“More correctly, the process of inspecting software to improve its quality is at best misguided and at worst downright stupid.”

Testing is evil

Page 3: Testing, specification over verification

“Quality comes not from inspection, but from improvement of the production process..”

“Inspection does not improve quality, nor guarantee quality. Inspection is too late. The quality, good or bad, is already in the product. As Harold F. Dodge said, ‘You can not inspect quality into a product.’.”

“Every company has a quality control department. Unfortunately, quality control departments have taken the job of quality away from the people that can contribute most to quality”

Quotes from “Out of the Crisis”

W. Edwards Deming
