How to Craft an Outstanding Case Study for Your UX Portfolio

Writing case studies for your UX portfolio can feel opaque and overwhelming. There are so many examples out there, and often the ones that make the rounds are the stunning portfolios of top visual designers. It can be inspiring to see the most beautiful work, but don’t let that distract you from the straightforward format of a good UX case study. 

At the core, a UX case study relies on excellent storytelling with a clear, understandable structure . This article breaks down the anatomy of a UX case study to help you tell a simple and effective story that shows off your skills. We’ll start with some general guidelines and structure, then break it down one piece at a time:

1. Before we get started

Before we dive into all the art and science of the case study, here’s a quick refresher on what a job-winning UX portfolio looks like. In this video, pro designer Dee analyses various design portfolios to pick out what works—and what doesn’t:

Simply put, a case study is the story of a design project you’ve worked on. The goal, of course, is to showcase the skills you used on the project and help potential employers envision how you’d use those skills if you worked for them.

A case study is typically written like a highly visual article, with text walking readers through a curated set of images. Curated is an important word here, because it should be short and sweet. It’s a chance to share what you want potential employers to know about your work on this project.

With that in mind, case studies are really a UX designer’s secret weapon in two ways. First, they get you in the door by showing more about your work than a resume and a top UX cover letter ever could. Another benefit is that they’re really handy in job interviews. If someone asks about a past project, you can walk them through the case study you’ve already created (this is sometimes a requirement anyway).

I mentioned that UX case studies are about storytelling. I’d actually say they’re about stories-telling, since they need to tell two intertwined stories .

The first is the story of your project. This answers questions like what problem you solved, who your users were, what solutions you explored, and what impact they had.

The second story is about you as a designer and your process. This is more about which methods you chose to use and why, how you worked within constraints, and how you worked as a member of a team (or without one).

So what are the steps for an effective case study? Well, like most things in design (and life), it depends. Every case study will be different, depending on what stories you’re telling. The six-part outline below, though, should guide you through an effective format for any UX project story. Here’s the outline (we’ll dive into each component in just a minute):

• Defining the Problem
• Understanding your Users
• Final solution

It’s worth it to add a few general notes before we dive into each of the list items above. For each section, include 1-2 short paragraphs and an image of a deliverable that visually tells the story your paragraphs explain. A reader should be able to either just read or just look at the images and roughly get what this moment in the story is communicating.

When choosing images to include, focus on quality over quantity.  Choose your best deliverables for each stage and briefly relate them back to the larger narrative. It can be tempting to overload the page with everything you created along the way, but these extra details should stay in your back pocket for interviews.

Lastly, make sure your case study is scannable . In the best of circumstances, people don’t read word for word on the web. Make sure your text is reasonably concise, use headers and strong visual hierarchy, and use bullet points and lists when possible. If you need a refresher on how to achieve this, check out our guide to the principles of visual hierarchy .

Ok, let’s take a look at each step in a bit more detail.

2. Anatomy of a UX case study

Like any story, the introduction sets the stage and gives much of the necessary context readers will need to understand your project. This is one section where people actually might take some extra time to read carefully as they try to discern what this case study is about. Make sure they have all the details they need.

Some key questions to answer are:

• What is your company and/or product?
• What user problem did you try to solve?
• What was your role?
• What tools and methods did you use?
• What are the major insights, impacts, or metrics related to the project

After introducing the project, dive more deeply into the problem you tackled. You touched upon this in the introduction, but this section is an opportunity to make a strong case for why this project exists. Did a competitor analysis or market research demand a new product? Was there past user research in your company that suggests a needed redesign of the product?

Remember that you’ll want to create a through line in the narrative, so try to lay out the problem in a way that frames your design work as a solution.

Deliverables that work really well for this section would be:

• Analytics or usage data
• Market research of internal business metrics
• Survey results or interview highlights

After explaining the problem, show how it impacts your users and their interaction with your product. If you did original user research or you’re seeking user research-oriented jobs, sharing interview scripts, affinity maps , and spreadsheets can be useful in showing your process.

However, this section shouldn’t be only about your process. A key goal of this section is articulating who your users are and what their needs are. These findings should set up your design work that follows, so try to set up that connection.

A few types of the deliverables you might share here are:

• User personas
• Mental models
• Journey maps or customer experience maps

Keep in mind you want to communicate users’ key motivations and challenges, as well as any more specific user groups you identified.

This section can really scale up or down depending on what you have to show. Research shows that hiring managers  don’t just want the final product , so it’s clear that showing some of your process is helpful. Especially for students or designers without a fully built product to show, this can be a moment for you to shine.

Don’t worry about the low fidelity of these documents, but the rougher they are, the more you’ll need to guide readers through them. Everything you show here should teach the reader something new about your process and/or your users.

