What is a Six Sigma Control Plan and how does it work?

The Lean Six Sigma control plan format is a written description of the process. A control plan example would be that it describes the steps required to maintain a process or device at its current level. Each step is described in detail and the parameters are to be monitored so that deviations or variations are not made from the average performance of the batch of products.

Two segments make up a Lean Six Sigma control program.

  • process summary is a tool that allows process monitoring. It allows visibility, review and action on all process outputs within an organisation.
  • A tool called process management plan is used to control process. This control plan example creates feedback loops that take action to keep the process under constant control. You can change equipment, materials, or throughput without affecting the quality and efficiency of the process with a good process control plan.

Summary of Process Management

A process management summary is used for gathering all critical-to quality outputs (or CTQs), for a process, department, division or company. You can roll the summary up to any level your company requires to monitor, review, and take actions to improve business performance and process quality. Each time you add the Lean Six Sigma project’s CTQs to your summary, This summary’s administrative section is used to identify organizational areas being discussed. It also includes the revision level and date. The summary’s main body is the place where it is most useful. This provides sufficient information for anyone to see the status of downstream processes and their relationship to it.

The Process Control Plan

The process control plan format is a companion document to the process management summary. The process control plan allows you to focus on the Xs that are the inputs to your process. The formula Y = (x) defines the inputs. These are the critical Xs that the Lean Six Sigma Project has determined. A control plan example is that the CTQs can be placed on a process control program.

When done correctly, the process control plan creates a complete picture of all inputs and outputs for a single process.

Why should you use a Control Plan

The Lean Six Sigma Control Plan format provides a single point of reference for understanding the process’s specifications, characteristics, and standard operating procedures (or SOPs). You can use the Control Plan to delegate responsibility and assign accountability for each activity. This ensures smooth execution and long-term sustainability.

A well-designed control program can prevent negative business consequences from process flaws and process deterioration. It helps process and product owners to track and correct performance of Key Performance Input Variables and Key Performance Output Variables.
