Step 1: Identify the concept being tested.
The question asks how Decentralisation gives relief to top management, another key benefit of decentralisation.
Step 2: Explain the concept.
When authority is decentralised, routine and departmental decisions are handled by middle and lower-level managers, leaving top management with only the most important, strategic matters.
Step 3: Explain the benefit to the top executives.
With day-to-day operational issues taken off their plate, top managers carry a lighter administrative workload and are freed from having to supervise every small decision directly.
Step 4: Final answer.
Decentralisation gives relief to top management because routine decisions are delegated to lower levels, allowing top executives to spend their time and energy on long-term planning, strategy and growth opportunities instead of routine supervision.