Artifacts you might include are:

• Pen and paper or low fidelity digital wireframes

If you did early testing or faced constraints that determined your future design work, be sure to include them here, too.

This section should include the most final work you did on the project (e.g. wireframe flows or color mockups) and any final product it led to (if you have it). Be clear, though, about which work is yours and which isn’t.

Explain any key decisions or constraints that changed the design from the earlier stages. If you incorporated findings from usability testing, that’s great. If not, try to call out some best practices to help you explain your decisions. Referring to Material Design, WCAG, or Human Interface Guidelines can show the why behind your design.

If you’re able to show the impact of your work, this can take a good case study and make it outstanding. If your project has already been built and made available to users, have a look at any analytics, satisfaction data, or other metrics. See what you could highlight  in your case study to show how your design improved the user experience or achieved business goals. Ideally, you can refer back to your original problem statement and business goals from the introduction.

If you don’t have any way of showing the impact of your project, lay out how you would measure the impact. Showing you know how to measure success demonstrates you could do this on future projects.

Lastly, conclude your case study by sharing either your next design steps and/or some key insights you learned from the project. This isn’t just fluff! No project is perfect or final. Showing next steps is a great way to demonstrate your thinking iterative approach (without having to do the work!).

Also, many companies do (or should do) retrospectives after each project to identify challenges and improve future processes. Use this process and the insights you gain from it to inform your case study. Letting employers know you’re capable of reflection shows humility, self-awareness, and the value you can bring to a team.

3. Final thoughts

Since each case study is a unique story you’re telling about your project, it’s a little art and a little science. But starting with the structure laid out in this article will show who you are as a designer and how you solved a problem. And those are two stories companies want to hear!

The benefits of ux case studies, examples of ux case studies, tips for creating a ux case study.

UX portfolios are essential to showcasing UX designer skills and abilities. Every UX designer knows better designs bring better results. Sometimes, it’s easy to let the design speak for itself — after all, it is meant to engage the audience.

But, in doing that, you, as the designer, leave many things unsaid. For example, the initial problem, the need for the design in the first place, and your process for arriving at the design you created.

This is why you need to include UX case studies in your portfolio.

UX case studies tell a curated story or journey of your design. It explains the “who, what, when, where, and how” of your design. The text should be short and sweet but also walk the reader through the thinking behind the design and the outcome of it.

11 Inspiring UX Case Studies That Every Designer Should Study

A UX case study is a sort of detailed overview of a designer's work. They are often part of a UX designer's portfolio and showcase the designer's skill in managing tasks and problems. From a recruiter's perspective, such a UX portfolio shows the skill, insights, knowledge, and talent of the designer.

Therefore, UX case studies play an important role in the recruitment and demand for designers.

What Makes a Powerful Case Study

Building a UX case study includes showing the design process through compelling stories. They will use plain language to demonstrate how they handled key design issues, offering a comprehensive view of their process. Well done case studies often include:

• A  problem statement and solutions with real applications.
• Relevant numbers, data, or testimonials to demonstrate the work and efforts.
• A story that directly connects the problem to the solution.

Any competent UX professional will know that creating a stunning UX case study is about the little details.

11 Best UX Case Studies for Designers

The best way to understand what a good case study looks like is to go over other examples. Each of these UX case study examples shows a designer's insights, basic skills, and other designers' lessons learned through their experience.

1. Promo.com web editor

For this video-creation platform , UX designer Sascha was brought on to revamp v2.0, adding new features that could work alongside the existing UX design. The point was to work on interface details that would help create a user friendly platform, and that users could find simple enough to use.

User personas mapped by the UX designer revealed the most common confusion to be the process of inserting particular features into the video, such as subtitles. The designer's goal, therefore, was to create a platform with improved editor controls.

The designer then used a common text-editor layout to include top and side navigation bars that made it easy to access and implement text editing.

Key Learnings from Promo.com

This case study focuses on addressing a particular problem that customers were currently facing. Its main theme is to show a problem, and how the product designer addressed this problem. Its strength points include:

• clearly highlighting the problem (i.e. inaccessible and limited video-text editor options)
• conduction research to understand the nature of the problem and the kind of solutions customers want
• implementing research insights into the redesign to create a platform that actively served customer needs

2. Productivity tracker app

The main concept behind this UX case study is to address a pre-existing problem through the design of the app. Immediately from the start, the study highlights a common pain point among users: that of a lack of productivity due to device usage.

This UX case study example addressed some of the main problems within existing productivity apps included:a poor UI and UX that made navigation difficult

• a poorly-built information architecture
• limited functions on the mobile application

Key Learnings from the Productivity app case study

The case study highlights the simple design process that was then used to build the app. Wireframes were created, a moldboard developed, and finally, individual pages of the app were designed in line with the initial goals.

