Objectives of Phase H: Architecture Change Management are:

  • Ensure that the architecture lifecycle is maintained
  • Ensure that the Architecture Governance Framework is executed
  • Ensure that the enterprise Architecture Capability meets current requirements

Drivers for Change

  • Business drivers
    • Business-as-usual developments
    • Business exceptions
    • Business innovations
    • Business technology innovations
    • Strategic change
  • Technology drivers
    • New technology reports
    • Asset management cost reductions
    • Technology withdrawal
    • Standards initiatives

Change Management Process

Changes fall into 3 categories:

  1. Simplification change
    • A simplification change can normally be handled via change management techniques.
  2. Incremental change
    • An incremental change may be capable of being handled via change management techniques, or it may require partial re-architecting, depending on the nature of the change (see 16.2.3 Guidelines for Maintenance versus Architecture Redesign for guidelines).
  3. Re-architecting change
    • A re-architecting change requires putting the whole architecture through the architecture development cycle again.
