The development of an IT system can be carried out using an urbanisation approach i.e. building an IT system using the metaphor of a city. This concept is based on the fact that in constructing or reorganising information systems, the reconstruction and modernisation involves permanent elements, as are found in a city. Although relatively new, this approach has been successfully employed in a number of projects over the past few years.
The practical approach given in this book allows enterprises or organisations trying to safeguard the efficiency of their IT system, while minimising costs and risk, to implement the theory and put it into practice.
2. Illustration of the approach: i. the tour operator case study. ii. Urbanism and strategy: harnessing and modelling the strategy; objectives model; enterprise diagram; case study. iii. urbanism and business processes: business processes cartography; process modelling; evaluation and improvement of processes; case study. iv. Urbanism and functional architecture: functional and business architecture; the urbanism rules; case study. v. urbanism and software architecture: software and functional architecture; software cartography; transition from target functional architecture to target software architecture; case study.
3. The methodological approach: defining the target and the associated migration plan; construction of the solution; urbanisation process of IT system.
4. The dynamic of the actors: the participants and their roles; skills, techniques and tools; new approach to relationship between project ownership and management; the urbanism focus group.

He is also in charge of the Enterprise Architecture programme at the IMI (Information Management Institute, University of Technology at Compiegne, France). His work now focuses on Enterprise Architecture design, where his activity objectives are to allow enterprises and major administration to focus their investments on the major stakes and thus preserve their previous investments while minimising risk with a controlled and gradual overhaul of existing systems.
