After the model is solved, validation of the obtained results must be done in order to avoid an unrealistic solution. This stage of decision making process is the most important aspect of the decision making process. The decision maker may be unfamiliar with analytic details of the problem formulation such as what elements to include in the model, and how to include them as variable, constraints, indexes, etc. Since the strategic solution to any problem involves making certain assumptions, it is necessary to determine the extent to which the strategic solution changes when the assumptions change. Gathering reliable information at the right time is a component of good decisions.
Uncontrollable factors are the main components of decision-making.
Evaluate the various courses of actions within the controllable inputs, considering various scenarios for uncontrollable inputs, and then decide the best course of action. As you know, the whole process of managerial decision-making is synonymous with the practice of management. Decision-making is at the core of all managerial functions. Other managerial functions, such as organizing, implementing, and controlling, rely heavily on decision-making. Preparation for management, whether it is related to technology, business, production, or services, requires knowledge of tools, which can aid in the determination of feasible, optimal policies.
