Capability/Maturity Levels - Key Measurement Concept

Capability and Maturity Levels share the same characteristics in terms of the transition from lower to the next.

When the enterprise/process becomes managed from initial chaotic state, it achieves level 2 capability/maturity.

Within level 2/3/4, the progress transition is  to proactively managed (3), then to proactive managed with empirical measurements (4).

Finally when all focus is in optimization, it reaches to the ultimate level 5.
