• Document a new or improved process and measurement • Use statistical process control (SPC) for validating collection systems • Use SPC to ascertain the repeatability and reproducibility of metrics in an operational environment • Define the control plan and its supporting plans such as communications plan of the improvements and operational changes to the customers and stakeholders, prepare implementation and risk management plan, consolidate cost-benefit, and change management plan • Establish tracking procedures in an operational environment: monitor implementation, validate and stabilize performance gains, and jointly audit the results and confirm the financials • Setup control plans for tolerances, controls, measures, and standard operating procedures • Validate in-control process and benefits for process capability, MSA and Gage R&R, and documentation • Document and the follow-up steps • Exit review
Control PlansSo far, our attempt has been to identify the most important contributing variables of the process. Through the completed five phases, we have been trying to establish the best process model free of all kinds of variations. The method so far enabled us to identify a viable model and helped us to quantify the nature of the relationship between the important variables of the process output. The statistical process control technique can now be employed with considerable effectiveness for monitoring and surveillance of the process. Techniques such as control charts and capability assessment can be used to monitor the process output and detect when changes in the inputs are required to bring the process back to an in-control state.
