Six Sigma Control Plans / Dynamic Control Plans

Control plans are an important component of Six Sigma methodology that are used to ensure that a process remains in control and meets customer requirements. A control plan is essentially a document that outlines the steps that need to be taken to maintain process stability and consistency, and it includes details on the key process inputs, outputs, and measures that will be monitored.

Dynamic control plans are an extension of traditional control plans that take into account the dynamic nature of processes. In dynamic control plans, the control limits are adjusted based on the variability observed in the process over time. This means that the control limits are not fixed, but rather are adjusted based on the process performance data. Dynamic control plans are particularly useful in processes that are subject to change or have a high degree of variability.

The key steps in developing a control plan include:

Identify the process to be controlled
Define the process inputs, outputs, and measures
Establish target values and specifications for the process measures
Determine the frequency and method of data collection
Establish control limits based on historical data or industry standards
Develop a response plan for out-of-control situations
Implement the control plan and monitor the process performance
Dynamic control plans add an additional step to the process, which involves analyzing the process performance data and adjusting the control limits as needed to maintain process stability and meet customer requirements. This approach allows Goodyear Rubber to be more responsive to changes in the process and to continuously improve their operations.
