According to the PMBOK Guide, specifically within the Project Quality Management knowledge area, Perform Quality Assurance (often referred to as Manage Quality in newer editions) is the process of auditing the quality requirements and the results from quality control measurements to ensure that appropriate quality standards and operational definitions are used.
* The Focus of Quality Assurance: Unlike Quality Control, which focuses on the product or the output, Quality Assurance focuses on the process. It is an executing process that uses data from the controlling process to confirm that the project is following the " rules " and standards set during the planning phase.
* Operational Definitions: These are the specific descriptions of a project or product attribute and how the quality control process will measure it. Quality Assurance ensures these definitions are being applied correctly during the work.
* Key Tool - Quality Audit: A structured, independent process to determine if project activities comply with organizational and project policies, processes, and procedures. The objective of a quality audit is to identify inefficient or ineffective policies and processes being used on the project.
Analysis of Other Options:
* A. Plan Quality: This is the process where you identify which quality standards are relevant to the project and determine how to satisfy them. It creates the standards, but it is not the process that ensures they are being used during execution.
* C. Perform Quality Control: This process is focused on monitoring and recording results of executing the quality activities to assess performance and recommend necessary changes. It is concerned with finding defects in the final deliverables rather than ensuring process standards.
* D. Total Quality Management (TQM): This is an organizational philosophy and a management approach to long-term success through customer satisfaction. While TQM influences project quality management, it is not a specific process within the PMBOK Guide framework.
