WINS: 1. We built the most comprehensive and consistent component library in our org's history with two people. 2. We received praise from fellow designers with comments such as "cuts mocking up time in half" and "I don't have to look in 12 different files to find the three assets I need." 3. The libraries were not only used by the UX team but also creative services to assist in their mock ups. 4. Through subsequent research, we received a System Usability Score of 85, well above the average of 68. 5. We fixed accessibility in a number of areas, especially on the main button components which, in the previous app iteration, had failed contrast ratio standards.  6. Removing unnecessary images (eg. the previous tile backgrounds were very image heavy) reduced load time. 7. Dark mode was implemented. 8. The app shipped! ​​​​​​​ LOSSES: 1. Although we were able to implement some features that we were excited about, the fact that this wasn't considered a full redesign by the top brass means that we couldn't secure the development resources to implement features like: metadata outside the tile space, default images as fallbacks for no artwork, album art dominant colors in now playing background, and additional onboarding features to explain things like Pandora Stations and Xtra Channels. 2. Although our SUS score was above average it was lower than our previous app iteration. According to the research conducted the addition of features like Pandora Stations without much onboarding confused some users and dragged the score down. 3. The brand guidelines that we needed in order to create our own visual UI guides were created in a silo where app design was not considered. We ended up having to bend a lot of brand standards to make them work in what we were creating. 4. After a corporate re-org I was placed on a different team and no one was given the stewardship of the design system. It was in use for about 5 months at that point. 5. Lack of QA resources was a let down 6. The goal of writing thorough usage guidelines didn't pan out due to lack of resources We set out to create a tool that would not only save our designers time but could act as a conduit, communicating across different teams the building blocks that make up a SiriusXM product. To some extent we accomplished those goals, especially with only two designers on the project. Our designers praised it and, to this day (Feb 2021), a good portion of it is reflected in the current in-market SiriusXM app. That being said, it takes a commitment beyond 2-3 people to make something like this really stick; good design needs to be in the organization's DNA. And good design is the product of good communication, whether it's with users or fellow designers. So did we fully break down the silos that kept us from achieving app design utopia? No. But we definitely poked a few holes to let some sun shine in.
