They presented a Dual Vee-Model in a 2006 paper titled “The Dual Vee – Illuminating the Management of Complexity.” In the abstract they said: The Waterfall, Spiral, and Vee models are reminder models that guide us […]
US Vee Model
The US Vee-Model was first discussed at a joint conference sponsored by the National Council on Systems Engineering (NCOSE) and American Society for Engineering Management (ASEM) in Chattanooga, TN on October 21–23, 1991. A paper named “The Relationship of System Engineering to the Project Cycle” written by Dr. Kevin Forsberg and Harold Mooz, Co-Principals for […]
Best of the Best Practices
In Chapter 2 of The Ultimate Guide to the SDLC, 12 historical system development models, both agile and waterfall based, are compared as well as one hybrid and one philosophy. The best practices from each model are extracted and extrapolated into a best of best practices model. None of the Waterfall or Agile models provide […]
