Quality control involves monitoring specific project results to determine if they comply with relevant quality standards, and identifying ways to eliminate causes of unsatisfactory results. It should be performed throughout the project. Project results include both product results, such as deliverables, and project management results, such as cost and schedule performance. Quality control is often performed by a Quality Control Department or similarly titled organizational unit, but it does not have to be. The project management team should have a working knowledge of statistical quality control, especially sampling and probability, to help it evaluate quality control outputs. Among other subjects, the team may find it useful to know the differences between: Prevention (keeping errors out of the process) and inspection (keeping errors out of the hands of the customer). Attribute sampling (the result conforms, or it does not) and variables sampling (the result is rated on a continuous scale that measures the degree of conformity). Special causes (unusual events) and random causes (normal process variation). Tolerances (the result is acceptable if it falls within the range specified by the tolerance) and control limits (the process is in control if the result falls within the control limits).

Information about the planned or expected results (from the project plan) should be available along with information about the actual results. .2 Quality management plan. The quality management plan is described in Section 220.127.116.11. .3 Operational definitions. Operational definitions are described in Section 18.104.22.168. .4 Checklists. Checklists are described in Section 22.214.171.124. 8.3.2 Tools and Techniques for Quality Control .1 Inspection. Inspection includes activities such as measuring, examining, and testing undertaken to determine whether results conform to requirements. Inspections may be conducted at any level (e.g., the results of a single activity may be inspected, or the final product of the project may be inspected). Inspections are variously called reviews, product reviews, audits, and walkthroughs;...
