How do I modernize IBM i dispatch or rating software without disrupting operations?

Scope the project around the dispatch and rating logic as the highest-risk, usually least-documented part of the system, and start elsewhere. A phased approach beginning with a lower-risk edge capability, such as mobile proof-of-delivery capture or document extraction, before touching dispatch or rating directly, reduces the chance of an outage that stops trucks from being dispatched. AI code-explanation tools such as IBM Bob can help a team understand undocumented rating logic before anyone proposes changing it.
