2. QUALITY
--Quality Control is the responsibility of the primary installer or fabricator of the material; they are the experts in what they build.
--Quality Assurance is the oversight by the agency of the Quality Control; they want to receive what is specified.
Uses verified QC testing and inspection as acceptance (like when observing the production of a car you want to buy )
--Independent Assurance is the responsibility of the agency to ensure QA and QC are verifiable
Make sure QC and QA testing are compatible and consistent
