During my Msc. of Management eduction, now 12 years ago, I used an older version of this book. This one is better because it provides a more concise overview of the material and highlights in a much more better way the important topics of strategy. It is not only a theoretical book but a lot of illustrations make the material to be become more understandable.
I bought it for this reason and I must say, I am very happy with it. It now comes together with a free internet acces for 12 months for further exercises and explanations. You will not regret if you buy it.
