Decision making involves a multi-step process of identifying a decision to be made, gathering relevant information from various sources, assessing alternative resolutions, weighing the pros and cons of each option, selecting the best alternative, taking action, and reviewing the outcome. The steps include defining the nature of the decision, collecting internal and external information on the topic, identifying possible courses of action, evaluating each alternative in terms of meeting the initial need, prioritizing the options, choosing one to implement, taking positive action, and considering the results of the decision.
