1. ISO 9000: "Degree to which a set of inherent characteristics fulfills requirements." The standard defines requirement as need or expectation.

2. Six Sigma: Number of defects per million opportunities

3. Philip B. Crosby: "Conformance to requirements." The requirements may not fully represent customer expectations; Crosby treats this as a separate problem.

b. "The loss a product imposes on society after it is shipped."This definition of quality is based on a more comprehensive view
