Software development process basically
consists of phases, planned and executed in series: 1) feasibility study; 2) requirements; 3) design and 4) implementation, prior toproduction and maintenance. At the end
of each phase, there may be an official management decision (go/not go)
depending upon cost, time or other reasons. Within each phase or across-phases,
parallelism or concurrency can be achieved if modularity and/or independence of
functionality exist(s).
We propose a different approach to software development process that allows an
improved parallel planning and execution of development effort beyond
modularity and functionality independence. The goal is to shorten development
time while possibly cutting cost and maintaining the same intended quality of
performance. An example development is sketched.
