In 1961, I authored my Bachlor Degree Thesis paper on the "Statistical Analysis of the Effects of Tires on Car Ride". That thesis was devoted to the complete understanding of everything associated with the requirement for tires on vehicles, the manufacture of tires, the quality control of tires, and setting design parameters which all manufacturers would use to insure all tires would have design strength greater than worse case stresses. Now days, this methodology is called "design for 6 sigma". Frankly, that is so sad, as the capability to Passionately Pursue, Plan, and Process to achieve Product Perfection should be the goal for all engineers and technicians everywhere. Even though we achieved 2 Cpk in the early 1960's, we always felt we fell short of what we were taught was possible from our tough drafting room and tool roon master mechanics. There were no allowable tolerances in those days, and if we did not achieve perfection, we did the job again and again until we reached perfection. So, I ask again, why are the current generation of engineers and technicians just shooting for 6-Sigma?
