5 levels of CMM/cmme

CMM/cmme divides the maturity of software processes into five levels. The following are the basic features of the five levels:

(1) initial level (initial ). Work is out of order, and the original plan is often abandoned during the project process. There is no rule and a sound management system. The development project is not stable. The project's success mainly depends on the experience and ability of the project owner. Once the project owner leaves, his work is completely out of order.

(2) repeatable ). Management is systematic, and basic management systems and procedures have been established. Preliminary Implementation of standardization, development work better according to standards. Changes are implemented in accordance with the law, so as to achieve baseline, stability and tracking. the planning and management of new projects are based on past practical experience and have the environment and conditions to repeat previous successful projects.

(3) Defined Level (defined ). The development process, including technical work and management work, has been standardized and documented. A sound training system and expert review system have been established. All technical activities and management activities can be controlled, and a common understanding of the process, position, and responsibilities of the project is given.

(4) managed ). Quantitative quality objectives have been set up for products and processes. Productivity and Quality in development activities are measurable. A process database has been created. Project product and process control has been implemented. Predictable process and product quality trends, such as predictive deviations, can be corrected in a timely manner.

(5) optimization level (optimizing ). You can focus on improving the process and adopt new technologies and methods. Provides measures to prevent defects, identify weaknesses, and improve the performance. Statistical data on the effectiveness of the process can be obtained and analyzed to obtain the best method.
