The name of CMMI is Capability Maturity Model Integration, which is jointly developed by the U.S. Department of Defense, Carnegie Mellon University and the National Defense Industry Association. Its purpose is to help software enterprises manage and improve the software engineering process, and enhance their ability to develop and improve high-quality software on time and within budget. It is based on the idea that we can overcome the difficulties of software development by focusing on building an effective infrastructure software engineering process and continuously improving management norms and processes. CMMI improves organizational processes to provide a single integration framework. The new integrated model framework eliminates the inconsistency of each model, reduces the duplication between models, increases transparency and understandability, and establishes an automated and extensible framework. So as to improve quality and organizational efficiency. CMMI mainly focuses on four processes: cost performance, clear focus, centralization and flexibility.
CMMI3 has only one level, that is, three levels:
CMMILevel 1, degree of completion. Complete the project business objectives assigned by the superior, and strive to achieve very clear project objectives. However, due to the high probability of completing the task, enterprises cannot guarantee that they can still complete the task when implementing similar projects. Enterprise-level execution has great dependence on the implementation of employee projects.
CMMILevel 2, management level. At the management level, the enterprise must prepare the resources and responsibilities for project implementation according to the established procedures and processes, conduct appropriate training, supervision and whole-process control for relevant project implementers, and review with the superior units and processes of the project. The enterprise reflects a series of project management procedures at the secondary level. This series of management measures eliminates the randomness of the company's task completion and ensures the smooth implementation of all projects.
CMMILevel 3, the definition of class. At the class level, enterprises can not only realize a set of project management practices and protect completed projects; In addition, enterprises can institutionalize management systems and processes according to their own specific conditions and their own standard processes. In this way, enterprises can successfully implement different types of projects and the same projects. Become an enterprise and commercial organization with rich culture and scientific management.
CMMILevel 4, quantitative management level. At the level of quantitative management, enterprise project management is systematic, which not only forms, but also realizes digital management. Manage the process and realize quantification and digitization. Through quantitative processing technology, stable and accurate management can be realized, and the quality fluctuation of project implementation can be reduced.
CMMILevel 5, optimization level. Hierarchical optimization is the highest level of enterprise project management. Enterprises not only realize project management by means of informationization and digitalization, but also make full use of possible defects in information materials in the process of implementing commercial projects. Can actively improve the process, apply new technology and optimize the process. Enterprises in CMMI should realize it step by step. Generally speaking, you should start with two. Try to manage. Strive to achieve the last fifth grade of CMMI.
See here, you will know what this means: CMMI3 certification. After passing the CMMI3 certification issued by the rating agency, it is equivalent to one of your diplomas.
