Enterprise Architecture FAQ - Via Nova Architectura - Digital, Enterprise, IT Architecture

EA is the Architecture i.e. the structure and blueprint of the Enterprise describing the current and future states of the Enterprise in terms of operation and human and technology resources and the Enterprise transformation roadmap.

What is the purpose of EA?

The EA, as a blueprint, is employed by each and every stakeholder for own work purposes. For instance, IT people document, analyse and roadmap the IT. Finance people document the budget and cost flows. HR associates people, skills and remuneration to business functions and operation. All these views would be linked and traversed on the EA representation.

Why EA?

EA is a reusable asset in the Enterprise competitive race. Overall, EA enables the Enterprise simplification, integration, operational improvements, resource saving, assets management, enhanced agility through modular services, coherent roadmapping... and in general enables a superior management of the Enterprise and its growing complexity.

Who does EA?

The Enterprise Architect specifies the EA framework and coordinates the EA work. The Enterprise domain owners model and document their own Enterprise parts as Views. EA is a collective effort.

What should EA also do?

EA should coordinate and document the many fragmented or loose coupled Enterprise developments such as SOA, IT Architecture, Application Integration (EAI), ITIL efforts and many independently performed efforts such as Enterprise alignment to Business Strategy and Goals, compliance to regulation, Business Process Improvement, Six/Lean Sigma, Mergers & Acquisitions and Outsourcing and Cloud.

Ultimately, EA becomes the Enterprise Knowledge database.

What does EA in practice?

EA is used for the discovery of IT systems landscape and its roadmapping. Once this done, many business as usual EA efforts are reduced to Architecture Review Boards's solution architectures, reviews which are seldom based on an EA since it is seldom modelled.

Why an EA framework?

The EA framework links together in the EA whole the parts of the Enterprise modelled and designed independently by stakeholders so that the EA can be navigated for process analysis, impacts on resources, strategy mapping and so on. The framework offers predictability, repeatability to EA developments.
