What’s Process Capability?

Process Capability is a measurement of how well a Process’ Outputs meet Customer Requirements.

Strong Process Capability indicates that a high percentage of Output meets Customer Requirements, while Weak Process Capability means the opposite. Weak Process Capability is usually due to unacceptably high variability of Output that falls outside Customer Requirements.
