Background

In November 1997, while observing my annual leave from work(as a 27 year old brewer in Guinness Benin Brewery), I wrote and presented a paper titled "Statistical Process Control (SPC) and Target Setting" at the 1997 edition of the Nigerian Institute of Management's Young Manager's Competition. The paper was based on work I had done(mostly in my free time) in setting up various process control/reports computerisation systems in departments(Production/Brewing and Packaging/Bottling) where I worked.

The paper discussed the use of CUSUM(Cumulative Sum Deviation) charts, Total Waste Unaccounted For(TWUF)
