This revised edition is the first text book In English specially developed for training for IPMA-D and IPMA-C exams. In this 3rd edition, the text has been restructured to better align the content with the order of the competence elements in the ICB version 3, divided into Technical competences, Behavioral competences and Contextual competences. For this reason it has been improved as a study book for everyone studying for the IPMA-D and IPMA-C exams. Besides that it is a extremely rich source book for those project managers that have committed themselves to a lifelong professional development. In addition, the book had to be applicable to groups of project managers originating from diverse cultures. For this reason, this is not a book that tells how a Westerner must behave in an Arab or an Asian country, but one that looks at the different subjects covered in the ICB, as seen from diverse cultural standpoints. Each chapter is based on the same structure: Definitions, Introduction, Process Steps, Process steps, Special topics. Text boxes, additional to the main text, give additional explanation to the main text. An elaborate Index of terms allows that this book can be used as the information source to all aspects of project management.
