No sorry all those companies don't practice Welch's stack ranking methods.
As per the Welch system, if each manager cuts down 10% of his under performing team. The managers themselves get stack ranked in their managers staff all the way up to the CEO. There fore managers themselves get ranked and cut. But that is not what we see most companies. In many of those companies the axe falls only on people working on grass root levels. And the managerial layers get thicker and thicker and years pass by.
Also for this you need a very good leader at the very top who can drive this. Jack Welch could do it because its his system. Other just do it because they have to.
I worked for G# before and it did not happen that way. Managers did not get stack ranked. Every manager had a mandate to push 10% or 5% of their team as bottom 10 or 5. And, I should add that this was may be because, it was in the IT side and they did not have the luxury of letting go of people. So the bottom 5/ 10% was not moved out. They were handed a rating and the performance improvement plan that goes along with that.
