What is the best way to collect OEE data?
The best way to collect OEE data is through a "Visibility Trifecta" approach that combines automated machine signals (PLC/IoT) with operator context and AI-powered Computer Vision to ensure 100% accuracy and zero data blind spots.
Standalone methods, like purely manual logs, fail because they cannot capture the high-frequency micro-stops that define high-speed manufacturing.
By moving to a unified System of Action, you ensure that your data collection directly triggers your maintenance execution.
1. Manual OEE Collection: The "Pencil Whip" Trap
Manual OEE collection relies on operators to record downtime events on paper or in basic spreadsheets.
For Mike (the Tactical Manager), this is a nightmare of "Pencil Whipping," where data is entered at the end of a shift based on memory.
Manual logs are notoriously inaccurate for "Six Big Losses" like minor stoppages or reduced speed, which are often too fast for a human to track.
This method turns your OEE software into a passive "System of Record" that reports on what people think happened, not what actually happened.
2. Automated PLC Connectivity: The Foundation of Truth
Direct machine connectivity pulls signals (Cycle Start, Stop, Count) directly from the machine's PLC or an IoT gateway.
This method provides absolute accuracy regarding the "When" and the "Duration" of every downtime event.
However, a PLC signal is limited; it can tell you a machine stopped, but it cannot tell you the operator was waiting for a material delivery.
For Paula (the Strategic Leader), PLC data is the essential baseline for calculating the Value Fulcrum, ensuring that maintenance effort is aligned with actual runtime.
3. Computer Vision: Capturing the "Invisible" Loss
Computer Vision is the most advanced data collection method, using AI-powered cameras to "see" production events that sensors miss.
Fabrico’s Inefficiencies Zoom-In module captures visual proof of micro-stops, jams, and manual interventions.
When the system detects a performance drop, it flags a video clip, allowing Mike to "Zoom-In" and see the exact root cause.
This eliminates the "Blame Game" between shifts and provides the visual truth needed for high-impact Continuous Improvement initiatives.

The Fabrico Framework: Achieving 100% Visibility
Fabrico does not force you to choose one method; we unify all three into a single Unified Data Intelligence layer.
By combining machine signals, operator inputs, and Computer Vision, we ensure that no loss remains hidden in your factory.
This unified dataset allows Tom (the Technician) to receive a Work Order on his mobile device that includes the OEE trend, the operator note, and the video clip of the failure.
Closing this loop is the fastest way to reduce your Maintenance Cost per Unit and increase your total plant throughput.
As you build this clean data layer, you are preparing your facility for the Fabrico Agent (AI Roadmap), which will eventually automate these diagnostic cycles.
Stop guessing your OEE. Start seeing the truth with a System of Action.
