The objective of SPC is to detect assignable cause variations versus normal random variations in the process. SPC involves collecting data on a process over time and using statistical methods to analyze the data to determine if the process is in control (i.e., it is producing products with consistent quality) or if there are assignable causes of variation that need to be addressed. SPC is used to monitor the performance of a process and make adjustments as necessary to ensure that it is producing products that meet specifications. SPC is not used to determine whether a batch of raw materials or finished goods should be accepted or rejected, nor is it used to identify variable versus attribute measures.
