Final answer:
Top managers in modern business environments are primarily responsible for setting strategic goals and ensuring cross-departmental cohesion, rather than daily supervision of nonmanagerial employees.
Step-by-step explanation:
The subject at hand concerns the roles and responsibilities of top managers in modern business organizations. Addressing the options provided, option E is correct, stating that top managers have cross-departmental responsibility. This is because top managers hold high-ranking positions within an organization and are typically involved in shaping the company's strategy, establishing organizational goals, and ensuring that different departments cohesively work towards these goals. They do not usually deal with day-to-day supervision of nonmanagerial staff, which is generally the responsibility of lower-level managers or supervisors. Instead, top managers are more focused on the bigger picture, which includes leading, controlling, planning, and organizing various functions of the business. These tasks are crucial for maintaining the health and profitability of the organization as a whole.
