Six sigma implemented years ago. Engineers gave up their day to day system or component engineer jobs to become certified green belt, then black belt, then master black belt. Master black belts had no career path. Some left for GE or Coca Cola once they figured this out.
Remaining black belts , and master black belts, soon had multiple titles put on them like supervisor, tech spec, or others. Soon they found it required them to wear at least 3 hats.
Six sigma and other quality related fundamentals soon became low priority. Surviving thru the 2008, and subsequent downturns became priority.
So quality and six sigma withered.
Just a year ago they were reviving FTEP. Maybe this is a step back in the right direction.
This black belt left last November.
