Reusable decision tool
Build the evidence pack
Check the work that must be complete before a decision.
Start with the front-desk job
Document hours, greetings, locations, caller types, common questions, fields to collect, calendars, urgent cases, prohibited actions, and who receives each transfer.
Verify whether the product includes a number, ports your number, forwards calls, handles simultaneous calls, and preserves context during transfer.
Protect the customer journey
Test names, addresses, dates, confirmation numbers, rescheduling, angry callers, unclear speech, and requests outside policy. Require read-back before consequential writes.
Review recording notice, consent, retention, caller disclosure, accessibility, and emergency-call handling for your jurisdictions.
Take this to every provider
