The purpose of this article is to describe a step-by-step process for decision making, and a model is developed to aid health care managers in making more quality decisions, which ultimately determines the success of organizations. The DECIDE model is the acronym of 6 particular activities needed in the decision-making process: (1) D = define the problem, (2) E = establish the criteria, (3) C = consider all the alternatives, (4) I = identify the best alternative, (5) D = develop and implement a plan of action, and (6) E = evaluate and monitor the solution and feedback when necessary.
