Before anything else, it’s crucial to understand and prioritize the needs of your customers. This step ensures that the strategic plan aligns with customer expectations and requirements.

Development of quality goals and strategies by upper management: Once customer needs are clear, upper management should define quality goals and strategies. These goals guide the organization toward achieving excellence and meeting customer expectations.

Translate strategies into the annual business plan: After setting quality goals, the next step is to translate broader strategies into actionable plans. The annual business plan outlines specific initiatives, targets, and resource allocation to achieve the strategic objectives.

Implementation of action by line departments: Finally, line departments execute the planned actions. They put the strategies into practice, monitor progress, and make necessary adjustments to ensure successful implementation.

Therefore, the correct order is C. 3, 1, 4, 21.
