Effective Hybrid Agile Approach?
Saying the CMMI can help a Hybrid Agile approach succeed might surprise
some people. What I mean is that by using the CMMI and proven Agile prac-

projects succeed by providing project personnel with the training and
process aids to help effectively execute their agreed-to Agile approach.
Following are five examples that demonstrate how specific CMMI practices
could have helped us effectively implement our hybrid Agile approach, and
potentially deploy the modernized DART system in less time.
