Capability Maturity Model Integration (CMMI) Cheatsheet: A Comprehensive Guide

Introduction: What is CMMI and Why It Matters

The Capability Maturity Model Integration (CMMI) is a process improvement framework that helps organizations streamline process improvement and encourage productive, efficient behaviors. Originally developed by the Software Engineering Institute (SEI) at Carnegie Mellon University, CMMI has evolved from the original Capability Maturity Model (CMM) into a comprehensive approach for developing and refining an organization’s development processes across multiple disciplines. CMMI provides organizations with the essential elements of effective processes, which will improve performance across projects, divisions, and the entire organization.

Core CMMI Concepts

Process Areas

• Process Areas (PAs): Collections of related practices in a particular area that, when implemented collectively, satisfy goals for improvement in that area
• Generic Goals: Apply to multiple process areas and describe the institutionalization of processes
• Specific Goals: Apply to a specific process area and describe unique characteristics of that area
• Generic Practices: Activities that ensure proper implementation and institutionalization of the process areas
• Specific Practices: Activities expected to result in achievement of specific goals

Representation Types

• Staged Representation: Focuses on organizational maturity; provides a proven sequence of improvements, each serving as a foundation for the next
• Continuous Representation: Focuses on capability levels within individual process areas; allows organizations to improve different processes at different rates

Maturity vs. Capability Levels

• Maturity Levels (ML): Used in staged representation to characterize organizational improvement relative to a set of process areas
• Capability Levels (CL): Used in continuous representation to characterize improvement within individual process areas

  • Causal Analysis and Resolution (CAR)

• Key Practices:

  • Select and deploy incremental and innovative improvements
  • Identify root causes of defects and problems
  • Evaluate, pilot and deploy improvements
