I fully disagree with Dave here; a degree is not a finite measurement of one's ability -- there are plenty of people without degrees with high intelligence that have taken the initiative to learn on their own, and there are plenty of people with degrees that are unable to digest the knowledge/apply it to real world situations -- but in general, people with solid education backgrounds typically make better, more informed decisions than those without.
For example... our Preload has eight irregular trains but has been struggling to get irregs down "on time." An educated manager would search for the constraint --is it a capacity issue? Probably not since each train spends vast amounts of idle time. So it's probably a bottleneck... perhaps the fact that a large number of pieces need to be d-capped, and that's a time consuming process (previously they were dropped off at a clerk station, but management frowns upon it)... additionally, the line-up changed and one belt's cars block the trains, thus requiring the pieces to be manually carted, again a time consuming process. So what does the Preload manager do? She orders two more irreg trains!!! Capacity is not the issue so it's going to worsen the problem. But I'll bring some popcorn in and enjoy the show

As management theories advance, there's a reason why companies like CVS, etc. -- which use to promote from within -- will only consider college grads for managerial positions. UPS isn't there yet but probably one day will be.
