Exam OG0-093 topic 1 question 20 discussion

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, or it may require partial re-architecting, depending on the nature of the change (see 15.5.3 Guidelines for Maintenance versus Architecture Redesign for guidelines) Re-architecting change: a re-architecting change requires putting the whole architecture through the architecture development cycle again

The Change Management Process Simplification change: A simplification change can normally be handled via change management techniques. --- Guidelines for Maintenance versus Architecture Redesign For example: If the change is at an infrastructure level - for example, ten systems reduced or changed to one system - this may not change the architecture above the physical layer, but it will change the Baseline Description of the Technology Architecture. This would be a simplification change handled via change management techniques. https://pubs.opengroup.org/architecture/togaf8-doc/arch/chap14.html

15.5.2 - Enterprise Architecture Change Management Process Another way of looking at these three choices is to say that a simplification change to an architecture is often driven by a requirement to reduce investment; an incremental change is driven by a requirement to derive additional value from existing investment; and a re- architecting change is driven by a requirement to increase investment in order to create new value for exploitation.

Correct Answer simplification change - to an architecture is often driven by a requirement to reduce investment incremental change - It is driven by a requirement to derive additional value from existing investment re-architecting change - It is driven by a requirement to increase investment in order to create new value for exploitation.

If the change is at an infrastructure level — for example, ten systems reduced or changed to one system — this may not change the architecture above the physical layer, but it will change the Baseline Description of the Technology Architecture; this would be a simplification change handled via change management techniques - Answer is "E"
