Chapter 6, "EMC and PCB Design," Chapter 9, "Design for Test," and Chapter 15, "Hardware Reliability and Failure Analysis."

12.2 Testing Philosophies Testing can be considered both a value added and a non-value added part of the manufacturing process. When testing is used to monitor the manufacturing process and feed defect data back to help tune the process, it is considered to be value added. Testing is also considered to be value added when it provides a quality (defect-free, functionally performing unit) product to the customer. From a business case perspective, the overall cost to test must be less than the overall cost to manage defective product at the customer site. Non-value added testing includes redundant testing and testing that does not contribute to the overall quality to the customer.
