Everyone claims they have a strategy.
One of the best ways for testing any person's or company's strategy is the organization's ability to say 'no' to opportunities.
Strategy should inherently focus an organization's resources and investments. And by definition, a strategy then limits what can be invested in.
So next time you are considering a strategy, ask yourself and your partners, what does this eliminate? If if doesn't eliminate much, then its pretty useless.
The arithmetic here is where there aren't easy and enforceable "no's", there won't be great "yes's" and will limit returns for the strategy.
