CEVAP:

The decision-making process starts with identifying a problem or opportunity. In order to initiate the decision-making process, one should feel the need to decide. The need to decide can be external or internal. If a problem or opportunity is brought to the attention of the relevant person or people by outside parties, then the trigger for decision making is external. If the decision maker takes initiative and chooses to come to a decision, then there is an internal trigger for taking a decision. Sometimes people can be driven to decide both internally and externally.
