At the Control Phase, you begin to control the new system by implementing the ongoing improvement measures. The aim is to keep the problem from recurring. To be able to do that, your organization must learn to institutionalize the improved system through the modified policies, procedures, operating instructions, and other management systems. You need to specify process control method; establish on-going controls for the process based on prevention of special cause variation using statistical process control techniques; document the improvement processes; and record all the processes/steps in improvement phase using the decision tree
and reaction plan.
Below are the key concepts for the Control Phase.
