Which document is a critically important description of the activities, tools, and procedures needed to control a process delivering a service or product, with the objective of minimizing variation?

• A. Quality Management Plan, or QM Plan
• B. Quality Assurance Plan, or QA Plan
• C. Quality Control Plan, or QC Plan
• D. Quality Audit Plan

Answer: (C)

The essential idea here is controlling the process itself to keep outputs consistent. That control is spelled out in the Quality Control Plan, which describes the specific activities, tools, and procedures used to monitor and regulate the process and its products or services. It includes what will be controlled, how measurements and inspections will be performed, the acceptance criteria, sampling plans, data collection and analysis methods (such as control charts or process capability studies), who is responsible, when controls occur, and what actions are taken if results fall outside tolerances. This plan operationalizes quality at the process level to minimize variation and ensure consistent delivery. A Quality Management Plan outlines the broader approach to achieving quality across the project or organization, setting objectives and responsibilities but not detailing the day-to-day control activities. A Quality Assurance Plan emphasizes preventing defects by improving processes, focusing on process quality and audits rather than the specific control steps for a given process. A Quality Audit Plan centers on planning and conducting audits of the quality system and processes, not on describing how to control a process to reduce variation.
