Every company has a strategy. Whether it ‘does strategy’ explicitly or not, the choices that it makes on a daily basis result in the company operating on some part of the playing field (i.e. making a where-to-play choice) and competing there in some fashion (i.e. making a how-to-win choice). It matters not a whit whether the industry is highly uncertain, every company competing in it has a strategy.
Without making an effort to ‘do strategy,’ though, a company runs the risk of its numerous daily choices having no coherence to them, of being contradictory across divisions and levels, and of amounting to very little of meaning. It doesn’t have to be so. But it continues to be so because these leaders don’t believe there is a better way.
