Not to defend stack ranking, but those analogies don't support your point. Most Americans would be better off losing the worst-performing 10% of their body. I probably lose close to 10% of my friends in any given year as we drift apart. Knocking down part of your house is a good thing if you're remodeling, and not comparable otherwise, assuming the company is hiring at at least replacement rate.

There is some logic behind always hiring the best you can find and having a process to cull the low performers. It's not like the company's actually shrinking by 10% every year. The problem only shows up when you hit a point of actually having all high-performers, and you're only throwing people away to meet a quota that's become counterproductive.

No, no, the problem is that skill distribution is not random in an organization. Let me give you a very real example: I am contracting for a big company that has its own form of stack ranking. I've spent this last month with a team where the very best member they have seems to be in the bottom 10%. In comparison, I've worked with other teams where their worst performer is very competent, and would be a developer king in the first, low performing team. But with their stack ranking, the worst player of a good team is ranked lower than people from the bottom 10% team.

Even if hires were assigned teams at random, attrition doesn't occur evenly. Bad teams lose good people very fast. Teams with bad managers will have huge rates of churn (people rarely quit their job, they quit their manager). So the end result is to naturally divide into multimodal distributions: Rich get richer, poor get poorer. Since ranking teams is, from an organizational perspective, extremely political, you'll rarely get management to point fingers to the bad teams.

Also, splitting a high performing team rarely works: A team is not a collection of individuals, but also a culture. Dump a great performer on a bad culture, and even if you put him in charge, you do not get a good culture: Instead, you get less out of that person.

If there's anything I've learned, is that we are better off ranking teams, not people. The one reason to look inside a team is for voting people off the island, and that is something that should be started from within a team.

Your second paragraph exactly matches the point your parent wanted to put across. Yet, you typed in the first paragraph. You want to show you got more insight, huh?
