What Model do I use?

• Historically: Depends on the discipline that you want to model. –Software Engineering –Systems Engineering –Software Acquisition –Systems Security –etc.

What is a CMM?
• Capability Maturity Model: A reference model of mature practices in a specified discipline, used to assess a group’s capability to perform that discipline• CMMs differ by –Discipline (software, systems, acquisition, etc.) –Structure (staged versus continuous) –How Maturity is Defined (process improvement path) –How Capability is Defined (institutionalization) • “Capability Maturity Model®” and CMM® are used by the Software Engineering Institute (SEI) to denote a particular class of maturity models

•Different structures, formats, terms, ways of measuring maturity •Causes confusion, especially when using more than one model •Hard to integrate them in a combined improvement program •Hard touse multiple models in supplier selection

Bridging the Divide
• Systems and software disciplines have traditionally not been well integrated • The importance of software in systems has increased dramatically – Example: % of requirements allocated to software: *
» B-2 -- 65% » F-22 -- 80%
Systems Software

• The DOD has emphasizedthe need to make the systems/software interface more seamless

CMMI to the Rescue!
• Integrates systems and software disciplines into one process improvement framework.

• Provides a framework for introducing new disciplines as needs arise.
