SPS, or Statistical Process Control, is a method used in quality control to monitor and control a process through statistical analysis. It helps organizations ensure that their processes operate efficiently and produce products that meet quality standards. By using control charts and other statistical tools, SPS identifies variations in processes, allowing for timely adjustments to maintain quality. In manufacturing and service industries, SPS plays a crucial role in reducing waste and improving productivity. It involves collecting data from processes, analyzing it, and making informed decisions based on the results. This proactive approach helps organizations maintain consistency and enhance customer satisfaction.
