CMII: Code of Integrity [Visual Explainer]

What is CMII?

CMII, or Configuration Management II, emerged in the 1980s amid increasing complexities and challenges in the manufacturing industry, which was especially evident in aerospace and defense

Traditional Configuration Management Limits

The Institute of Configuration Management, now known as Institute for Process Excellence (IpX), developed CM2 to address limitations traditional config management had scaling change management and product complexity.

Industry Standard for Digital Thread

The recognized industry standard for digital thread implementations, CMII “bridges interoperability gaps between design and data flow analysis tools with a common language.”

Focus on Change

Efficient change management is an essential element of the CMII model. During any product or system change, CMII tracks the associated changes carefully to ensure they won’t disrupt other components.

Detailed Documentation

Every little detail about a product or system throughout its lifecycle must be documented. That includes info on materials used, assembly, maintenance, and any changes throughout the product lifecycle.

Communication is Key

CMII prioritizes communication among everyone involved in developing and maintaining a product, including engineers, designers, and any decision makers.


CMII sets standards for configuration management throughout the lifecycle. The more everyone follows the defined process, the smoother operations will run.

Quality and Compliance

CMII helps ensure products are developed according to government regulations and industry standards. This is especially important for highly regulated industries like aerodef, automotive manufacturing, transportation, and medical device.

CMII Systems

A number of systems in a typical manufacturing tech stack supports CMII principles and practices, including PLM (product lifecycle management), project management software, DMS (document management system), QMS (quality management system) as well as a host of standalone tools.

Structured Approach

To summarize, CMII is especially important for complex or highly important products and systems. The structured approach helps ensure steps are taken correctly, there is continuous improvement, safety is paramount, and errors and delays are minimized.
