Why do some projects come out right? This book describes a successful transformation project whose scope, complexity and size (20,000 users) made it very unlikely that it would turn out well.áThis project is a fantastic example of how the implementation of a computer system (SAP) can act as a powerful lever for change and, with some very ambitious objectives, trigger the transformation of a large institution, allowing for the modernization and deployment of a new strategy for the entire Institut Catalá de la Salut (ICS) and, as a result, the establishment of a new corporate culture.áThis is an informative book, a book that offers a complete overview of the project from how it was conceived, to how it was executed, to how its future evolution has been ensured. Although the most significant factors involved in project management and change management are explained in detail, the most important and enriching components of the book are the first-person narratives of the different participants, both executives and users, which provide an insider´s view on aspects like the perception of the new system and the when and why of some decisions that in the end were key to the project´s success.