3. Postmates Unlimited

This case study clearly identifies the improvements made to the Postmates app in a simple overview before jumping into greater detail. The redesign goal, which it achieved, was to improve the experience and other interface details of the app.

The problems identified included:

• usability that led to high support ticket volume.
• technical app infrastructure issues that prevented scalability.
• lack of efficient product management, such as batching orders.

A UX research course can help understand the kind of research needed for a case study. The app redesign involved bringing couriers in and running usability testing on improvements. The final model, therefore, had input from real users on what worked and what caused issues.

Key Learnings from Postmates

The Postmates redesign works as a great UX case study for the simple way it approaches problem-solving. Following an overview of the work, it addresses the problems faced by users of the app. It then establishes research processes and highlights how changes were made to reduce these issues.

4. TV Guide

Addressing the fragmentation of content across channels, this case study sought to redesign how people consume media. The key problems identified included:

• the overabundance of content across various TV and streaming platforms
• the difficulty in discovering and managing content across all platforms

To deliver on the key goals of content personalization, smart recommendations, and offering cross-platform content search, the design process included conducting interviews, surveys, and checking customer reviews.

The design of TV Guide enables users to get custom recommendations sourced from friends' and family's watchlists.

Key Learnings from TV Guide

Like previous UX design case studies, this one tackled the issue head-on. Describing the research process, it goes into detail regarding the approach used by the UX designers to create the app. It takes readers on a journey, from identifying pain points, to testing solutions, and implementing the final version.

5. The FlexBox Inspector

Designer Victoria discusses how she developed the investigator tool for the Mozilla Firefox browser. Surveys into understanding the problems with the existing CSS Flexbox tool revealed a need for a user-friendly design. Interviews with a senior designer and other designers helped developers understand the features design-focused tools ought to have. A feature analysis revealed what most users look for in such tools.

The final result of the development process was a design that incorporated several new features, including:

• a new layout
• color-coded design
• multiple entry points to make workflow management efficient

Key Learnings from the Flexbox

This UX design case study starts with a clear goal, then addresses multiple user needs. It clearly defines the design process behind each feature developed by the time, and the reasoning for including that feature. To give a complete picture, it also discusses why certain features or processes were excluded.

6. The Current State of Checkouts

This Baymard UX design case study looks into the checkout process in over 70 e-commerce websites. Through competitive analysis, it isolates problem points in the UX design, which, if addressed, could improve the customer's checkout process.

The study found at least 31 common issues that were easily preventable. The study was designed and conducted on a large scale, over 12 years, to incorporate changing design patterns into the review.

Recommendations based on findings include:

• prominent guest checkout option
• simple password requirements
• specific delivery period
• price comparison tool for shipping vs store pickup

Key Learnings from Checkout Case Study

Each identified issue is backed up by data and research to highlight its importance. Further research backs up each recommendation made within the case study, with usability testing to support the idea. As far as UX case studies go, this one provides practical insight into an existing, widely used e-commerce feature, and offers practical solutions.

7. New York Times App

Using a creative illustration website, the designers proposed a landing page feature "Timely" that could counter the problems faced by the NYT app . Its major issues included too much irrelevant content, low usage, and undesirable coverage of content.

The goal behind Timely was to improve user incentives, build long-term loyalty, and encourage reading. Design mapping for the app covered:

• identifying the problem
• understanding audience needs
• creating wireframes
• designing and prototyping

The end result was an app that could help readers get notifications regarding news of interest at convenient moments (at breakfast, before bed). This encouraged interaction and improved readability with short-form articles.

Key Learnings from NYT App

The UX case study proposes a problem solution that works with an existing information architecture, instead adding custom graphics to the mobile app. It leads from a simple problem statement to discuss the project that could address these issues without changing was customers already loved.

UX case studies focused on redesign include the FitBit redesign, which started off by understanding personas and what users expect from a fitness tracker. Developing use cases and personas, Guerilla usability testing was employed to assess pain points.

These pain points were then ranked based on their importance to users and to app performance. They were addressed through:

• Highlighting essential parts and features of the app
• Changing easily missed icons to more recognizable icons
• relabelling tracking options to guide users better to its usage

Key Learnings from Fitbit

While the case study maps user experiences and offers solutions, it does not begin with an intensive research-based approach. The prototype is successful in testing, but problem factors are not identified with research-based statistics, meaning key factors could have been ignored.

9. Rating System UX

The designer behind the rating system UX redesign sought to solve issues with the 5-star rating system. Highlighted issues included:

• the lack of subjective accuracy of a 5-point rating system
• the issue of calculating the average of a zero-star rating
• average ratings are misleading

Better alternatives include:

• 5-star emoticon rating that relates the user experience
• Like/dislike buttons that make approval/disapproval simple

The final design incorporated both these styles to make full use of the rating system.

