  1. Architecture Change Management The goal of an architecture change management process is to ensure that the architecture achieves its original target business value. This includes managing changes to the architecture in a cohesive and architected way.

  2. Drivers for Change • Strategic, top-down directed change to enhance or create new capability (capital) • Bottom-up changes to correct or enhance capability (operations and maintenance) for infrastructure under operations management • Experiences with the previously delivered project increments in the care of operations management, but still being delivered by ongoing projects

  3. Lessons Learned • A lessons learned process ensures that mistakes are made once and not repeated

  4. Why changes ? • New technology reports • Asset management cost reductions • Technology withdrawal • Standards initiatives

  5. Changes • Business drivers for architecture change, including: • Business-as-usual developments • Business exceptions • Business innovations • Business technology innovations • Strategic change

  6. Types of changes • Simplification change: A simplification change can normally be handled via change management techniques • Incremental change: An incremental change may be capable of being handled via change management techniques • Re-architecting change: A re-architecting change requires putting the whole architecture through the architecture development cycle again

  7. Keep this in mind • A good rule-of-thumb is: • If the change impacts two stakeholders or more, then it is likely to require an architecture redesign and re-entry to the ADM. • If the change impacts only one stakeholder, then it is more likely to be a candidate for change management. • If the change can be allowed under a dispensation, then it is more likely to be a candidate for change management.
