Following up the post yesterday commenting on the changes the net has wrought in relation to Michael Porters ideas about substitutes. It seemed useful to add links to two useful articles by Joan Magretta, who has written a book on Porters work.

The first is the strategy mistakes Porters sees most commonly,  and the second a great list of strategy  do’s & don’ts.

There are many lists on the web, bloggers particularly know that response rates go up substantially with a list in the headline, but if you are going to take notice of anyone, it may as well be one of the giants of strategic thinking.
