Decision Process

The ultimate goal of a decision process is to solve a decision problem, that is, to make a decision. In Decision Analysis, the decision process is understood as a process of careful and in-depth analysis of the decision problem. It involves a systematic acquisition and organization of knowledge about the decision problem, which is done by participants of the decision process and typically includes:

  • assessing the problem,

  • collecting and verifying information,

  • identifying options (alternatives),

  • anticipating consequences of decisions,

  • making the choice using sound and logical judgment based on available information,

  • justification and informing others of the decision and its rationale,

  • evaluating decisions and their consequences.

In general, such a process should:

  • provide all the information needed for a ‘sufficiently good’ decision,

  • reduce the chance of overlooking important information and making other errors,

  • improve the effectiveness and efficiency of the decision-making, and

  • improve the quality of the decision itself.

Usually, the decision process involves at least the following steps:

  1. Problem identification

  2. Modeling: developing a decision model

  3. Evaluation and analysis of options

  4. Choice: making the decision

  5. Implementation of the decision
