I am looking for some logical explanation of how software development fits into a Plan, Build, Run model of an organization. I am struggling to find anything which explains how software development projects fit into this structure. In fact the body of writing appears to be over all very small on PBR. What I do see is something called COBIT from isaca which has 3 stages internally called plan build run. Is this the source of that terminology? I'm looking for some clear where things go, why things go there, and what value that has. I know this may seem a little off topic, but it seemed best under the lifecycle
