Philip B. Crosby, a renowned quality management expert, emphasized the importance of preventing defects rather than detecting and fixing them later. His philosophy centered around the concept of “doing it right the first time” (DIRFT). Here’s a breakdown of his definition of quality:

Conformance to Requirements: Crosby believed that quality is about meeting the established requirements. These requirements include both the product’s technical specifications and the customer’s expectations. When a product or service aligns with these requirements, it achieves quality.

Not as Goodness: Crosby’s definition focuses on objective criteria rather than subjective judgments. Quality is not merely about being “good” but about adhering to specific standards.

Prevention: Crosby’s second absolute emphasizes prevention over appraisal. Rather than inspecting and correcting defects after they occur, organizations should proactively prevent them. Prevention involves robust processes, training, and continuous improvement.

Zero Defects: The third absolute states that the performance standard should be zero defects relative to requirements. In other words, organizations should strive for perfection, aiming to eliminate defects entirely.

Price of Nonconformance: The fourth absolute highlights that measuring quality involves assessing the cost of nonconformance. This cost includes rework, scrap, customer dissatisfaction, and lost opportunities.

In summary, Crosby’s definition of quality emphasizes meeting requirements, preventing defects, and striving for zero defects. It aligns with the principles of Total Quality Management (TQM) and continuous improvement12.
