I shared the story of our patterns & practices Engineering Practices Frame on Shaping Software.  In a nutshell, the Engineering Practices Frame is a set of categories to organize software development knowledge.  The idea behind the frame is to help collect and share principles, patterns, and practices for life cycle activities and artifacts.  It's meant to play well with SWEBOK, various Microsoft efforts around life cycle practices, and our customers and field in the trenches.  The Engineering Practices Frame is also the foundation for our ALM Frame.
