Abstract: A system and method for selection of development processes that require corrective action is presented. A process improvement lessons learned procedure classifies and assigns priority rankings to improvable development processes. A process improvement lessons learned procedure includes several stages of list expansions and reductions that consider the probability of poor use of resources, the probability of a process being ineffective, and the probability of a process causing schedule impacts. The probabilities are multiplied together to not only provide a list of continuous improvement possibilities a team addresses, but a continuous improvement priority ranking provides a team with the order in which resources should be applied to each improvable development process.
