Step 1: Identify the concept being tested.
The question asks how Decentralisation leads to quick decision-making, one of the key benefits of decentralisation.
Step 2: Explain the concept.
Decentralisation pushes decision-making authority down to the managers who are closest to where the actual problem or opportunity arises, instead of keeping it locked at the top.
Step 3: Explain how this speeds up decisions.
Since lower-level managers do not have to wait for approval from the top for routine or departmental matters, they can act as soon as an issue comes up. This removes the delay that would otherwise be caused by passing the matter up and down a long chain of command.
Step 4: Final answer.
Decentralisation leads to quick decision-making because authority is placed at the point of action itself, so managers can respond to problems immediately without waiting for approvals to travel up and down the hierarchy.
