In selling, we face two types of competition: internal (peer competition) and external (market competition). In both cases, we learn and practice competition as a war where one must lose for the other to win. In other words, a zero-sum game.
I always try to avoid zero-sum games and transform them into positive-sum games, meaning that both competing parties can be better off in the end. But how can this be possible when selling in a competitive environement?
