Enterprise and business architecture

Aligning an organisation's technology strategy with its business mission, strategy, and processes and documenting this using architectural models.

Enterprise architecture is typically considered across four domains: business, data, applications and infrastructure technologies. It may also include information security or legal and regulatory compliance.
Activities may include — but are not limited to:

- translating business strategies and objectives into an operating model
- assessing current capabilities and identifying required changes in capabilities to achieve objectives
- describing the interrelationships between people, organisation, service, process, data, information, technology and the external environment
- creating, iterating, and maintaining architectural models and views embodying the key principles that describe the organisation's future state, and that enable its evolution
- implementing enterprise architecture working practices to support and enable iterative/agile working
- interpreting business goals and drivers
- documenting and communicating constraints, standards and guiding principles necessary to define, assure and govern the required evolution
- using architectural models and processes to facilitate changes in the organisation's structure, business processes, information or data, business systems and infrastructure
- describing where and why the enterprise will benefit from cloud-based services.
