A good idea, badly executed with sloopy thinking.

Some of the examples are nearly ramblings, some of the formulas are so wrong I wonder if anyone proof-read the book. And some are so basic, an nine-year old could do better.

In short, it looks fancy at the surface, but the contents are for the most part plain stupid. Some budding manager may be able to get some value out of this, but it is a waste of space for any MBA or experienced manager.
