I spent an hour reading this paper. This whitepaper is a very well written and organized ?tie-together? for object based analysis, development, and design. It doesn?t go into deep detail about the various key techniques (UML, use-cases, sequence diagrams, or code) because there are already books filled with information about them, but rather details how to tie them together into a cohesive toolset. Following the examples given will prevent diagrams from becoming useless overhead and will allow them to be used as valuable development tools.
