First of all, quality meets the requirements: all activities necessary for running an organization, producing a product or service and dealing with customers must meet this requirement. If management wants employees to do things right the first time, then the organization must clearly tell employees what things are and help employees achieve this goal through leadership, training and creating a cooperative atmosphere.

Second, the quality system is prevention: the quality system is prevention, and the cause of the error is eliminated before it appears. Crosby believes that training, discipline, role models and leadership can produce preventive effects. The management must make up its mind and make continuous efforts to create a prevention-oriented working environment.

Third, the working standard is zero defect (get things right the first time): the "almost" quality attitude is intolerable in crosby's method. The cost of mistakes is too high for us to ignore. Leaders must help all employees achieve their goals through training and providing resources such as time and tools.

Fourthly, the measure of quality is "the cost of nonconformity": "nonconformity" is a management tool used to diagnose the efficiency and effectiveness of an organization.
