The design sprint was 4 days long, and led by me and an in-house designer at IFS.
Day 1 was dedicated to understanding the problem. Group discussions with the many subject matter experts helped everyone to get on the same page.
Day 2 was for brainstorming and sketching as a group. The majority of participants were coming from a financial background. They were empowered to think like designers and even do their own UI sketches.
On day 3, the group decided on a direction, and the UX team got to prototyping.
On day 4, we got feedback from the group on our prototypes, and did remote usability testing sessions with actual users.
After the sprint, I worked to flesh out the wireframes that we had generated. This was done in consultation with the subject matter experts in the company. With such a complex product in a highly regulated industry, it was important to get their input as I designed.
