As a participant in a cross-cultural awareness course we used this book as a guide. It has become a very helpful guide to get an idea about why people do things differently across the world. Ever wondered why Germans tend to plan or US guys want to do the surface dive on matters, ready to jump from one occasion to the next? This book will give you the clue. Please note - you will still not be able to understand the British people though... Trompenaars & Hamden-Turner have put loads of experience and fieldwork into this book, you feel this in each and every single line. The information provided is thorough but does not tend to go overly into too much detail, which is good - otherwise you might feel encouraged to think you are in a social science class. The book guides the reader along seven areas which cover most of our cultural differences. Factors like time, individualism or the "shallowness" of relationship is covered. This book has been a valuable support in my daily work. I learn to put the ideas and values from the book into daily practice, e.g. when dealing with People from Mexico who never meet a deadline. Now I finally understand, why they don't. From my point of view, if you do business or other non-business relationship with people from other countries, read this book and grasp, why "they" behave as they do.
