I think it's largely a function of the intrinsic reason that someone wants to lead. Are they in it for the title or the prestige? Their desire will as some point run in conflict with the larger program goals. Do they do it because they enjoy bringing a diverse set of viewpoints together to create something that couldn't be created in isolation? That might have a better chance of success. Unfortunately it's very difficult to determine this externally without a significant investment in time or otherwise.
