This book reflects the tremendous changes in the telecommunications industry in the course of the past few decad
es - shorter innovation cycles, stiffer competition and new communication products. It analyzes the transformation of processes, applications andnet
work technologies that are now expected to take place under enormous time pressure.
The International Telecommunication Union (ITU) and the TM Forum have provided reference solutions that are broadly recognized and used throughout the value chain of the telecommunications industry, and which can be considered the de facto standard. The book describes how these reference solutions can be used in a practical context: it presents the latest insights into their development, highlights lessons learned from numerous international projects and combines them with well-founded research results in enterprise architecture management and reference modeling. The complete architectural transformation is explained, from the planning and set-up stage to the implementation. Featuring a wealth of examples and illustrations, the book offers a valuable resource for telecommunication professionals, enterprise architects and project managers alike.
