Our project and service methodology has been developed over more than 10 years as the essence of a variety of IT service management approaches. On the strength of networked best-practise processes of the IT Infrastructure Library (ITIL), our primary project goal is to provide the core requirement in a functional prototype. Based on the experience gathered and the feedback from customers, all the other functionalities are provided in phases. Within these phases, cycles of tests, reviews and valuations are conducted until the full desired functionality is available as a productive entity. The advantage of this methodology lies in the combination of experience of ITIL processes, flexible implementation and adjustment mechanisms for agile methods and controlling the procedural steps and results in a business dministration context.
