A decision maker is a person who has the power and through this power seeks to make decisions that address the problems facing his organization.
Knowledge is one of the most important elements he needs to make such decisions. The world of decision-making is a world full of difficulties, ambiguities, and uncertainties. In order for the decision maker to take appropriate decisions that have a positive impact, he needs knowledge that enables him to dispel ambiguity, reduce difficulties and risks, and take the right decision. This means that there is a consistent “demand” for this type of knowledge, and consulting firms are one form of supply they seek to respond to. That is, they are companies that sell this kind of knowledge to decision makers to get them to make the right decisions.
