I would wager, though, that most folks like more variety, particularly the ones who are expected to create stuff, and I'm not strictly talking computer programming. Why, then, do we see management apply the Henry Ford assembly line specialization model to places that are supposed to produce innovative designs, techniques, content, solutions, what-have-you? If you have knowledge workers reporting to you, what brain-fever would prompt you to create an official R&D department?
Because when you make it official, you're doing two flavors of damage to the organization:
- You're basically off a playground area and letting only a few kids in it, with no recess for the others. That's sheer poison by itself, let alone the damage even a single remark from the "privileged" kids to those slaving away in the coal mines and mills next door can wreak.
- You're also teaching those in the playground that it's someone else's responsibility to sell the ideas to the rest of the organization, and to see them through actual implementation.
Yes, it costs something (if only in terms of vigilance and, maybe, political capital) to gamble on an untried person or group. But I can pretty much guarantee you that doing anything else is most certainly not a gamble--it's a sure-fire loss in the long run.
