You choose. I map the process, find the constraint, and build what clears it, scoped to the bottleneck in front of you, not a platform you will grow into. From there it is one of three things: a written handover document and nothing further, hands-on training so your team learns the system on their own real work, or an ongoing concierge term while you find your feet. Whichever you pick, the system and its documentation are yours to keep.
