A statewide program proposes replacing every departmental data system in one cutover weekend. What modernization approach is more sustainable?
Select an answer to reveal the explanation.
Short Explanation
Rebuilding the whole bridge overnight while traffic is still rolling is a brave story and a bad plan. Peel the old away piece by piece—strangler or incremental modernization—so citizens keep getting service while architecture improves.
Full Explanation
Incremental modernization, including strangler patterns that gradually replace legacy capabilities behind stable interfaces, reduces operational and delivery risk compared with all-at-once rewrites. Big-bang replacements concentrate failure modes and rarely account for hidden couplings. Sustainable architecture change plans coexistence, sequenced cutovers, and measurable interim states.
