Control Plan Methodology

A control plan is a written description of the systems applied in minimizing the processes and product variation. Its principal intent is to provide a structured approach of the design, selection, and implementation of the system’s value-added controls. 

This may be applied to a group of products as long as they are produced at the same source. Sketches may be provided for visual purposes. 

A control plan is a living document that must be preserved throughout the product life cycle. It guides manufacturing to control the process and assure excellent product quality.

It is important to fully understand the process for it to be effective and successful. The team must utilize all information to obtain a better understanding of the processes.

There are certain benefits in implementing a control plan such as reduction of wastes, improvement on product quality, proper allocation of resources to satisfy customers, and identification of changes. 

Different types of processes can lead to challenges and opportunities. The processes are related to the sources of variation and other external factors. 

There are different ways to analyze processes such as the Cause and Effect, Design of  Experiments, and Fault Tree Analysis.
