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).
