The Capability Maturity Model (CMM) for Software (SW-CMM) is a framework that helps organizations improve their software development and maintenance processes. It outlines five maturity levels, key process areas, and common features that define the degree of process maturity in an organization. The SW-CMM emphasizes the importance of process maturity in achieving consistent and lasting improvements in software process capability. It provides guidance on how to gain control of software processes and evolve toward a culture of software engineering and management excellence. The SW-CMM is based on the principles of product quality and focuses on the continuous improvement of software processes. It describes the difference between immature and mature software organizations. Immature organizations are reactive, with processes that are often improvised and not rigorously followed. In contrast, mature organizations have well-defined, consistent, and controlled processes that are used across the organization. The five levels of software process maturity are: Initial, Repeatable, Defined, Managed, and Optimizing. Each level represents a stage in the evolution of an organization's software process. At the Initial level, processes are ad hoc and often chaotic. At the Repeatable level, basic project management processes are established. At the Defined level, processes are documented and standardized. At the Managed level, processes are quantitatively understood and controlled. At the Optimizing level, continual process improvement is enabled through quantitative feedback and innovation. The SW-CMM provides a framework for organizing these evolutionary steps into five maturity levels that lay successive foundations for continual process improvement. These levels help organizations prioritize their improvement efforts. The SW-CMM also includes key process areas that indicate where an organization should focus to improve its software process. Each key process area is organized into common features that specify the key practices needed to achieve the goals of the key process area. The SW-CMM is a living document and is currently under development for Version 2. Version 2 will include changes such as incorporating process evolution, providing finer granularity of process rating, and adding goals to capture the institutionalization of processes. The SW-CMM is a useful tool for guiding software process improvement efforts and has been widely adopted by the software community. It represents a broad consensus of the software community and is a useful tool for guiding software process improvement efforts.The Capability Maturity Model (CMM) for Software (SW-CMM) is a framework that helps organizations improve their software development and maintenance processes.
