Complementarity

Complementarity: an economic term describing when you put together skills / goods from different sources, they complement each other and produce good that is better than on its own. People who building a company are not typically great at running then because these are two totally different set of skills - entrepreneurship & management, which require both the founders and the ceo. Physicists and journalist also complement in theory; physicist does the research, and the journalist publish and sells it. -Steven Dubner
