Which principle of quality management emphasizes a systematic, process-based approach and defined interactions between processes?

• A. The customer focus.
• B. The plan-do-check-act cycle.
• C. The supplier management principle.
• D. The process approach.

Answer: (D)

The process approach is about organizing and managing activities as a network of interrelated processes with clear boundaries, inputs, outputs, owners, and interfaces. By understanding how each process works and how they connect with others, an organization can achieve more consistent results, better coordination across functions, and ongoing improvement. This view treats the quality system as a system of processes that interact in defined ways, which is why it best fits the idea of a systematic, process-based approach with defined interactions between processes. The other concepts focus on specific aspects—customer focus on meeting needs, the PDCA cycle as a method for improvement, and supplier management for external inputs—but they don’t capture the structured look at processes and their interconnections that the process approach provides.
