Apparently, his dad was a management consultant engaged by the BSA Group and came up with some interesting conclusions before being dis-engaged most likely due to the home truths being too hard to stomach.
One finding of particular interest was the fact that no-one knew how much it cost to make a motorcycle as no-one recorded costed bills of materials and labour.
It seems this was endemic as I remember reading somewhere that Michael Edwardes had the same problem when he took over at British Leyland in the 1970's and was horrified to find out no-one could tell him how much it cost them to produce a Morris Marina!
Back a BSA, it also seems production planning was so poor, parts were made when convenient to the machine availability, not when it was required for assembly. It all sounds so familiar as to how our industries were run in those heady days. Thanks to the influences of the Japanese on the Americans and then on us, we do things alot better now. It took us until the mid eighties to catch up though!
