  • Coaches need a better tool to track athletes’ performance.
  • Easily input the evaluation data and share it with the team.


Create a mobile app for coaches to be able to input, share and display the evaluation of the athletes.

User Pain Points



The paper data is very easy to disappear, and the coaches are not able to compare the previous evaluations, performance or notes.



It’s crucial and sometimes difficult to keep the team motivated and focused on the same goal.



Coaches need a better tool to evaluate the team and to share the result as a team or individually. 

User Journey Map


Paper Wireframe

In the early phase of design, I used the paper wireframe to quickly brainstorm and write down the ideas. 

Digital Wireframe

The above shows the main user flow, which was to input the evaluation of the athletes and share the result. 

Low-Fidelity Prototype


In the bottom menu bar, there are 5 main features:

  1. Athlete: where athletes’ performances, injury history, and both physical and mental situations were displayed for coaches to better understand everyone on the team.
  2. Match: this app also provides a better way to organize matches and games.
  3. Evaluation: where coaches could add evaluation sessions and input data.
  4. Share: the team could use this app to communicate and share files such as the evaluation results, team schedule, and notes.
  5. Team: the setting function


On this page, coaches can quickly switch between athletes by horizontally scrolling their profile photos.

When an athlete was chosen, first the athlete’s name and basic information will show, and the evaluation items could be input by the sliding bar and additional notes could be added by typing or audio recording which could save more times. 


The recruiter gave me some precious feedback on my design challenge and what I could do to improve my design skills in the future. Although I didn’t get the chance to work in this company, the recruiting experience is more valuable than the result. I really appreciate that they spend time and effort giving feedback via an online meeting just as I did on the design challenge. 

Here I want to share a few points they shared with me:

  •  Although the whole design flow is good, every point I made seems rather alone and not connected.
    • My design should have a core value and every feature in my design is to solve the problem and improve the experience.
  • I focused too much on the sentence they gave me and didn’t really dig into the real problem. 
    • I should empathize with the target users more. For example, understand a coach’s daily struggles while leading the team.
    • “Fall in love with the problem, not the answer”

Also 2 points to improve myself:

  • Solve real challenges
    • No matter how small the problems might be, really try to talk to people and understand their struggles and needs. 
  • Set up key performance indicators (KPIs)
    • How to measure the success of your design

This case study is not the typical one to show my design skills and knowledge, but it’s to record the experience I’ve been through and my ability to accept feedback and keep on going!

I will keep going to improve myself! Fighting! 🙂
