The Capability Maturity Model Integration (CMMI) is used by organizations to streamline process improvement and inducing a productive, efficient culture that decreases risks in software, product and service development.
CMMI addresses three areas of interest:
Product and service development - CMMI for Development (CMMI-DEV), Service establishment, management - CMMI for Services (CMMI-SVC), and Product and service acquisition - CMMI for Acquisition (CMMI-ACQ).
CMMI’s five maturity levels are:
Initial: Processes are viewed as unpredictable and reactive. At this stage, “work gets completed but it’s often delayed and over budget.” This is the worst stage a business can find itself in - an unpredictable environment that increases risk and inefficiency.
Managed: There’s a level of project management achieved. Projects are “planned, performed, measured and controlled” at this level, but there are still a lot of issues to address.
Defined: At this stage, organizations are more proactive than reactive. There’s a set of “organization-wide standards” to “provide guidance across projects, programs and portfolios.” Businesses understand their shortcomings, how to address them and what the goal is for improvement.
Quantitatively managed: This stage is more measured and controlled. The organization is working off quantitative data to determine predictable processes that align with stakeholder needs. The business is ahead of risks, with more data-driven insight into process deficiencies.
Optimizing: Here, an organization’s processes are stable and flexible. At this final stage, an organization will be in constant state of improving and responding to changes or other opportunities. The organization is stable, which allows for more “agility and innovation,” in a predictable environment.
