The Enterprise Architect role starts from the first day of Engagement where Enterprise Architect can look at a whole as an Enterprise Organization or single department in an Organization or subdivision within a Department (depends on how the organization needs to re-align its business and IT)

The Enterprise Architect needs to analyze horizontally Across the Enterprise Organization or Enterprise Department or subdivision etc.

During EA engagement, the Enterprise Architecture captures The Essentials of the business, the IT and their evolution, and below are some Points Which need to ask:

• How to provide a Better support for business by The IT system?
• Witch Organizations and IT resources may or should Be metalized?
• How to increase The contribution of business Process to organizational objectives?
• How to transform IT goals and requirements into Architecture enabling consistent IT Transformation decision?
• How to impulse The necessary dialogue between All the technical architects working in IT The system includes application architect And an infrastructure architect?
•  How to deal with The technological evolution and Corresponding opportunities with business?
• Which policies, Procedures,, and IT resources Are required to support the core business Functions? Etc.

By considering above mentioned objectives, the role and Responsibilities Which EA needs to carry out are:

• Vision Definition
