How can I measure the cost of manual exceptions in the order-to-cash cycle?

[MarkR]

I’ve been mapping our order-to-cash cycle and hit a wall trying to quantify the actual cost of each manual exception. We track the time spent, but I’m struggling to account for the hidden drag on the team’s capacity for other tasks. Has anyone found a reliable way to measure this kind of operational leakage?

We started logging not just the time to fix an exception, but the ripple: who touched it next, how long they paused others, and how long the downstream work waited. It wasn’t precise, but we saw about 15–25 minutes of lost focus per exception and a small backlog uptick the next day. Then we tried a rough multiplier to translate ripple into hours of capacity lost per week. It helped justify a quick tweak in the process.

I did a quick survey with the team after a handful of incidents and compared the time to complete the tasks that followed. The numbers wobbled, but there was a noticeable bump—roughly 10–20% longer cycle time for those downstream items after an exception. We used that as a proxy for capacity leakage, even though I’m not sure it’s precise.

Maybe we’re chasing a symptom. Could the real bottleneck be misaligned priorities or a policy rule that sparks exceptions? I keep wondering if the leakage is more about volume and context switching than the per‑exception cost.

We kept it simple: set a 24 hour reply SLA for exceptions, tagged them by severity, and watched the backlog. After two sprints the urgent queue shrank a bit, but I’m not convinced that was the root cause or that it will stick.
