What is in the checklist
Most OMS implementations hit change orders because gaps were not surfaced before the SOW was signed. This checklist walks through every readiness domain — with specific items per area — so you know your position before the vendor kickoff.

- Order entry → allocation → confirmation → settlement workflow documented end-to-end
- Cross-asset workflow coverage confirmed: equities, fixed income, derivatives

- Manual workaround inventory complete — decision made per workaround: automate, keep, defer
Section 2

If two or more sections land in Mostly Ready or Not Ready, the next step is not another worksheet. Use the $1.5K Risk Scan for executive triage, or the OMS Readiness Diagnostic when the implementation plan needs a full review.
