On Marvel's Agents of S.H.I.E.L.D., one of the characters said that she was part of an organisation because one person might not have the whole answer, but 100 people with 1% of the solution will get it done. Those 100 people would still need a coordinator to fit them together, though. A 100-piece puzzle doesn't assemble itself.
