This ArchiMate example models the management of architecture change. The “architecture” of the migration process from an old situation (current state enterprise architecture) to a new desired situation (target state enterprise architecture) has significant consequences on the medium and long-term growth strategy and the subsequent decision making process. Some of the issues that should be taken into account by the models designed in this example are:
(1) Developing fully-fledged organization-wide enterprise architecture is a task that may require several years.
(2) All systems and services must remain operational regardless all the presumable modifications and changes of the enterprise architecture during the change process.
(3) The change process may have to deal with immature technology standards (e.g., messaging, security, data, etc.).
(4) The change has serious consequences for the personnel, the culture, the way of working, and the organization.
