Philip B. Crosby's principle emphasizes 'doing it right the first time' to foster continuous improvement despite inevitable mistakes. He defines quality as conformance to requirements with a focus on defect prevention and maintains that the ultimate standard is achieving zero defects. Quality is measured by the cost of nonconformance to these standards.
