"Strategy is a very broadly used term applied in military, political to business situations. Lawrence Freedman illustrates in his book "Strategy - A History" the origin of strategy though mythical figures, politicians and business leaders. They all have in common to take decision under uncertainty and confusion of the human affair. Strategic decision making aims to clarify in these moments of uncertainty with an applied set of problem-solving principles. It is therefore a problem-solving methodology that is applied to complex, unstructured and multi-dimensional issues, driven by the uncertainty of human behaviour and decision making. Max McKeown specifies in "The Strategy Book" that strategy is about shaping the future by which people attain desirable ends with available means. Authors such as Igor Ansoff, Henry Mintzberg and Michael Porter established during the last 50-60 years a corporate discipline that aims to combine a rigorous planning approach with adaptability to the circumstances given the uncertainty of the situation"-- Provided by publisher.
