What we did

For this experiment, we were interested in using sermons that included a variety of regional accents and dialects among the speakers. One obvious challenge, however, was that we didn’t know much about the speakers themselves. We knew the location of the church where the sermon was delivered, as well as its religious tradition, but these were not necessarily sufficient to assign an accent or a dialect to the person speaking in a recording. We could only use these features as approximations.

With that caveat in mind, we focused the analysis on audio files from the four main religious traditions for which we had a reportable sample size: mainline Protestant, evangelical Protestant, historically Black Protestant and Catholic. We also examined three large geographic regions: the Midwest, the South and a combined region that merges the Northeast and the West (again to account small sample sizes in those two regions).

We took a stratified random sample of 200 sermons from churches for each combination of religious tradition and region, proportional to the number of sermons each church had in the dataset. From this sample of full audio files, we took one random snippet of audio with a duration of 30 to 210 seconds from each file and sent those audio snippets to our external human transcription service. This service was a standard online provider that claimed to have native language speakers, a multistep quality check process and experience transcribing religious content, including sermons specifically. At the end of this process, we had a total sample size of 2,387 texts with both machine and human transcriptions.

How we compared transcriptions

There are a variety of computational methods to measure the similarity or difference between two sets of text. In this analysis, we used a metric known as Levenshtein distance to compare our machine and human transcriptions.

Levenshtein distance counts the number of discrete edits – insertions, deletions and substitutions – at the character level necessary to transform one text string into another. For example, if the word “COVID” is transcribed as “cove in,” there is a Levenshtein distance of three, as the transformation requires three edits: one edit to add a space between the “v” and the “i,” one edit to add an “e” after the “v,” and one edit to substitute the “d” for an “n.”

Levenshtein distance is useful as a comparison metric because it can be normalized and used to compare texts of different lengths. It also allows for nuance by focusing on character-level edits rather than entire words, providing more granularity than something like simple word error rate by scoring how incorrect a mistranscription is.

As a final bit of housekeeping, we standardized both our machine and human transcriptions to make sure that they matched one another stylistically. We transformed all the text into lower case, spelled out numbers and symbols when appropriate, and removed punctuation, filler words and words associated with vocalizations (such as “uh” or “ooh”). We also removed the “[UNINTELLIGIBLE]” annotations that the human transcription service included at our request to flag cases in which someone was speaking but their words couldn’t be clearly understood.

Across all the audio files we evaluated, the average difference between machine transcriptions and human transcriptions was around 11 characters per 100. That is, for every 100 characters in a transcription text, approximately 11 differed from one transcription method to the other.

We were also interested in looking at the difference across religious traditions and geographical regions. To do so, we used pairwise t-tests to test for differences in means across all religious traditions and all regions. (We did not calculate comparisons between each religious tradition and region combination after determining the interaction of the two variables was not statistically significant.)

The analysis found a small but statistically significant difference in Levenshtein distances between machine and human transcriptions for several religious traditions. Text taken from Catholic sermons, for example, had more inconsistency between transcripts than was true of those taken from evangelical Protestant sermons. And sermons from historically Black Protestant churches had significantly more inconsistency in transcriptions when compared with the other religious traditions.

While these differences were statistically significant, their magnitude was relatively small. Even for historically Black Protestant sermons – the tradition with the largest mismatch between machines and humans – the differences worked out to around just 15 characters per 100, or four more than the overall average. It’s also important to remember that we cannot assume the speaker is speaking AAE simply because the sermon was given in a historically Black Protestant church.

One expectation we had going into this experiment is that machine transcription would perform worst with Southern accents. However, we found that transcriptions of sermons from churches in the Midwest had significantly more inconsistency between machine and human transcriptions than those in other regions. Anecdotally, it appears this discrepancy may be because human transcribers had more difficulty than machines in understanding speakers in the Midwest: Sermon texts from the Midwest that were transcribed by humans included a greater number of “[UNINTELLIGIBLE]” annotations than those from other regions. There may also be other factors affecting transcription quality that we cannot account for, such as the possibility that sermons from the Midwest had systematically worse audio quality than those from other regions.

Again, although these differences were statistically significant, their magnitude was relatively small. Midwestern sermons, despite having the greatest inconsistency across regions, had only two more character differences per 100 characters than the overall average.

Conclusions and suggestions

In social science research, automated transcription services have become a popular alternative to human transcription because of the costs and labor involved in the latter. All in all, we found that the machine transcriptions and the human transcriptions used in this experiment were comparable enough to justify our decision to use an automated service in our research on U.S. sermons.

However, our experience does suggest a few ideas that researchers should keep in mind should they find themselves in a similar situation.

First, issues with transcription quality can be tied to the quality of the audio being transcribed – which presents challenges for humans and computers alike. By the same token, machine transcription may perform worse or better on certain accents or dialects – but that’s also true for human transcribers.  When working with audio that has specialized vocabulary (in our case, religious terms), human transcribers sometimes made errors where machines did not. This is likely because a robust machine transcription service will have a larger dictionary of familiar terms than the average person. Similarly, we found that humans are more likely to make typos, something one will not run into with machine transcription.

More generally, reliability is usually an advantage of machine transcription. Human transcription can vary in quality based on the service used, and possibly from one transcript to another if there are multiple human transcribers. But the reliability of machine transcription can sometimes backfire. When presented with a segment of tricky audio, for example, humans can determine that the text is “unintelligible.” A machine, on the other hand, will try to match the sounds it hears as closely as possible to a word it knows with little to no regard for grammar or intelligibility. While this might produce a phonetically similar transcription, it may deviate far from what the speaker truly said.

Ultimately, both machine and human transcription services can be viable options. Beyond the obvious questions of budget and timeline that are often primary considerations, we would suggest evaluating the nature of the audio files that are being analyzed before transcription begins. Audio of mixed quality, or which features competing sound from an audience, can be tricky for humans and machines alike.

