Enterprise Architecture can be viewed from several perspectives by Information Systems professionals. Performing a job task analysis is a way to get a handle on this complex job role.
I would emphasise on the following view points.
View enterprise architecture as a framework for business applications management. The enterprise architecture is arrived at with the participation of senior level members from the systems as well as the business side.
Communicating with the stakeholders on matters such as identifying system context, understanding systemic qualities, planning for risk mitigation for projects, security, service level agreements for systemic qualities are some of the tasks that fit in the architectural tasks.
View enterprise architecture as a layer above the information technology architecture. It is a foundation for operations and business execution. Business processes, information architecture, applications and technology architectures are arrived at based on this foundation.
The core message is that arriving at the enterprise architecture demands the collaboration of mature business and information systems professionals.
Arriving at enterprise architecture is a learning exercise about the operations of the business for the senior executives. It is about commitment to focus and lead the continuous business transformation. Enterprise Architectures uses the benefits of better business processes and technical capabilities due to effective information systems.
