Choose a bounded first workflow.
An internal knowledge assistant, administrative drafting step or enquiry summary has different risks from an autonomous agent. Define the inputs, expected output, authorized data and human review before a pilot. Avoid sensitive or high-stakes workflows without qualified review.
Test ordinary days and awkward exceptions.
Evaluate realistic cases, incomplete inputs, conflicting sources and unsupported requests. Set budget caps, fallback behavior and a way to stop the workflow. The acceptance criteria should say when the assistant must ask a person rather than guess.
Make adoption part of delivery.
Document what the system can do, what staff must check and who handles a failure. Train the users, assign an owner and agree whether BGE monitors the implementation. Model usage, vendor licenses and future changes are separately scoped.
