foolproof
Impossible to bungle
Foolproof describes something designed so simply or reliably that even a fool couldn't misuse it or cause it to fail: a foolproof plan, foolproof instructions.
The word implies that failure has been engineered out—no skill or intelligence required.
The system isn't foolproof, but it catches most errors.
