Capability Maturity Model (CMM)

What is Capability Maturity Model (CMM)?

The Capability Maturity Model (CMM) is a model for a company’s software development process to be developed and refined. It isn’t a software process model. It is a framework for analyzing any organization’s approach and practices when developing software products.

It also includes advice for further improving the maturity of the software development process. CMM is built on the most effective feedback and growth strategies used by the world’s most successful firms. This model offers a software process improvement method that should be followed by progressing through five tiers.

The model represents a five-level evolutionary process that grows more orderly and systematic as it develops. Each maturity level represents a level of process capability. Key Process Areas (KPAs) are used to characterize all levels except level 1.

The entire CMM level is divided into five different levels.

  • Level 1: where requirements for the system are usually uncertain, misunderstood, and uncontrolled. The process is usually chaotic and ad-hoc.
  • Level 2: estimate project cost, schedule, and functionality. Software standards are defined for management purposes.
  • Level 3: makes sure that the product meets the requirements and intended use to define what is required in the project.
  • Level 4: helps with the management of the project’s processes and subprocesses statistically for quality purposes.
  • Level 5: Identify and deploy new tools and process improvements to meet needs and business objectives.
