软件成熟度模型

1) Initial. The software process is characterized as ad hoc, and occasionally even chaotic. Few processes are
defined, and success depends on individual effort and heroics.
2) Repeatable. Basic project management processes are established to track cost, schedule, and
functionality. The necessary process discipline is in place to repeat earlier successes on projects with similar
applications.
3) Defined. The software process for both management and engineering activities is documented,
standardized, and integrated into a standard software process for the organization. All projects use an
approved, tailored version of the organization's standard software process for developing and maintaining
software.
4) Managed. Detailed measures of the software process and product quality are collected. Both the software
process and products are quantitatively understood and controlled.

5) Optimizing. Continuous process improvement is enabled by quantitative feedback from the process and
from piloting innovative ideas and technologies.