Researchers should also determine how important it is to have formatting and punctuation in the text they hope to analyze. Our researchers found that the lack of these elements can be a key barrier to understanding the meaning of a particular piece of text quickly. In our case, it wasn’t an insurmountable barrier, but it certainly added a significant cognitive burden to tasks like labeling training data. And it might have posed an even bigger problem had our analysis relied more heavily on unguided methods for identifying our topics of interest.

Evidence Review of the Adverse Effects of COVID-19 Vaccination and Intramuscular Vaccine Administration

Vaccines are a public health success story, as they have prevented or lessened the effects of many infectious diseases. To address concerns around potential vaccine injuries, the Health Resources and Services Administration (HRSA) administers the Vaccine Injury Compensation Program (VICP) and the Countermeasures Injury Compensation Program (CICP), which provide compensation to those who assert that they were injured by routine vaccines or medical countermeasures, respectively. The National Academies of Sciences, Engineering, and Medicine have contributed to the scientific basis for VICP compensation decisions for decades.

HRSA asked the National Academies to convene an expert committee to review the epidemiological, clinical, and biological evidence about the relationship between COVID-19 vaccines and specific adverse events, as well as intramuscular administration of vaccines and shoulder injuries. This report outlines the committee findings and conclusions.

Peptides on interstellar ice: Study finds presence of water molecules not a major obstacle for formation

by Marco Körner, Friedrich Schiller University of Jena

A research team led by Dr. Serge Krasnokutski from the Astrophysics Laboratory at the Max Planck Institute for Astronomy at the University of Jena had already demonstrated that simple peptides can form on cosmic dust particles. However, it was previously assumed that this would not be possible if molecular ice, which covers the dust particle, contains water—which is usually the case.

Now the team, in collaboration with the University of Poitiers, France, has discovered that the presence of water molecules is not a major obstacle for the formation of peptides on such dust particles. The researchers report on their finding in the journal Science Advances .

Chemistry in the icy vacuum

"We have replicated conditions similar to those in outer space in a vacuum chamber , also adding substances that occur in so-called molecular clouds," explains Krasnokutski. These substances include ammonia, atomic carbon, and carbon monoxide. "Thus, all the chemical elements needed for simple peptides are present," adds the physicist.

These raw materials , Krasnokutski describes, initially form chemical precursors to amino acids known as aminoketenes. These then combine to form chains, resulting in polypeptides. "It was previously suspected that the individual aminoketenes would bond to form peptides," the scientist explains

"However, for this step, the absence of water might be crucial as it could hinder the reaction. At the same time, most interstellar dust particles are covered with water-containing molecular ice," says Krasnokutski. Hence, the assumption until now has been that if peptides form in space, they do so only to a limited extent.

Precise analysis in France

"The highly precise mass spectrometric analyses now possible at the University of Poitiers, however, showed that the presence of water in the molecular ice slows down the formation of peptides by fifty percent, but they still form," he explains. "When you consider the time scales on which astronomical processes occur, this slowdown is practically negligible."

The question of whether the first biomolecules on our planet are of terrestrial or extraterrestrial origin —or both—will likely remain unresolved for the foreseeable future. However, outer space as a source of our life cannot be ruled out, as this discovery indicates.

6 in 10 U.S. Catholics are in favor of abortion rights, Pew Research report finds

Jason DeRose

Pope Francis remains popular among U.S. Catholics, with 75% having favorable views of him, according to a Pew Research report. But many self-identified Catholics disagree with various teachings of their church. Andrew Medichini/AP hide caption

Pope Francis remains popular among U.S. Catholics, with 75% having favorable views of him, according to a Pew Research report. But many self-identified Catholics disagree with various teachings of their church.

Catholics in the U.S., one of the country's largest single Christian groups, hold far more diverse views on abortion rights than the official teaching of their church.

While the Catholic Church itself holds that abortion is wrong and should not be legal, 6 in 10 U.S. adult Catholics say abortion should be legal in all or most cases, according to a newly released profile of Catholicism by Pew Research .

Catholic opinion about abortion rights, according to the report, tends to align with political leanings: Fewer Catholic Republicans favor legal abortion than Catholic Democrats. And Pew says Hispanic Catholics, who make up one-third of the U.S. church, are slightly more in favor of legal abortion than white Catholics.

Despite church prohibitions, Catholics still choose IVF to have children

Pew found that 20% of the U.S. population identifies as Catholic, but only about 3 in 10 say they attend mass regularly. Opinions about abortion rights appear to be related to how often someone worships — just 34% of Catholics who attend mass weekly say abortion should be legal in all or most cases, whereas that number jumps to 68% among those who attend mass monthly or less.

Most U.S. Catholics are white (57%), but that number has dropped by 8 percentage points since 2007, according the new report. About 33% identify as Hispanic, 4% Asian, 2% Black, and 3% describe themselves as another race.

Pew Research also found that as of February, Pope Francis remains highly popular, with 75% of U.S. Catholics rating him favorably. However, there is a partisan divide, with Catholic Democrats more strongly supporting him.

About 4 in 10 U.S. Catholics view Francis as a major agent of change, with 3 in 10 saying he is a minor agent of change.

Catholic Church works to explain what same-sex blessings are and are not

Pew reports that many U.S. Catholics would welcome more change. Some 83% say they want the church to allow the use of contraception, 69% say priests should be allowed to get married, 64% say women should be allowed to become priests, and 54% say the Catholic Church should recognize same-sex marriage.

In December 2023, the Vatican issued guidance to priests that they may bless people in same-sex relationships. But the church insists those blessings not be construed in any way to be a form of marriage or even take place as part of a worship service.
