A strong demo explains the user problem, shows the important path and handles failure honestly. Recovery is part of the product story.

Inspect a demo plan

The delivery lab defines a local-only fictional plan.

python
from delivery_cases import demo_recovery_case

result = demo_recovery_case()
assert result["normal_and_failure"] is True
assert result["recovery_present"] is True
assert result["plan"]["timebox_minutes"] == 8
assert result["external_deployment_claim"] is False

Rehearse with the exact release and versioned synthetic fixtures. Preflight credentials, network, screen sharing, data reset and monitoring. Script the narrative around user decision, evidence and limitations rather than every feature.

Show one exception and recovery deliberately. Keep a recorded normal path or screenshots as labelled backup, but state when the live environment failed. Do not switch to hidden mocks without disclosure. End with results, unresolved risk and next decision.

The FDE for Freshers course includes recorded and reviewed client-demo roleplays.

Exercise

Prepare an eight-minute capstone demo, disconnect one dependency at minute four and recover using the runbook. Review the recording against a rubric.
