Statistical Process Control (SPC) is a systematic methodology within quality control that applies statistical methods to monitor and control a process. A process is defined as any set of activities that transforms inputs into outputs, such as manufacturing a product or performing a service. Its core purpose is to ensure that the process operates stably and efficiently, consistently producing outputs that conform to specified standards, which are the predefined quality requirements or specifications. SPC functions by continuously collecting data from the process over time and subjecting it to statistical analysis to understand and manage process variation. There are two primar....
