In plain language
It plans for things going wrong so a failure is noticed and recovered instead of silently dropping data.
Example
If the CRM is down, the workflow retries three times, then posts the record and error to an alerts channel.

Common misconception
Turning off error notifications is not error handling; a failure nobody sees still loses data.
Implementation guidance
Decide per step whether to retry, skip, or stop, send actionable alerts, log the failing input, and make reprocessing safe with idempotency.
