Final answer:
Technical skills are considered the least important for top managers, according to Robert Katz, as they focus more on conceptual and human skills.
Step-by-step explanation:
According to Robert Katz, the managerial skills LEAST important to a top manager are technical skills. Katz's model of managerial skills includes three essential types: conceptual skills, which involve the ability to understand complex ideas and the organization as a whole; human skills, which pertain to the ability to interact effectively with people; and technical skills, which relate to expertise in a specific field. For top managers, the broader view and strategic thinking provided by conceptual skills, coupled with the ability to manage and motivate people using human skills, are more critical than the specialized technical knowledge that is often more important at lower levels of management.
