Answer:
The correct answer is (C) direct supervision by the upper echelon.
Step-by-step explanation:
In Mintzberg's organizational structures, the simple structure achieves coordination through direct supervision by the upper echelon. In this type of structure, decision-making authority is concentrated at the top, usually with the founder or owner of the organization. The upper echelon directly supervises and controls the work of employees, providing guidance, instructions, and oversight. This direct supervision helps ensure coordination and alignment of activities within the organization. It is a common approach in small businesses or startups where the founder has a hands-on approach and maintains close control over operations.
