1. Importance of Control Plan Development
Control plan development is essential in Six Sigma projects for maintaining process improvements, ensuring consistent performance, and preventing regression. By systematically documenting and monitoring key process variables, organizations can sustain improvements and achieve long-term success.
Key Benefits:
Maintains Improvements: A control plan ensures that the improvements made during a Six Sigma project are maintained over time. For example, documenting key process variables and control methods to ensure that a new production process consistently produces high-quality outputs.
Prevents Regression: By continuously monitoring key process variables, a control plan helps prevent regression to previous suboptimal performance levels. For instance, using control charts to monitor process performance and detect any deviations from the target.
Ensures Consistent Performance: A control plan ensures that processes perform consistently by outlining the necessary controls and monitoring methods. For example, specifying regular inspections and testing procedures to ensure consistent product quality.
Enhances Accountability: Documenting responsibilities and monitoring methods in a control plan enhances accountability among team members. For instance, clearly defining roles and responsibilities for monitoring and controlling key process variables.
Example: At General Electric (GE), control plan development is integral to their process improvement initiatives. By systematically documenting and monitoring key process variables, GE can maintain improvements and ensure consistent performance.

2. Steps to Develop a Control Plan
Developing a control plan involves several steps, each crucial for systematically documenting and monitoring key process variables. Following a systematic approach helps in effectively developing a control plan and sustaining improvements.
Step-by-Step Guide:
Step 1: Define Objectives and Scope
- Action: Clearly define the objectives and scope of the control plan, including the specific processes or areas to be controlled. This ensures a focused and relevant approach.
- Example: “Define the objective as maintaining improvements in the assembly line process and the scope as the entire assembly line operation.” Defining objectives and scope helps in focusing the control plan.
Step 2: Identify Key Process Variables
- Action: Identify the key process variables that need to be controlled to maintain improvements. This helps in focusing the monitoring efforts on critical aspects of the process.
- Example: “Identify key process variables such as temperature, pressure, and cycle time in the assembly line process.” Identifying key process variables helps in focusing the monitoring efforts.
Step 3: Determine Control Methods
- Action: Determine the control methods to be used for monitoring and controlling the key process variables. This ensures that appropriate methods are in place to maintain control.
- Example: “Determine control methods such as control charts, regular inspections, and automated sensors for monitoring temperature, pressure, and cycle time.” Determining control methods helps in ensuring appropriate methods are in place.
Step 4: Establish Monitoring Procedures
- Action: Establish the monitoring procedures, including the frequency of monitoring and the tools to be used. This ensures that monitoring is carried out systematically and consistently.
- Example: “Establish monitoring procedures such as hourly temperature checks using thermocouples and weekly inspections of pressure gauges.” Establishing monitoring procedures helps in ensuring systematic and consistent monitoring.
Step 5: Define Responsibilities
- Action: Define the responsibilities for monitoring and controlling the key process variables, including who is responsible for each task. This enhances accountability and ensures that monitoring is carried out effectively.
- Example: “Define responsibilities such as assigning temperature checks to the process operator and pressure inspections to the maintenance technician.” Defining responsibilities helps in enhancing accountability.
Step 6: Develop Response Plans
- Action: Develop response plans for addressing deviations from the target, including the actions to be taken and the responsible individuals. This ensures that deviations are addressed promptly and effectively.
- Example: “Develop response plans such as adjusting the temperature control settings if temperature readings exceed the target range and notifying the supervisor.” Developing response plans helps in ensuring prompt and effective actions.
Step 7: Document the Control Plan
- Action: Document the control plan, including all the identified variables, control methods, monitoring procedures, responsibilities, and response plans. This ensures that the control plan is comprehensive and accessible.
- Example: “Document the control plan in a standard format, including all key process variables, control methods, monitoring procedures, responsibilities, and response plans.” Documenting the control plan helps in ensuring it is comprehensive and accessible.
Step 8: Review and Update Regularly
- Action: Regularly review and update the control plan to ensure it remains relevant and effective. This helps in maintaining control over time and adapting to any changes in the process.
- Example: “Review and update the control plan quarterly to ensure it remains relevant and effective.” Reviewing and updating regularly helps in maintaining control over time.
