I am involved in post graduate management courses via our deanery, and one lecture I give each year for the MBA module in transferable skills , (the third one is next week by coincidence) is the HISTORY of six sigma approach.

I reckon that, with glasses pushed up to to bridge of nose accordingly, that makes me a historian every bit as much as a hack writing history. Real historians would weep at the thought of either Hastings or me, but as it isn't a protected title, a hell of a lot of people spout shit on a self titled or lazy association basis.

Do you wish to enrol for Module 101 Revisionist skills? Past experience taken into account, you already have half the points so won't need to do the foundation course. You won't need to trawl the internet for articles to cut and paste either. (Here's a thought. Read them first. Dr Sheffield makes a case in one of them that runs fully contrary to your general thrust.)