Key Learnings from Rating System UX

The UX case study stemmed from insight into the limitations of the existing rating system. The new design addressed old issues and incorporated better efficiencies.

The Intuit redesign was focused on making content readable, more engaging, and accessible. Looking into product personalization, the content was found to be lacking aesthetic value, as well as being hard to find. The goal was to create content that was easy to find, clear, and consistent.

The implemented solutions included:

• increased readability with increased body text and header spacing
• table of contents on the sidebar for easier navigation
• visible and prominent search bar
• illustrations and designs for pretty visuals

Key Learnings from Intuit

The Intuit case study approaches the problem from a practical point of view. It begins with isolating problems with the interface, in particular with the content. This is an example of a case study that breaks down problems into broader categories, and solves each problem with a practical solution.

This UX case study about a social platform tackles a commonly-faced problem from existing platforms. It addresses the issue of recognizing non-monetary user engagement, to help creators identify their user base.

The case study addresses the problem statement and establishes the design process (building wireframes and prototypes) as well as conducting user testing. The final result is to develop "Discover" pages, engaging layouts, and animated interactions to increase usability.

Key Learnings from Jambb

The study goes into detail regarding problem identification, then moves on to propose solutions that take into account the perspective of all stakeholders involved. It then explains why each design decision was made, and proves its efficacy through testing and prototyping.

Key Takeaways

Developing good UX case studies examples is as much about the details you include as the ones you leave out. Going over UX courses can give you a better understanding of what your case study should look like. A good case study should provide an overview of the problem, include numbers and statistics, and offer practical solutions that directly address the problem. The above-discussed UX case studies provide a good example of the dos and don'ts of a well-structured UX design case study that should be part of every UX portfolio .

The Ultimate Guide to Writing a UX Case Study That Converts

Writing a UX case study can be hard. There are so many ways to do it, and even more hiring managers and designers have an opinion on how to do it. How do you know which is the way to go?

• Updated on May 8, 2024

That’s where this post comes in. I’ve been in UX for almost ten years now, and during that time, I’ve been on the job hunt myself multiple times while also helping companies hire the right designer.

It means I know a thing or two about the importance of UX case studies as a part of your UX portfolio and how to write one that converts into a job interview. 

Table of Contents

Writing a first quick draft.

To make writing a UX case study less overwhelming, I suggest starting with a one-paragraph summary first. It helps you pinpoint what’s actually important within your case study.

Here’s an example.

“As an entry-level UX designer at the Dutch Bank, I designed a new version of their mortgage calculation tool. Since then, the bank has seen an 8% increase in mortgage requests.”

This example consists of three parts.

• What you did

We’ll discuss how to turn this paragraph into the full UX case study text later, but first, write down the one-paragraph summaries for all case studies you want to create.

If you’re an entry-level designer, one case study is enough. There’s no real set number of case studies you need. I’d rather read one strong case study than three ‘okay’ case studies.

Did you write your one-paragraph summaries? Great! Up next, it is time to turn those summaries into complete UX case studies . You can read about it on our website or watch how we approach this step in one of our 5-Minute Figjam Fixes below.

Sharing your case study

Now that you’ve written your case study, it is time to share it with your network. There’s one super important thing to keep in mind.

Writing and sharing your UX case studies is like a UX project where your case study is the product, and the people who can hire you are your users.

That means you have to design something (your case studies) in a way that helps your users (recruiters and hiring managers). You can do this by talking to your users.

You can do this in many different ways. Here’s a list of examples.

• Share your first full case study draft with five (senior) designers and ask them for UX-related feedback.
• Share your case study with five business owners and ask them if they understand what the case study is about.
• Share your case study with recruiters and ask if they know companies that would benefit from similar work.

Doing the above will get you real-life feedback from different user types. Do this early on and often.

In a perfect world, you’d start with this when you only have the text for your case study. That’s because you can change text much quicker before it makes its way to Webflow, Framer, or another portfolio builder.

This way of improving your case studies based on feedback is never done. Even after working in UX for almost ten years, I still finetune my case studies often. However, you should see an increase in engagement (and possibly leads) after two or three case study iterations.

Presenting your UX case study

If everything is going to plan, you could have received an invite for a job interview by now. Congratulations, first of all! But how do you ace your case study presentation?

Here’s a list of tips and tricks to help you.

• Arrive on time and test your audio, video, and internet before.
• Position yourself in the middle of the frame.
• Focus on the ‘jobs to be done’ of your case study.
• Don’t tell everything right away. Start with a summary and allow your audience to ask questions first.

The final item on the list is especially important. If you tell too much right away, your audience might doze off. Also, if you tell too much right away, you take away your ‘easy questions.’

There’s more you can do to help you present your UX case studies , but the list above should cover most of it.

That’s everything you need to know about creating super-strong UX case studies. If you follow along from start to finish, you should be alright.
