This capability maturity model includes the six elements of infrastructure focused on Sarbanes-Oxley project-to-process management.

The capability maturity model describes a maturity curve on these capability levels: INITIAL, which describes a poorly aligned function with non-documented strategies, manual management processes, lack of integrated systems and heavy reliance on spreadsheets/manual documents; REPEATABLE, which describes a loosely aligned function supported by informal policies applied to processes performed by personnel with mixed skill levels; DEFINED, which describes a strategic management structure in place with well-defined processes supported by an organized and highly trained team; MANAGED, which describes a function aligned with the organizational strategic plan and personnel; and OPTIMIZED, which describes a management process performed at an optimal level with best practices in full use.

In this sample, an OPTIMIZED organization’s controls are preventive and system-based.

The capability maturity model is a framework that describes an improvement path from an ad-hoc, immature process to a mature, disciplined process focused on continuous improvement. The CMM defines the state of a process using a common language that is based on the Carnegie Mellon Software Engineering Institute Capability Maturity Model.
