Maturity Model
Nov 06, 2017

The Capability Maturity Model (Capability maturity models, the English abbreviation for CMM) is a development model. Researchers at the University of Carnegie Mellon collected data from the U.S. Department of Defense contractors and studied it and proposed a CMM. The U.S. Department of Defense funded the study. Carnegie Mellon founded the Software Engineering Institute (SEI) based on the model. The goal of CMM is to improve the existing software development process and other processes.

It is a description of each development phase in the software organization's practice of defining, implementing, measuring, controlling, and improving its software processes. The core of CMM is to regard software development as a process, and to monitor and study the process of software development and maintenance according to this principle.

CMM is a method for evaluating software contracting ability to improve software quality, focusing on the management of software development process and the improvement and evaluation of engineering capability. It is divided into five levels: first level, Level two is repeatable, three is defined level, four level is management level, and five level is optimization level.

The assumption is: as long as the focus on continuous efforts to establish an effective software engineering process infrastructure, continuous management practices and process improvements, you can overcome the difficulties in software production.
