SAS Analytics Platform went through about 94 different iterations and variations. In retrospect, I think it struggled with trying to do too much. It allows users to do three different analytical operations in the same place: forecasting, text analytics, and predictive modeling. I was the lead designer but there were three of us working simultaneously, along with three engineering teams, two of which were remote, and three different product managers.
I learned a lot on this project. I learned about communicating design ideas with unfamiliar audiences. I learned about managing and accommodating competing opinions. I learned about designing for scale.
The screens below are not the same as the prototype version but help demonstrate some of the variation.
