What does it mean to "manage people"? (Score 2, Insightful)

With a division of labor, the idea of the manager is to strictly keep to "managing people", right? What does that actually mean in real practice? If the techies are the ones with all the actual skill to implement technology, what happens when techs have a technological debate? If a team is designing a complex system and there is a difference of opinion between two or more choices with subtle but far-reaching consequences, in the real world, is the manager going to be hands-off and stick with the "people side" only?

I don't know about anyone else, but that's not how I've ever seen it happen. The manager must make a decision about the design of the technology. How is he/she to decide? Based on which developer is a snappier dresser, or which one kisses ass more? :-) The business world needs to get rid of this obsolete idea of a "manager" who mechanistically manages human "resources". We need to be more honest about human interaction. What most businesses need are LEADERS. You can't lead if you're not in front. You want quality code from your employees? Then can YOU recognize the difference between bad and good code? In practice, good managers in IT are technically proficient AND have people skills. It's out of necessity, businesses really don't have a choice unless they want to keep burying their heads in the sand and sticking with merely "managing" their employees who they have no idea what those employees actually do.
