Assumptions are just that—assumptions. My team and I made assumptions that were ultimately invalidated after interviewing users, but sitting down with users helped us to learn what their needs actually were.
Understanding your teammates strengths and weaknesses is important. Sitting down with each member to talk about which aspects of design, research, and collaboration they excelled in helped me to delegate appropriate tasks.
Time management is key! My teammates and I (along with the interviewees) are college students with busy schedules. I learned the hard way that planning in advance is important, and how important it was for my team to capitalize on the little shared time we had.
I enjoy creating and working with design systems! Being able to create a consistent foundation for my product felt like creating puzzle pieces and then placing those pieces together. It was a very satisfying experience that drove me to be creatively strategic.
