• Error budget: allowed unreliability, 100% minus the SLO. It turns reliability into a shared, spendable resource.
• A policy states thresholds and consequences in advance: for example, over 50% spent, extra review of risky changes; exhausted, freeze non-reliability releases until recovered.
• Product and engineering agree it before it is needed; leadership backs it.
• Exceptions are explicit and logged; a budget with no consequences is decoration.
