The topic of product management is of central importance for the success and long-term survival of all companies, as well as for achieving and maintaining a certain market position. General books on product management often do not meet the specific requirements and processes in the software industry. This book, written by experienced practitioners and executives from diverse backgrounds (hardware and software manufacturers, service providers, IT consulting, users), describes the topic of software product management from various perspectives. The focus is not limited to the pure product management of standard software but also takes into account that most "products" in this environment consist of a complex combination and interconnection of standard and custom software with services.
