Answer:
Halima is practicing "Strength-based management".
Step-by-step explanation:
Strength-based management is a management method that focuses on the strengths (or positive attributes) an employee posseses, rather than his/her weaknesses. The weaknesses are not completely ignored and efforts are usually made to improve on them.
Halima chooses to focus on her strength, which is organizing events. She also focuses on her immediate subordinate's strength, which is public speaking.
This means Halima is practicing "Strength-based management".
