Representation of the organisation
An enterprise architecture represents the organisation and captures its structure, structural dependencies and measures of value. Many different frameworks have been developed over the years that tackle different aspects of an enterprise's structural entities, functions and resources. Often these frameworks focus on just one of the Capability, Delivery or Operational stakeholder concerns. An enterprise architecture needs to support all stakeholder concerns in order to become part of an organisation's culture.
Business Services & Information
ICT Services & Data
Assets / Technology & Consumables
Implementation and migration
Data associated with the enterprise architecture needs to be stored to allow ease of access across teams working at different levels of detail and on different parts of the architecture.
Architecture Repository
The transition to new IT systems and services requires careful assessment and planning. The architecture deliverables and processes should support and enhance the decision-making capability at the portfolio, programme and project levels.
