Decision making is the cognitive process leading to the selection of a course of action among alternatives. Every decision making process produces a final choice. It can be an action or an opinion. It begins when we need to do something but we do not know what. Therefore, decision-making is a reasoning process which can be rational or irrational, and can be based on explicit assumptions or tacit assumptions.
Common examples include
shopping, deciding what to eat, when to sleep, and deciding whom or what to vote for in an election or referendum.
Decision making is said to be a psychological construct. This means that although we can never "see" a decision, we can infer from observable behaviour that a decision has been made. Therefore, we conclude that a psychological event that we call "decision making" has occurred. It is a construction that imputes commitment to action. That is, based on observable actions, we assume that people have made a commitment to affect the action.
Structured rational decision making is an important part of all science-based professions, where specialists apply their
knowledge in a given area to making informed decisions. For example, medical decision making often involves making a diagnosis and selecting an appropriate treatment. Some research using naturalistic methods shows, however, that in situations with higher time pressure, higher stakes, or increased ambiguities, experts use intuitive decision making rather than structured approaches, following a recognition primed decision approach to fit a set of indicators into the expert's experience and immediately arrive at a satisfactory course of action without weighing alternatives.
Due to the large number of considerations involved in many decisions, computer-based
decision support systems have been developed to assist decision makers in considering the implications of various courses of thinking. They can help reduce the risk of human errors. The systems which try to realize some human/cognitive decision making functions are called Intelligent Decision Support Systems (IDSS), see for ex. "An Approach to the Intelligent Decision Advisor (IDA) for Emergency Managers, 1999".

kalau plan dulu most probably decision tu akan jadi lagi bernas kot.. contoh macam programming.. kalau buat psudocode dulu.. less trial and error..
