This pitfall happens when digital services cannot gracefully degrade on failure, when production deployments aren't consistently applied in all environments, and when the telemetry toolchain isn't fully automated. Excessive BAU can be hard to detect, because product teams don't always track operational rework in a ticketing system like Jira. Product team members might fix intermittent alerts, deployment failures, infrastructure errors etc. without a ticket. It can be spotted by measuring the percentage of time product team members spend on planned work, each week.
