Understanding maturity levels
Maturity runs 0 to 5, from None to Optimized. Knowing each level keeps your scoring consistent and honest.

Maturity describes how well a capability is performed, not whether you own a tool for it. Forest uses a six-point scale, 0 through 5, applied to every capability you assess.
The scale
0, None. The capability is not performed in any meaningful way.
1, Initial. It happens, but ad hoc and reactive, depending on individuals.
2, Managed. It is performed with some consistency, though not formally defined.
3, Defined. It follows a documented, standardized process across the organization.
4, Quantitative. It is measured with metrics and managed against targets.
5, Optimized. It is continuously improved using data and feedback.
How to choose a level
Score the capability as it actually operates today, not as the policy says it should. A documented process that nobody follows is closer to Initial than Defined. Owning an advanced tool does not earn a high score if the capability around it is inconsistent.
Use target maturity to express intent. The distance between current and target is the gap, and combined with criticality it sets priority. See What CAMP is for the priority formula.
Most capabilities should not target level 5. Aim for the maturity the capability needs given its criticality, not the maximum on the scale.
Why consistency matters
Because scoring is deterministic, consistent maturity judgments produce trustworthy results. If different teams interpret the levels differently, your scores drift. Agree on what each level means before you assess, then apply it the same way every time. Ready to score? See Completing your first baseline.
