Yahoo! designed and built a repository for interaction design patterns, created a process for submitting and reviewing the content, and seeded the resulting library with a set of sample patterns. They organized the content to make it findable, structured the content so it was predictable, and tested and iterated the design of the user interface of the tool to make it usable.

Throughout this process, they introduced incentives for participation for both the contributors and management to encourage submissions and support.
