SPM, or Statistical Process Control, is a method used in quality management to monitor and control a process through statistical techniques. It helps organizations ensure that their processes operate efficiently and produce consistent results. By analyzing data collected from various stages of production, SPM identifies variations that may indicate potential issues, allowing for timely interventions. In SPM, tools such as control charts and process capability analysis are commonly used. These tools help visualize data trends and assess whether a process is stable and capable of meeting specifications. Implementing SPM can lead to improved product quality and reduced waste in manufacturing and service industries.
