According To Mintzberg (2000, p. 17), strategy requires a series of definitions and that is "one of those words that inevitably we define in a way, but often we use another. Strategy is a pattern, namely, consistency in behavior over time ".
The series of five definitions (the five Ps: Plan, Pattern, Position, Perspective, Ploy) of Mintzberg (2000): Strategy as plan (first P, Plan), namely, the intended, is the strategy defined according to a plan for the future. Deliberate strategies are the intentions that have been perfectly carried out and the unrealized strategies irrealizadas. Have, still, emerging strategies, namely, the adaptation to unexpected events, that happens when the standard is not intended and held that with the time converged to some kind of standard or consistency. The convergence of deliberate strategies and emerging strategies is the default Strategy (According to P, Pattern), namely, the effectively held.
The strategy as position (third P, Position) is the location of certain products in certain markets and that, According to Michael Porter, (apud MINTZBERG, 2000, p. 19) "strategy is the creation of a unique and valuable position, involving a different set of activities ".
The strategy as perspective (room P, Perspective) is the fundamental way for an organization to do things, According to Peter Drucker (apud MINTZBERG, 2000, p. 19) This is the "theory of the business".
Finally, and the "fifth P", Ploy, is the strategy as trick, namely, a specific maneuver to trick an opponent or competitor.
It, to synthesize, Mintzberg (2000, p. 274) ends his book "Strategy Safari", in which presents the ten schools of strategic management, with a paragraph that conveys the complexity of forming a strategy, which is:
"It won't be easy. The formation of strategy is a complex space. And ten is a very large number for brains used to seven plus or minus two. But the error, dear Brutus, It's not even in the stars or in us, but in the process itself. The formation of strategy is an arbitrary design, intuitive insight and intuitive learning; It involves processing and also perpetuate; should involve individual cognition and social interaction, cooperation and conflict; She must include before and after programming analysis, as well as trading for; and all this needs to be in response to the one who can be a demanding environment. Just try to put all that aside and see what happens!”
