Step 1: Identify Ajay's main objective.
Since Ajay wishes to retire in five years while leaving a strong legacy, his focus should be on long-term institutional strengthening, not on short-term fixes or passivity.
Step 2: Evaluate the activities.
- (1) Do nothing: This is completely unsuitable because it will damage Ajay’s legacy.
- (2) Set a future direction: This is the first and most important step. A clear vision ensures stability and purpose for the organization.
- (3) Benchmarking performance: After setting direction, Ajay must compare with industry best practices to maintain competitiveness.
- (4) Empower senior consultants: Once standards are set, empowering leaders ensures sustainability after Ajay’s retirement.
- (5) Infuse fresh thinking: Finally, bringing in outsiders is valuable but comes after internal direction and empowerment.
Step 3: Order the activities.
The logical sequence is:
\[
2 \; ⇒ \; 3 \; ⇒ \; 4 \; ⇒ \; 5
\]
\[
\boxed{2, 3, 4, 5}
\]
