Frameworks
The Landmark Blue architecture frameworks are used as a starting point for planning architecture activities. The frameworks scale well both up and down, hence can be the basis for change processes for both larger and smaller organizations.
Enterprise Architecture Perspectives
Enterprise Architecture (EA) is about the organizational and technological entities in an enterprise, and the relations between them. As an activity, the goal of EA is to improve how all these entities support the business and IT goals in a better way, not just solution by solution, project by project, but for the business as a whole.
Enterprise Architecture Phases
EA is mainly about defining a target architecture, and planning how to establish it. In order to get there, there are a number of phases you need to go through. You also need to execute these iteratively, because you need to adapt to internal or external changes, and you want your models to always give a realistic view of the organization’s processes, information, services, applications and technology.
