Most companies have lots of people with different skills. The problem is, when you bring people together to work on the same problem, if all they have are those individual skills—if they are I-shaped—it’s very hard for them to collaborate. What tends to happen is that each individual discipline represents its own point of view. It basically becomes a negotiation at the table as to whose point of view wins, and that’s when you get gray compromises where the best you can achieve is the lowest common denominator between all points of view. The results are never spectacular but at best average.
