A lot of people seem to follow the errors of Design Patterns and focus on structure to the exclusion of process. A pattern description should tell the reader how to create the pattern in a system where it doesn't exist, and many pattern descriptions do not.One of the things that helps me think about process is to imagine a system without the pattern. What would I do to use the pattern in the system? What alternatives are there to the pattern?
