True Simplification change - reduce investment Incremental change - additional value from existing investment Re-architecting change - create new value for exploitation

Reference: "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."

Approach The Change Management Process The approach is based on classifying required architectural changes into one of three categories: Simplification change: A simplification change can normally be handled via change management techniques. 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, by a requirement to derive additional value from existing investment; and a re-architecting change, by a requirement to increase investment in order to create new value for exploitation. https://pubs.opengroup.org/architecture/togaf8-doc/arch/chap14.html

Correct Answer 15.5.2 Enterprise Architecture Change Management Process The approach is based on classifying required architectural changes into one of three categories: 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 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.
