Engineering activities inspection involves themeasurements, tests, and gauges applied to certain characteristics in regard to an object or activity. The results are usually compared to specified requirements and standards for determining whether the product is to the customer’s satisfaction. Inspections are usually non-destructive. Whenever work is done or a product or part is made—whether it is a piece of hardware manufactured on the assembly line, a memo typed by a secretary, or code developed by software programmers—it should be inspected to see that it fulfills the requirements and specifications. This is certainly a wise business practice. Some companies accept a certain failure rate, while others try to correct the problems they see from their inspection. Inspecting and then correcting will save company money.
