In the context of incremental decision model, describe the selection phase of decision making

The selection phase of decision making is when the solution is chosen. This phase is not always a matter of making a clear choice among alternatives. In the case of custom-made solutions, selection is more an evaluation of the single alternative that seems feasible. Evaluation and choice may be accomplished in three ways. The judgment form of selection is used when a final choice falls upon a single decision maker, and the choice involves judgment based upon experience. In analysis, alternatives are evaluated on a more systematic basis, such as with management science techniques. Mintzberg found that most decisions did not involve systematic analysis and evaluation of alternatives. Bargaining occurs when selection involves a group of decision makers. Each decision maker may have a different stake in the outcome, so conflict emerges. Discussion and bargaining occur until a coalition is formed, as in the Carnegie model described earlier. When a decision is formally accepted by the organization, authorization takes place. The decision may be passed up the hierarchy to the responsible hierarchical level. Authorization is often routine because the expertise and knowledge rest with the lower-level decision makers who identified the problem and developed the solution. A few decisions may be rejected because of implications not anticipated by lower-level managers.
