Here is a book that aggregates five years of experience of three successive R and D projects (ELCH, GetTogether, GROPIS) covering technical and organizational issues of eProcurement. The projects, which were funded partly by the government and partly by industry and hospitals, looked at the characteristics of procurement processes and at standard technologies. Two of the projects included case studies (ELCH, GROPIS), the third project focused on the development of standard business objects for eProcurement in healthcare (GetTogether). Together they form a rich source of information worth communicating to a large audience of experts and newcomers alike. Results from the projects are supplemented by the contributions of international experts and their views on eProcurement, which give the book a global perspective and hence allow its readers to learn from a variety of different approaches. Each chapter of the book is structured in a way that satisfies the needs of executives as well as academics.
