What are the contribution of Philip b Crosby in total quality management?

uQuality means conformance to requirements, not elegance

•Either you meet the requirements or not

•Determine requirements up front, and very carefully

uThere is no such thing as a "quality" problem

•There are accounting, mfg, design problems

•Quality originates in those depts., not in QC

uThere is no "economics of quality"
