Who is responsible for just one organizational activity?

• A. Functional manager
• B. General manager
• C. Top managers
• D. Interpersonal Roles

Answer: (A)

The main idea is specialization within an organization: a single function is owned by a dedicated manager. A functional manager is the person responsible for one specific function, such as finance, marketing, or production. They oversee planning, staffing, budgeting, and performance for that function and coordinate with other parts of the organization as needed. This contrasts with a general manager who spans several functions, a top manager who guides the whole organization, and interpersonal roles which describe the kinds of interactions a manager engages in rather than a single activity owner. So, the one responsible for just one organizational activity is the functional manager.
