What is the difference between CMM & CMMI? If any.
The Capability Maturity Model (CMM) is a way to develop and refine an organization's software development process. A maturity model is a structured collection of elements that describe characteristics of effective processes. A maturity model provides:
a place to start the benefit of a community’s prior experiences a common language and a shared vision a framework for prioritizing actions a way to define what improvement means for your organization A maturity model can be used as a benchmark for assessing different organizations for equivalent comparison.
The SEI has subsequently released a revised version known as the Capability Maturity Model Integration (CMMI).
Capability Maturity Model® Integration (CMMI) is a process improvement approach that provides organizations with the essential elements of effective processes. It can be used to guide process improvement across a project, a division, or an entire organization. CMMI helps integrate traditionally separate organizational functions, set process improvement goals and priorities, provide guidance for quality processes, and provide a point of reference for appraising current processes.
