The library was created by 5 designers on my team. Each designer was assigned a few component per sprint to design and spec out. We would work together to make sure it was ADA complient, consistent with the rest of the library and solved business needs. Once it was approved by the design team, I would present it to the development team to get their feedback and talk through the functionality. Once it was developed, QA sessions would be completed to insure the library was coming to life corrently and functioned the way we imagined.
The library was designed to work for both a B2B and B2C products. The business centered library was created first because most of the applications at RealPage are B2B but we made sure to create how it would translate to a consumer look and feel. The library is able to be altered to have a softer design look and it is also color customizable.
