But then they would never know enough about any one field to master it, and certainly not enough to build a car. On the other hand, specialists use their variety-processing abilities to learn one profession in depth. Of course, in order to work with others, specialists must use a little bit of their variety-processing abilities to know a little about everything else. With that caveat, by focusing on one field of study, specialists become very good at one thing. Then, when specialists cooperate with each other by forming an organization, the organization has both depth and breadth.
Organizations only perform better than individuals to the extent that they permit specialization.
Said another way, organizations exist specifically to allow people to specialize. Within some practical limits, the more that people specialize, the more depth they achieve and the better the organization can perform. Imagine an organization made of specialists, all of whom are very good at their respective professions, but each of whom acts independently without coordination. Actually, it would do worse than a collection of independent generalists. Since no one specialist sees the big picture, collectively they would be unlikely to get any products out the door.
