Whilst out with friends at dinner the other day the conversation turned to diets. Turned out that at our table of eight people five of them were on one sort of diet or another. As I listened to the conversation it became apparent that most had been on other diets before with varying degrees of initial success but after a while the initial weight was regained, sometimes with an extra kilo or two.

Now I don’t profess to have an expertise in this field although I have always wondered why, if any particular diet works, there are so many others?

If you truly do get what you measure it is interesting to note that many traditional organisations rely on metrics that are focused on operational features like cost of labour, raw materials and production output vs. sales projection or forecasts. Making decisions in the current business climate on such narrowly defined operation factors, see examples in Table 1, could prove disastrous.
