I've been through Good to Great a couple of times. Collins' outlines his methodology and how he picked the companies to find an underlying theme which he dubbed "The Hedgehog Principle." Using his matrix and analysis, he came up with those conclusions. Clearly, other analyses methods, equally as valid (or equally arbitrary) would arrive at different conclusions.
One of the obvious problems with the Hedgehog Principle is when people stop using whatever your company does best. Then you are left with an excellent, albeit unsellable product or service. and in order to survive you need to find a new hedgehog.
