Hedgehog concept

In Chapter 1 we discussed Collins s book Good to Great. We described the hedgehog concept, which was one of the two fnndamental steps in transformation to a great company. Part of this concept was the determination of what the company needed to measure. For example, it was critical to Walgreens to measure profit per customer visit, rather than profit per store or profit per territory. This was not a simple or trivial decision. Collins reported that companies took an average of three years to develop a successful hedgehog concept.
