What does statistical process control (SPC) utilize to monitor processes?

Statistical process control (SPC) relies on statistical methods to monitor and control processes. This approach uses various statistical tools, such as control charts, to track process performance over time, identify trends, detect variations, and ensure that processes operate within predetermined limits. By applying statistical techniques, operators can distinguish between common cause variations (inherent to the process) and special cause variations (indicative of issues). This enables proactive adjustments to maintain the desired quality and efficiency in manufacturing operations.

The use of statistical methods provides a solid foundation for data-driven decision-making, allowing for systematic improvements and maintaining high-quality standards in production processes.
