Decision Making - Review Notes

Introduction

Decision making is the actual selection from among alternatives of a course of action.

Decision making is involved in various functions of management. Hence, it is a step in planning. Planning occurs in managing organizations or in personal life whenever choices are made in order to gain a goal in the face of such limitations as time, money, and the desires of other people. The steps involved in planning are:

1. Being aware of opportunity
2. Establishing objectives
3. Premising
4. Determining alternative courses of action
5. Evaluating alternative courses
6. Selecting a course
7. Formulating derivative plans

Developing Alternatives

Planning comes into picture whenever a goal is to be attained. Choice of goal itself is a planning problem. If we assume that there is a goal to be achieved, the next step in the planning is to develop planning premises. Premises are planning assumptions, the future setting in which planning takes place. We can term them as the environment of plans in operation. Premises include forecast data of a factual nature, applicable basic policies, and existing company plans.

Developing alternative courses of action is taken as the first step in decision making. Managers have to develop alternative courses for any decision to be made. A sound adage for the manager is that, if there seems to be only one way of doing a thing, that way is probably wrong. More rationally, a planning priniciple called principle of alternatives can be specified. In every course of action, alternatives exist, nd effective planning involves a search for the alternative representing the best path to a desired goal.

The ability to develop alternatives is often as important as making a right decision among alternatives. Ingenuity, research, and perspicacity are required to make sure that the best alternatives are considered before a course of action is selected.

Principle of Limiting Factor

Chester Barnard has written, "the analysis required for decision is in effect a search for the "strategic factors."'
Stategic factors and limiting factors are synonyms but Barnard suggests that we use the term limiting factor for physical things and when personal or organizational action is the element, we should use the term strategic factor. When we want to achieve some goals of system, we examine its parts or factors. Strategic factors or limiting factors are those parts or factors which if changed would accomplish the desired purpose if other factors or parts remain unchanged. The principle of limiting factor says, if in developing alternatives, the more an individual can recognize and solve for those factors that are limiting or critical to the attainment of a desired goal, the more effectively and efficiently he can select the most favorable alternative.

Discovery of limiting factor lies at the basis of selection from alternatives and hence of planning.

Process of Evaluation

After a reasonable number of alternatives have been developed, the next step in decision making is evaluating these alternatives. In most decisions, there are certain tangible factors to be assessed in terms of dollars, man-hours, machines hours, units of output, rates of return on investment, or some other quantitative unit. There are other factors that can be hardly quantified. However, both the tangible and intangible factors must be weighed in deciding upon a course of action.

Evaluating the Decision's Importance

Size or length of commitment: If a decision commits the enterprise to heavy expenditure of funds it should be subjected to suitable attention at top management level.

Flexibility:Decisions involving inflexible courses of action need attention.

Certainty of goals and premises: Production decisions based on order backlog are more routine in comparision to made to stock decisions.

Quantifiability of variables: If variable can be quantified decision making is more routine.

Human impact: Where the human impact of a decision if great, its importance is high.
