I tend to get it mixed up sometimes with tricky questions on quality assurance and [b][b]control quality. I understand QA is about ensuring that the process is followed as planned and using quality control measures to check the processes outlined in the Quality Mgt Plan and QC deals with inspecting deliverables. The word "audit" is used for QA and inspection for QC.
Could someone explain and provide an example (for the bold and underlines section) from the PMBOK 5th edition under QA. The word inspection is used for work in process items (why not audit again since it is the process that is being examined).
"The quality assurance process implements a set of planned and systematic acts and processes defined within the project’s quality management plan. Quality assurance seeks to build confidence that a future output or an unfinished output, also known as work in progress, will be completed in a manner that meets the specified requirements and expectations. [b]Quality assurance contributes to the state of being certain about quality by preventing defects through the planning processes or by inspecting out defects during the work-in-progress stage of implementation."
