Statistical Process Control (SPC) is a method used to monitor and control quality within processes, particularly in manufacturing and service delivery, by employing statistical methods. SPC aims to distinguish between natural (common cause) variation and variation due to specific changes or events (special cause), allowing for timely improvements and sustained quality. The control chart, a pivotal tool in SPC, visually displays data over time alongside a central line of upper and lower control limits, enabling the identification of trends that indicate changes in process stability.

The application of SPC is significant in maintaining the efficiency of processes by ensuring predictable output quality, thereby minimizing waste and defects. It measures performance and detects whether implemented changes lead to sustainable improvements.

SPC is used extensively in healthcare to monitor treatment outcomes, laboratory turnaround times, and patient satisfaction, among other metrics. It is also applicable in research settings to analyze data variation over time, contributing to the quality improvement of studies. In healthcare, SPC charts have been instrumental in monitoring infection rates, with changes such as modifying surgical site preparation techniques shown to reduce infection rates significantly. Similarly, test turnaround times have been optimized in laboratory settings by analyzing data for special cause variations and making process adjustments accordingly.

SPC provides a robust framework for understanding and improving processes in various domains, ensuring quality enhancements are based on reliable, data-driven insights. It empowers teams to make informed decisions, avoid unwarranted changes, and focus on interventions that deliver real improvements.
