How fresh does your knowledge assistant need to be?
Choose refresh commitments from business consequences instead of assuming every document is live.
Classify the cost of being stale
A holiday schedule and a changing service price do not need the same refresh promise. List the decisions the assistant supports and estimate how a stale source could affect each one. Define a freshness expectation per source class, along with an owner who can approve it. AWS documents synchronization as a separate ingestion operation; the business should make that boundary visible in its own service definition.
Trace the full refresh path
In an illustrative client-support workflow, follow an update from approved document to connector, parser, index, retrieval cache, and answer. Record timestamps at the stages you actually control. Test with a harmless distinctive phrase and verify that the old passage disappears. A green connector status is not enough if the relevant document was skipped or the assistant is still using a cached result.
Workflow at a glance
Plan a stale-content response
If the freshness deadline is missed, mark the source state and choose a safe next step. The assistant might direct staff to the authoritative system or ask the content owner for confirmation. Avoid presenting an old answer with a current chat timestamp that implies current policy. Give support staff a way to identify the affected source and pause only the relevant workflow rather than shutting down every useful function.
Make refresh tests routine
Include added, changed, deleted, and permission-modified examples in regular checks. Measure actual time to usable retrieval, not just job duration. Review the promise when document volume or connector behavior changes. A stricter refresh schedule can increase cost without improving the decisions staff make. The useful target is a documented, testable freshness contract proportionate to the workflow’s needs and consequences.
A freshness dashboard with meaning
Show source status in terms staff understand: last verified update, pending refresh, and blocked content. Avoid a dashboard that lists only infrastructure jobs. Ask an employee to explain whether they can rely on the selected procedure today; if the screen cannot answer that, redesign its status language.
