Structure

Domain A consists of the following phases:

• Phase A-A: Develop the Architecture Vision V1
• Phase A-B: Develop the Business Architecture V2
• Phase A-C: Develop the Information Systems Architectures V2:
  • Phase A-C-A: Develop the Data Architecture
  • Phase A-C-B: Develop the Applications Architecture
  • Phase A-C-C: Develop Information Systems Type Views
• Phase A-D: Develop the Technology Architecture V2

Closure on Domain A will be when:

1. The strategic deliverables have been completed and agreed by all concerned, including the Board.

2. The next domain has been fully activated.
