Cooperation is required to improve quality and to implement quality management.

Modern quality-management frameworks (e.g., ISO 9000 family, IEEE Std 730) and the classical teachings of Deming, Juran and Crosby all state that quality improvement cannot be achieved by isolated functions. Sustained quality improvement and the effective operation of a quality-management system require the active cooperation of “people at all levels” and “all relevant functions” in the organization. Hence cooperation is not optional but required to both improve quality and to implement/maintain a quality-management system. Why the other option is wrong:
• False – would contradict the fundamental “engagement of people” principle in ISO 9000 and the cross-functional collaboration requirements found in IEEE 730; without cooperation, quality initiatives consistently fail (as documented in empirical studies and university coursework).

1. ISO 9000:2015, Quality management systems — Fundamentals and vocabulary, Clause 2.3.6 “Engagement of people”, bullet a: “People at all levels … must be involved and cooperate to enhance the organization’s capability to create and deliver value.”

2. ISO 9001:2015, Clause 5.1.1 b & f: Top management shall “promote a customer focus throughout the organization” and “communicate the importance of effective quality management,” both of which presuppose inter-functional cooperation.

3. IEEE Std 730-2014, §5.2 “SQA Activities”: “The SQA Group shall work with project management, development, test, configuration management and other involved groups…” (explicit requirement for cooperation).
