Fixed cost continues
Labor, equipment leases, and facility overhead don't pause when the line does — they're part of the true cost of an idle line, not just lost output.
Manufacturing
An idle production line burns cost either way.
Manufacturing downtime cost is driven by fixed costs that keep running whether or not the line does — labor, equipment leases, and missed production targets all continue during an IT-driven stoppage. Defaults below reflect an OT/IT convergence profile.

Idle line cost
The line doesn't need to be broken to cost money.
A SCADA, MES, or ERP outage can halt a fully functional production line — the equipment isn't broken, but it can't run without the system coordinating it, and the fixed costs of labor and lease keep accruing regardless.
Supply chain cascade
Missed production targets can cascade into missed shipment windows, pushing cost onto downstream customers and contractual penalties.
OT/IT recovery complexity
Physical equipment and safety interlocks often require manual verification before restart, extending MTTR well past the software fix itself.
FAQ
Manufacturing outage cost, answered.
Questions that come up when sizing the cost of a plant-floor IT or OT outage.
What should I use for the impact-per-hour input?
A common approach is lost production value per hour plus the fixed labor and overhead cost that continues regardless of output — not just the revenue from finished goods.
Why is the default SLA target lower than other industries?
Many plant-floor systems were not originally designed with cloud-grade SLA targets in mind — 99.5% is a common realistic starting point for older OT/IT environments.
Why is MTTR longer for manufacturing?
Physical safety interlocks and equipment verification steps typically extend recovery time beyond what a pure software fix would take.
Should downstream supply chain penalties be included?
Not directly — those are contract-specific. Add an allowance for missed shipment penalties separately if your contracts include them.
