Fault-to-Fix: Turning Detected Downtime Into a Closed Work Order

Key takeaways

• Fault-to-fix is the closed loop from the moment a machine stops to the moment a verified work order closes the issue. Most plants own both ends (downtime data and a CMMS) but have nothing automatic connecting them.
• The loop usually breaks at the handoff: a stop is logged, but a person has to notice it, decide it matters, guess a cause, and open a work order by hand. That delay is where repeat failures hide.
• An automated loop detects the stop, captures the true cause, and dispatches a work order with the context attached, so the technician arrives knowing what happened instead of starting from a blank ticket.
• The hard part is not the alert, it is the cause. A loop that fires a generic "line down" alert still leaves diagnosis to a person; the value comes from attaching an accurate reason to every stop.

What fault-to-fix actually means

Fault-to-fix describes the full path a single downtime event travels: detection, diagnosis, dispatch, repair, and verification. In a healthy loop, each step hands clean data to the next without anyone re-keying it. In most plants the path is split across disconnected systems, and the gaps between them are filled by people remembering to act.

The symptom is familiar. The OEE board shows a stop. The maintenance team finds out at the morning meeting, or when an operator walks over. By the time a work order exists, the machine is running again and the real cause is a guess. The event gets logged as a minor stop, and the same fault returns next week.

Why the loop breaks

The break is almost always at the detection-to-diagnosis handoff. Detecting that a machine stopped is easy; sensors and counters do it automatically. Knowing why it stopped is the hard part, and that is the step most systems leave to a human standing at the line.

• The reason is missing or wrong. An operator picks the nearest reason code under time pressure, so the data that should drive the fix is unreliable from the start.
• The work order is manual. Someone has to decide a stop is worth a ticket and open one, which means short repeat stops never generate a record.
• Context is lost. The technician gets a ticket that says "Line 3 down" with none of the surrounding data, so diagnosis starts over from zero.

For how stops get classified in the first place, see downtime versus uptime.

The automated fault-to-fix workflow

1. Detect. The stop is captured automatically from the equipment signal or the OEE system, with an exact timestamp and duration.
2. Diagnose. A true cause is attached to the stop rather than a guessed reason code. This is where computer vision and event context do work a rushed operator cannot.
3. Dispatch. A work order opens automatically, pre-filled with the asset, the cause, and the production context.
4. Repair. The technician arrives with the diagnosis already in hand and records what was actually done.
5. Verify. The closed work order links back to the original downtime event, so the same fault recurring is visible immediately.

The work order management system is the backbone of steps three through five, and the preventive maintenance schedule is where recurring faults get designed out.

Manual versus automated fault-to-fix

What to look for in a fault-to-fix platform

• Accurate cause capture, not just alerts. An alarm that says "down" is not enough. Look at how the platform determines the reason without relying on a rushed manual entry.
• One data model for OEE and maintenance. If downtime lives in one system and work orders in another, the loop has a seam where data is lost. A single source of truth removes it.
• Automatic work-order creation with context. The ticket should carry the asset, cause, and production state without re-keying.
• Closed-loop verification. The closed work order should link back to the downtime event so recurrence is measurable.
• Works on mixed and older lines. The loop should deliver value before every asset is new or fully instrumented.

How Fabrico closes the loop

Fabrico is built as one platform for OEE and CMMS, so a detected stop and the resulting work order share the same database instead of crossing an integration seam. When a line stops, Fabrico uses computer vision to capture the true cause of the downtime rather than leaving it to a reason code, then opens a work order with that cause and the production context already attached. The closed work order links back to the original event, so a fault that keeps returning is visible rather than buried. Fabrico is built and hosted in the EU with data residency in mind and is ISO 27001 certified. To see the loop run against your lines, book a demo.

Frequently asked questions

Is fault-to-fix the same as predictive maintenance?

No. Predictive maintenance tries to act before a failure happens. Fault-to-fix is about what happens after a stop occurs: capturing the true cause and turning it into a closed, verified work order quickly. The two are complementary, but fault-to-fix delivers value even on assets with no predictive model.

Do we need new sensors on every machine?

No. The loop should deliver value on mixed and older lines using existing signals and the OEE event stream. Full instrumentation can come later; it is not a precondition.

What makes the loop break most often?

The detection-to-diagnosis handoff. Detecting a stop is easy; attaching an accurate cause is the hard part, and a generic alert still leaves diagnosis to a person. A loop is only as good as the cause data it captures.

How is this different from a standalone CMMS?

A standalone CMMS manages work orders but usually relies on someone opening them by hand. Fault-to-fix connects the downtime event to the work order automatically, so short repeat stops that would never get a manual ticket still generate a record.
