Unit 2: Decision Support
Self Assessment Notes
Fill in the blanks:
7. The ........................... Model is prescriptive in that it focuses on how decisions ought to be
made.
8. In case of ........................... Model, Decision making proceeds sequentially.
9. In ........................... Model, “decision making” is essentially a process of confirming a choice
/decision that has already been made.
10. In ........................... model, potential problems and conflict often can be foreseen and
minimized.
2.4 Phases of Decision Making
There are four major phases:
1. Intelligence: Decision maker examines reality and identifies the problem; problem
ownership is established as well.
2. Design: The model (that represents the system) is constructed making assumptions that
simplify reality and writing down the relationships (among variables). The model is
validated and criteria are determined (choice of evaluation); identifies alternative solutions.
3. Choice: It includes selection of a proposed solution (is tested for viability) to the model.
If solution is reasonable we may pass to the next phase else we must return to an earlier
phase.
4. Implementation: It provides the successful result in solving the real problem.

These phases are discussed below:
2.4.1 Intelligence Phase
The intelligence phase involves scanning the environment – identifying problem situations
(opportunities), monitoring the results of implementation.
