Control phase
What is a control plan in Lean Six Sigma?
A control plan turns an improved process into a repeatable operating routine, with clear measures, ownership and reaction rules.
A control plan turns an improved process into a repeatable operating routine, with clear measures, ownership and reaction rules.
A control plan is the operational document used in the Control phase of DMAIC to define what will be measured, how often, by whom, against which limits and what action follows if performance moves out of control.
They overlap, but a Lean Six Sigma control plan normally documents the characteristic, specification, measurement method, frequency, owner and reaction plan in one operational document.
The process owner normally owns the control plan after handover, with named operators or team members responsible for individual checks.
It is complete when every critical measure has a clear method, frequency, owner, limit and reaction plan, and the process owner has accepted the handover.
