Step 1: Identify the key facts in the scenario.
A team is described as highly skilled, meaning individual talent is not the problem. However, they lack unity in action, meaning their efforts are scattered and not aligned. The manager holds meetings to ensure all departments work toward a common objective.
Step 2: Understand what the problem represents.
The absence of unity in a group of capable individuals is a coordination problem. Each department may be performing well in isolation, but they are not working together as a single, unified force.
Step 3: Understand the manager's role here.
The manager uses meetings, a form of directing, to communicate shared objectives and synchronize the work of all departments. This is not just about giving orders; it is about creating a common thread that binds all individual actions together.
Step 4: Identify which importance of directing this reflects.
Directing has several recognized importances: initiating action, integrating employees' efforts, motivating employees, facilitating change, and providing stability. The specific importance here is "Integrating employees' efforts," since the manager is weaving the separate work of different departments into one harmonious whole.
Step 5: Confirm with management theory.
Integration of effort is a primary reason why directing is considered the heart of management. Without it, even the most skilled team operates as a collection of individuals rather than as a cohesive unit working toward a single goal.
Step 6: State the conclusion clearly.
The manager's action of aligning all departments toward a common objective through meetings reflects the importance of directing in integrating diverse individual efforts.
\[ \boxed{ \text{Directing integrates employees' efforts} } \]
