Here's a simple 10-point list on keeping automation solid in production:
1. Attach error notifiers: no silent failures. If something breaks, you should know in minutes, not when a customer complains.
2. Log everything meaningful: not just errors, but key steps too. When something goes wrong at 2am, you want a trail to follow.
3. Add retries with backoff: networks blip, APIs rate-limit, servers hiccup. A dumb retry with a small delay fixes half your "failures."
4. Set timeouts on everything: never let a step hang forever waiting on a dead connection or a stuck process.
5. Validate inputs before acting: garbage in, garbage automated. Check the data shape before your script trusts it blindly.
6. Make it idempotent: if a job runs twice by accident, it shouldn't duplicate orders, send double emails, or corrupt records.
7. Have a staging mode: test the automation on fake or sandboxed data before it touches anything real.
8. Set alerts on abnormal behavior, not just errors: a script can "succeed" and still be wrong, like sending 10x the usual emails or processing zero records when it should've processed thousands. Track volume and pattern, not just pass/fail.
9. Monitor rate limits and quotas: automation loves to hit API limits at the worst possible time. Track usage before it fails.
10. Review and prune regularly: automations rot. APIs change, business rules shift. Revisit them every few months so they don't quietly go stale.
