Concept:
• Top Level Management: Consists of Board of Directors, CEO, Chairman, etc. They focus on overall objectives, corporate strategy, and the organization's interface with the environment.
• Middle Level Management: Consists of Departmental Heads (Production, Marketing, etc.). Their primary job is to coordinate departmental activities and cooperate with other departments.
Step 1: Examine the strategic roles in the options
Options (B), (C), and (D) involve "overall goals," "strategies," "welfare and survival," and "business environment analysis." These are high-level, long-term strategic functions that only Top Level Management can perform.
Step 2: Examine the operational/coordination role in Option (A)
Option (A) discusses "cooperating with other departments." While Top Level management coordinates the whole organization, the specific duty of day-to-day inter-departmental cooperation is assigned to the Middle Level Management (departmental heads).
Step 3: Validate using standard management theory
According to the hierarchy of management, the middle level is responsible for implementing the policies of the top level and ensuring that different departments work together harmoniously to achieve the sub-goals.
