Final answer:
The mix of managerial skills needed by a manager varies depending on their level within the organization, with technical skills being key for first-line supervisors and conceptual skills gaining importance in top management roles.
Step-by-step explanation:
The correct answer to the question concerning the relationship between managerial skills and managers' activities is that the mix of skills required of a manager depends on the level of management at which he or she works. This true statement reflects the variation in skill sets that are needed at different management levels within an organization.
At the level of a first-line supervisor, technical skills are often most important because this individual is closely involved in day-to-day operations and processes. At higher levels, such as top management, conceptual and diagnostic skills become increasingly significant as the focus of the role transitions to strategy, vision, and broad organizational issues. Interpersonal skills, while important at every level, are especially crucial for a manager's success as they dictate the ability to lead, motivate, and maintain positive relationships within the workplace.
Depending on the management tier, the skills necessary can range from a deep understanding of the technical aspects of the job to a broader grasp of industry practices and the strategic direction of the company.
