An automation that works on launch day is easy. The real test is week eight, when something changes and nobody is watching.
What a reliable automation does
- It never does the same job twice. If it runs again, nobody gets a second invoice or a duplicate email.
- It speaks up when it fails. Problems go to a named person, not a log nobody reads.
- It can be done by hand. There is a short written fallback if it ever needs switching off.
- It notices silence. It tells you when something that should have happened did not.
Ask any supplier: "How will I know if it stops working?" A good answer is specific.
