A definition of Enterprise Architecture is addressed in 2 constituent parts – enterprise and architecture.

The Open Group defines ‘enterprise’ as follows:

An ‘enterprise’ is any collection of organisations that has a common set of goals and/or a single bottom line. In that sense, an enterprise can be a government agency, a whole corporation, a division of a corporation, a single department, or a chain of geographically distant organisations linked together by common ownership.

Gartner define ‘architecture’ as follows;

1. The grand design or overall concept employed in creating a system, as in the architecture of a city or a customer information system; also “an abstraction or design of a system, its structure, components and how they interrelate”
2. A family of guidelines (concepts, policies, principles, rules, patterns, interfaces and standards) to use when building a new IT capability.

Enterprise Architecture is designed to ensure alignment between the business and IT strategies, operating model, guiding principles, and the software development projects and service delivery.
By taking a global, enterprise-wide, perspective across all the business services, business processes, information, applications and technology, Enterprise Architecture ensures the enterprise goals and objectives are addressed in a holistic way across all the application development projects and their deployment into production.

    I find that definitions that are helpful need to answer the what, how and why questions in combination. So, a helpful definition of EA goes beyond what you have described here.

    In my practice of EA, it has been about describing the intended operating model of an enterprise and building the change program to realise this model.

    It becomes a means of providing support to business change investment decisions which typically include an element of systems investment.

    That, for me, describes a little more of the what and why.
