Recognizing insufficiencies with all Waterfall based models including their own Vee-Model, Forsberg and Mooz continued to refine their thesis. 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

A paper named “The Relationship of System Engineering to the Project Cycle” written by Dr. Kevin Forsberg and Harold Mooz, Co-Principals for […]
A Funny Thing Happened on the Way to the V-Model
In the late 1980s two countries, Germany and the United States, simultaneously but independently developed a V-Model. While the two models are similar in concept, they differ enough to be considered alternative approaches. The German V-Modell was developed in part by IABG in Ottobrunn, near Munich in cooperation with the Federal Office for Defence Technology […]
