I disagree that glue is expensive and complex. When you build a ply-wood tower in school to see who's holds up the most to compression, you don't douse your entire structure in glue. You get points off, because it adds so much to weight!
People are the plywood, fragile, finicky, and useless if left to their own devices. Management is the middle school kid who needs to take the wood he's been given and make something that will hold up to all the weight that'll be put on top it. In order to do this, he's been given a hot glue gun and enough glue to mummify the entire thing if he so chooses. Most of the kids will rush bullheadedly (or should I say uncaringly) into gluing the sticks together into something that "looks like it should work." They use too much glue, the structure isn't optimized for load handling, and when the day of truth comes, it crumbles down when the bucket that's supposed to hold the weight, destroys it!
What is glue? Whatever management wants it to be. It can be a team leader or a hastily configured IRC channel. In my experience (this includes organizing, delegating, and making sure that 40 devs-et-al get what's needed done), if you choose your sticks right, taking the time to make sure they're not hiding any structural faults, you can make the job 65% easier. If you lament that choosing sticks if difficult, I reply with "it's just practice."
The main issue I've seen, has been the all too common "there are no good managers." Especially in technology. The remedies for this? There's no bandaid. Each manager has to realize his personal shortcomings and fix them. But, to throw up his hands and say "the more people working on a project, the slower it'll get done," is a nice way to say "I can't handle all these people, but I'll excuse that away by saying it's inevitable. It's even industry 'common sense!'"
In human organizations, that glue itself gets incredibly complex and expensive, as number of pieces grow.
