Rehearse the Happy Path and Edge Cases
Bad demos waste trust. This is the checklist I run through before showing progress to clients — technical and presentation wise.
- staging verification — applied directly to preparing reliable client demos.
- seed data — applied directly to preparing reliable client demos.
- demo script — applied directly to preparing reliable client demos.
- fallback screenshots — applied directly to preparing reliable client demos.
The Working Approach
For Client Demo Checklist Before Every Sprint Review, I kept the implementation narrow: staging verification, seed data, demo script, and fallback screenshots. Every decision tied back to that scope instead of expanding into unrelated admin features.
Have a Backup When Live Demo Fails
Representative code from the implementation — simplified for readability, but structurally what I deploy.
Cron heartbeat file for job monitoring
<?php
file_put_contents('/var/www/app/storage/cron-heartbeat.txt', time());
$last = (int) @file_get_contents('/var/www/app/storage/cron-heartbeat.txt');
if (time() - $last > 90000) {
mail('ops@example.com', 'Cron failed', 'Nightly job did not run.');
}Where This Approach Paid Off
The measurable win for preparing reliable client demos was fewer support messages, not a flashy demo. Predictable behaviour mattered more than feature count.
If I repeated this, I would write the regression checks earlier — especially around the failure paths users hit once, not the happy path.
If You Are Tackling Something Similar
- Start with the exact problem statement for preparing reliable client demos — one sentence, no buzzwords.
- Prioritise staging verification before polishing secondary UI details.
- Validate seed data under realistic data volume, not demo rows.
