Summary:

The basis for an Enterprise Architecture IT project comes from the identification of the changes necessary to implement the enterprise or organisations strategy, and the growing information needs arising from this, which increases the demand for the development of the IT system.

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.
