Is strategy dead?

Is strategy dead? The curriculum currently taught at business schools revolves around an internal and external analysis seeking to identify a sustainable competitive advantage - so far so good. 

Whilst many of the strategy textbooks are similar in nature, the underlying principles of strategy formulation revolve around vision, mission and values leading to external and internal assessments leading to Porter's five generic strategies, strategy analysis, implementation and evaluation. 

It may be argued traditional strategy is dead, it may also be argued that strategy evolved from military origins of setting objectives, collecting intelligence and making decisions based on the achievement of the stated objectives. 

Adaptive strategy revolves around a rapidly changing business environment requiring a less static approach to business based on fluid interpretation and rapid implementation. The downside is that this may be too reactive relying more on seat of the pants type business management that generally leads to failure. So no, strategy is definitely not dead.
