This is a book accompanying "Good to Great", which I haven't read, applying it to non-profit organisations. At £6.99 its quite expensive for a slim volume, but it has some wise words.
As the title applies it takes the principles of the main book and tweaks them. The "pivot point" of the main book is the Hedgehog Concept, the essence of which "is to attain piercing clarity about how to produce the best long-term results, and then exercise relentless discpline to say, "no thank you" to opportunities that fail the hedgehog test". So its an antidote to violent swings of direction in the organisation.
There's a good quote about what makes non-profits different:
"In business, money is both an input (a resource for achieving greatness) and an output (a measure of greatness). In the social sectors, money is only an input, and not a measure of greatness."
It's a handy book for when strategic thinking is needed, or needs evaluating, and I'd recommend it.
