CMM (Capability Maturity Model) vs CMMI (Capability Maturity Model Integration)
Aspects |
Capability Maturity Model (CMM) |
Capability Maturity Model Integration (CMMI) |
---|---|---|
Scope |
Primarily focused on software engineering processes. |
Expands to various disciplines like systems engineering, hardware development, etc. |
Maturity Levels |
Had a five-level maturity model (Level 1 to Level 5). |
Initially had a staged representation; it introduced continuous representation later. |
Flexibility |
More rigid structure with predefined practices. |
Offers flexibility to tailor process areas to organizational needs. |
Adoption and Popularity |
Gained popularity in the software development industry. |
Gained wider adoption across industries due to broader applicability. |
Levels of CMMI
CMMI, like CMM, is organized into five stages of process maturity. However, they differ from the levels in CMM.
There are 5 performance levels of the CMMI Model.
Level 1: Initial: Processes are often ad hoc and unpredictable. There is little or no formal process in place.
Level 2: Managed: Basic project management processes are established. Projects are planned, monitored, and controlled.
Level 3: Defined: Organizational processes are well-defined and documented. Standardized processes are used across the organization.
Level 4: Quantitatively Managed: Processes are measured and controlled using statistical and quantitative techniques. Process performance is quantitatively understood and managed.
Level 5: Optimizing: Continuous process improvement is a key focus. Processes are continuously improved based on quantitative feedback.
Capability Maturity Model (CMM) – Software Engineering
The Capability Maturity Model (CMM) is a tool used to improve and refine software development processes. It provides a structured way for organizations to assess their current practices and identify areas for improvement. CMM consists of five maturity levels: initial, repeatable, defined, managed, and optimizing. By following the CMM, organizations can systematically improve their software development processes, leading to higher-quality products and more efficient project management.
