Somasegar has an excellent post on Strategic Thinking. He defines strategy as being composed of the following three processes:
Thoughtfully define your destination
Realistically identify your current position
Anticipate tectonic shifts and plan for them

The mistake people make in identifying their Point B is to think about the success of their immediate products. Â One needs to go deeper and understand the fundamental reason why their products exist.
(Point B being the destination they are trying to define). Read the full post here: Strategic Thinking
