Quotes by Michael Porter

Change brings opportunities. On the other hand, change can be confusing.

Finally, strategy must have continuity. It can't be constantly reinvented.

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.

Strategy 101 is about choices: You can't be all things to all people.

The ability to change constantly and effectively is made easier by high-level continuity.

The essence of strategy is choosing what not to do.

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.

The underlying principles of strategy are enduring, regardless of technology or the pace of change.
