(15m) There is a certain amount of confusion shown in forum and class questions about the difference between Quality Assurance and Quality Control. Brian Weeks brings some clarity to this topic as well as discussing testing and retesting options.
Part of the confusion comes from the difference between how other contracts handle these two types of testing compared to the MMCD. Other contracts often have the Owner engage and pay one or more testing firms to do Q/A. These firms work concurrently with the Contractor, but report directly to the Owner. As Brian will discuss, the MMCD handles testing differently, with the Contract Administrator (or C.A. for short) receiving Q/A test reports from the Contractor and reporting back to the Owner.
Under the MMCD, the Owner specifies tests to be done for its own reassurance that the work is meeting the contractually required standards. These tests are part of the Contract requirements and the Contractor is obliged to perform them, or arrange for them to be performed during the course of the work.
