Techniques Used in Different Steps of Decision Making

In the models of decision making, you must have observed that any systematic approach to decision making starts with a proper definition of the problem. You will often experience that a problem well defined is a problem half-solved  because the proper definition helped you to search at relevant place for promising alternatives. You would also agree that a "fair" approach to decision-making demands that parameters (for judging alternatives which are sometimes referred to as "criteria", "level of aspiration", "decision rules", etc.) should be explicitly developed before the alternatives are generated and not after. This imperative minimizes the chances of unnecessary compromise which is the hall-mark of a low-quality decision. However, once you have developed the criteria, keep them aside and forget about them at the time of generation of the alternatives. This dissociation of criteria from the alternative-generation phase will improve your chance of coming up with a reasonably sufficient number of alternatives. You will understand the importance of generating a "reasonable" number of alternatives by the simple realisation that the quality of a decision can be no better than the quality of the alternatives that you identify.
