According to total quality control philosophy, all areas of a company must be involved in what?

The total quality control philosophy emphasizes that quality is not the sole responsibility of a dedicated quality department. Instead, it involves an organizational-wide commitment to enhancing quality in all aspects and departments of the company. This holistic approach means that every employee, from top management to frontline workers, plays a critical role in the quality effort.

By fostering a culture of quality, organizations can ensure that products and services meet or exceed customer expectations, drive continuous improvement, and create a competitive advantage. Quality efforts should encompass every process and function within the organization, ensuring collaboration and communication among various departments, which ultimately leads to higher customer satisfaction, reduced costs, and improved performance.

The focus on quality efforts aligns with the core principles of total quality management (TQM) and continuous improvement methodologies such as Six Sigma. This philosophy promotes the idea that quality is a never-ending journey involving the collective commitment of all employees.
