How to blend CMMI and Scrum? [closed]

Answer 1

This seems an interesting paper by the SEI folks at Carnegie Mellon (not just about Scrum though):

CMMI and Agile are compatible. At the project level, CMMI focuses at a high level of abstraction on what projects do, not on what development methodology is used, while Agile methods focus on how projects develop products. Therefore, CMMI and Agile methods can co-exist

Answer 2

Here is an experience report on the results of introducing Scrum into a CMMI Level 5 environment to replace waterfall projects for large defense and healthcare contracts (pdf).

Abstract:

Projects combining agile methods with CMMI1 are more successful in producing higher quality software that more effectively meets customer needs at a faster pace. Systematic Software Engineering works at CMMI level 5 and uses Lean Software Development as a driver for optimizing software processes. Early pilot projects at Systematic showed productivity on Scrum teams almost twice that of traditional teams. Other projects demonstrated a story based test driven approach to software development reduced defects found during final test by 40%. We assert that Scrum and CMMI together bring a more powerful combination of adaptability and predictability than either one alone and suggest how other companies can combine them.

HTH,
