In a lecture, the lecturer described the following model : E - entry (the preconditions to a task). T - task - doing the task V - verifying the tasks quality D - Delivering the tasks X - Exit. or ETVDXIf anyone is familiar with this 'generic compliance model', how does it fit into software development exactly? I presume it's equivalent to the waterfall model of negotiating requirements > defining/decompose stage > estimating effort > estimating resources > developing schedule. 
How does the ETVDX model fit in with project management?
