Quotes by Michael Porter
The essence of strategy is choosing what not to do.
Strategy 101 is about choices: You can't be all things to all people.
The underlying principles of strategy are enduring, regardless of technology or the pace of change.
The thing is, continuity of strategic direction and continuous improvement in how you do things are absolutely consistent with each other. In fact, they're mutually reinforcing.
So companies have to be very schizophrenic. On one hand, they have to maintain continuity of strategy. But they also have to be good at continuously improving.
Change brings opportunities. On the other hand, change can be confusing.
Finally, strategy must have continuity. It can't be constantly reinvented.
The ability to change constantly and effectively is made easier by high-level continuity.
