Ah, the gentle art of mechanics. It should be a qualification for certification for every mechanical engineer to disassemble an engine down to each bolt and piston ring and rebuild it to hum (I've done a few) as it should be for every computer engineer to rebuild a wonky motherboard (and debug a peripheral driver) and every physician to be a hospital patient (been there too). One can't be a real engineer or physician without experiencing the practice of one's profession. Unfortunately, management MBA's are only trained by case studies of the latest corporate wheeze (most of which went bankrupt five years later) and can only relate to the sizzle and not the steak (viz. the latest verbiage from Boeing
PR).
