All decision makers rely on information as the basis for making informed business decisions.
However, different types of decisions require different types and amounts of information. In some situations, decision makers may feel that they already know or have access to all the information they need to take appropriate action. In other cases, a decision is made only after an extensive data collection and analysis process. The type and amount of information required may also be a function of the perceived importance of the decision being made. Sometimes, decisions are made by default, or a decision is made not to decide or to defer a decision until more information is available.
