The job of an Enterprise Architect is to identify methods, tools and platforms that allow:
- business planners within an Enterprise to build, sustain and augment competitive advantage,
- business managers within an Enterprise to achieve operational efficiencies and effectiveness,
and to confirm the implementation of said methods, tools and platforms.
What is Enterprise Architecture?
From the perspective of the Enterprise Architect, Enterprise Architecture is a practice, detailing the work that Enterprise Architects carry out or cause to be carried out to produce Enterprise Architectures.
From the perspective of all others, an Enterprise Architecture is a deliverable.
Business Managers look to Enterprise Architects to provide them with platforms that provide easy access to context-situational appropriate methods and tools to manage businesses.
One set of methods, tools and a platform is required for business planners building competitive advantage, a second, different, set of methods, tools and platforms is required for operations managers seeking to achieve operational efficiencies and effectiveness.
