Final answer:
Middle management is most responsible for direct, short-term results and takes the lead in tactical planning.
Step-by-step explanation:
The tier of management most responsible for direct, short-term results and taking the lead in tactical planning is the middle management. Middle managers are responsible for translating the strategic objectives set by top management into actionable plans and goals. They closely supervise operational activities, monitor performance, and make decisions to achieve short-term targets.
For example, a middle manager in a fast-food restaurant would be responsible for ensuring efficient operations, managing staff, and meeting daily sales targets. They would use their tactical planning skills to schedule shifts, coordinate orders, and ensure customer satisfaction.
Overall, middle managers play a crucial role in implementing the organization's strategy and achieving immediate results.
