SPC, or Statistical Process Control, is primarily a method used in quality control processes that focuses on process monitoring and control through statistical methods. While SPC can be a tool used within quality assurance and process improvement efforts, it does not represent a formal standard specifically designed for software development or testing processes.

In contrast, the other mentioned standards serve as frameworks for evaluating and improving software processes. CMMI (Capability Maturity Model Integration) provides guidelines for process improvement across a project, division, or organization. P-CMM (People Capability Maturity Model) specifically addresses the improvement of the workforce within an organization. ISO 9001 is a globally recognized standard that outlines criteria for a quality management system. Each of these standards aims to enhance the effectiveness and maturity of processes within the software development and testing domains, making them widely recognized in the industry.
