This chapter discusses the foundations of planning and decision making. It defines planning as involving setting goals for an organization and establishing strategies to achieve those goals. Managers plan to provide direction, reduce uncertainty, and improve performance. There are different types of goals including mission, strategic, and operational goals. Plans can be strategic, tactical, or operational based on their breadth and long-range, intermediate, or short-range based on their time frame. Management by objectives is an approach where goals are jointly set by managers and employees. Rational decision making follows steps of defining problems, identifying alternatives, evaluating them, selecting an option, implementation, and review. However, bounded rationality and intuition also influence decisions.
