CISSP考试指南笔记：8.4 能力成熟度模型

Capability Maturity Model Integration (CMMI) is a comprehensive, integrated set of guidelines for developing products and software.

CMMI describes procedures, principles, and practices that underlie software development process maturity.

The five maturity levels of the CMMI model are

• Initial Development process is ad hoc or even chaotic.
• Repeatable A formal management structure, change control, and quality assurance are in place.
• Defined Formal procedures are in place that outline and define processes carried out in each project.
• Managed The company has formal processes in place to collect and analyze quantitative data, and metrics are defined and fed into the process-improvement program.
• Optimizing The company has budgeted and integrated plans for continuous process improvement.Capability maturity models (CMMs) are used for many different purposes, software development processes being one of them.
