WebMar 27, 2024 · A statistical process control system (SPC) is a method of controlling a production process or method utilizing statistical techniques. Monitoring process behavior, identifying problems in internal systems, and finding solutions to production problems can all be accomplished using SPC tools and procedures.
WebSPC Charts analyze process performance by plotting data points, control limits, and a center line. A process should be in control to assess the process capability. Control Charts are to detect special causes (non-random) of variation that may or may not be within the Control Limits. Every process will have random inherent (common cause) variation.
