TOGAF 9 and ITIL V3
This paper describes the development of TOGAF (The Open Group Architecture Framework) and ITIL as a background to discussions about the potential overlap in the processes they both describe. It does not describe the models themselves. The development of information systems in large organizations, and in multipart supply-and-demand chains, has become complex and flexible. The way in which systems are being designed and managed depends increasingly on a structured approach. Best practice models are based on the experience of day-to-day users and therefore they support their needs. Their development follows the requirements of the organizations that use these models. In a way they change from descriptions of best practice to theoretical models on how processes should work in practice.
