The goal of AV9000:2011 is to lay out the requirements for a Quality Management System for the AV
industry designers and installers, assuring projects are delivered complete, on time, with “zero defects”,
and as the customer expected. A battery of tests to be performed at various milestones throughout an
AV project is referenced and is included in Section Two: Measurements.  Please see the full document here.
