text: describe how knowledge as a competitive advantage can be negative or positive?   before i get into the iproceed principles of competitive strategy, here are a few things that i prefer when i help a firm define its basis of competition:  * think primarily from your perspectives, rather than your own.   * think positive competition (why should our customers do business with us? ) versus negative competition (why should our customers not do business with our competitors?).  * unless you have the scale advantage.  always think positive even you are a loser! http://www.iproceed.com/growth/competitive-strategy.htm
