"A cardinal principle of Total Quality escapes too many managers: you cannot continuously improve interdependent systems and processes until you progressively perfect interdependent, interpersonal relationships"

This quote by Stephen Covey stresses the value of interpersonal relationships in order to improve synergistic systems and procedures. He is suggesting that managers need to concentrate on developing strong relationships between individuals in order to accomplish total quality. This is due to the fact that synergistic systems and processes depend on the cooperation of different individuals in order to be successful. Without strong social relationships, it is tough to make development in enhancing these systems and procedures. Therefore, Covey is recommending that supervisors ought to focus on establishing strong relationships in between people in order to achieve overall quality. This is a primary concept of Total Quality that need to not be ignored.
