Control Plan

Living document that describes the systematic approach for controlling a process, including what to measure, how to measure it, measurement frequency, who is responsible, and what to do when results are out of specification. Updated as result of 8D D6 and D7 to incorporate lessons learned and prevent recurrence. Different from work instructions (how to do the work) by focusing on verification and reaction plans. Essential element of automotive quality systems (APQP, IATF 16949) and Six Sigma Control phase.
