Overhead and delay both cost time, which is exactly why they're easy to blur -- but one is a one-time event and the other is a recurring pattern, and treating one as the other misdirects the fix.
A delay is time lost on a specific occasion. Overhead is the additional recurring work required around the main task -- a different, ongoing problem, not a one-time timing loss.
One occasion vs. every occasion
A one-time delay is resolved by expediting or escalating the specific shipment or task that's stuck. Recurring overhead is resolved by redesigning the process itself, since it shows up on every request, not just one.
"'The shipment was delayed two weeks because customs held the paperwork' is a delay -- a specific, one-time timing loss, not a recurring process cost."
"A process where every request has to pass through three separate review steps adds recurring overhead on every single pass through it, unlike a shipment that is delayed just once."

Start learning for free →The customs example is contained to one shipment, one occasion, one specific cause. The review-steps example recurs identically every single time a request moves through the process -- that repetition is the entire signal that you're looking at overhead, not a delay.
Why the distinction changes the fix
Treating a delay as overhead (or the reverse) misdirects the fix. Escalating a shipment doesn't help a recurring three-step review process -- the review steps will still be there next time. And redesigning a process doesn't help a one-off customs hold -- there's nothing structural to redesign; you just need to expedite the specific stuck paperwork.
Don't describe a one-off shipment or task delay as "overhead" -- overhead names work that recurs on every pass through a process, while a delay is lost time on one specific occasion that expediting can fix.
Practice scenarios
Practice using overhead in situations like:
- deciding whether a stuck shipment needs escalating or a broken process needs redesigning
- describing a repeated process cost accurately instead of calling it a delay
- recognizing when a "delay" is actually happening on every single request
Useful practice phrases:
- "[Shipment/task] was delayed because [specific cause]" (one-time).
- "[Process] adds recurring overhead on every pass through it" (ongoing).
- "This needs to be escalated" vs. "this process needs to be redesigned."
A delay happens once and gets expedited away. Overhead happens every time and needs redesigning.
Naming which one you're facing tells you exactly what to do next.
