When starting a business, entrepreneurs take a substantial amount of risk and uncertainty. In recent times, how we can find a clue to deal with a world that is a complex which is still unanswered. Thus dealing with uncertainty and complexity are becoming increasingly important. Risk refers to situations in which the outcome of an event is unknown but the decision maker knows the range of possible outcomes and the probabilities of each such that anyone with the same information and beliefs would make the same prediction. Uncertainty, by contrast, characterizes situations in which the range of possible outcomes is unknown. Strategic management theory helps provide knowledge into the empire of uncertainty i.e. strategic planning. One of the key to make the future manageable despite its complexity might be due to future developments based on past and present experiences.
