What Is a Capability Maturity Model?

A Capability Maturity Model (CMM) is a structured framework—originating at the SEI for the U.S. DoD—that describes how consistently an organization can perform a class of work, and the evolutionary path for improving that capability.

Definition

Shared Language for Progress

Each level defines the behaviors, artifacts, and controls you must demonstrate before moving on. It replaces fuzzy statements like "be better with AI" with observable, auditable practices.

Structure

Ordered, Measurable Levels

  • Level 1: initial, inconsistent wins.
  • Level 2-3: defined processes + governance.
  • Level 4-5: data-driven optimization + innovation.
Why it matters

Guides Investment & Accountability

Executives use CMMs to align talent, tooling, and budget. Teams know what "good" looks like, and leaders can prove improvements with evidence instead of anecdotes.

How we'll use it next: We'll adapt this pattern to agentic workflows so each EM can diagnose current behavior, prescribe the next level, and measure frontier activation with the same rigor we use in security or reliability CMMs.
