I recently worked on a project for an external client. My colleague and I created a design for a mobile app to help first responders in dangerous situations. We conducted a usability test with 5 participants comparing two competitive designs. 

Recruiting for the test was challenging, we needed to find participants in the medical field that had experience with stressful life and death situations. During the testing we attempted to simulate the experience of having multiple patients with different levels of medical needs. We needed to ensure the user could go back and forth between patients, save the data and run analysis. 

For this project I created the initial test plan with my colleague. I conducted all the user testing, and he did the data analysis and wrote the final report. Below is a few exerts from the final report.
