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

A case study of a video-creation platform

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.
