Why Production Operations Need Digital Systems
Spreadsheets work until a production line grows past what one shared file can honestly track. Here's where that line usually gets crossed.

What is it?
This is about the point where a manual, spreadsheet-based process stops being reliable for running a physical operation, and needs to become a proper system instead.
Why does it matter?
A shared spreadsheet works fine when one or two people update it carefully. It stops working once there are multiple people, multiple stages, and real consequences for the numbers being wrong: stock that doesn't match what's on the shelf, a delivery that doesn't match what was scanned, a report that was already stale by the time someone read it.
Real-world perspective
Before RPOMS, the router-refurbishment program I work on ran on spreadsheets. The system replaced that with something that updates stock and dashboards in the same step data is entered, so the numbers reflect what's actually happening rather than what was last typed in.
Key considerations
Watch for the moment when people start keeping their own private copies of a shared sheet to be safe. That's usually the sign.
A digital system doesn't need to be complex to be worth it. It needs to remove the specific failure modes a spreadsheet has: no validation, no single source of truth, no audit trail.
Migrating off a spreadsheet only works if the new system fits how the operation actually runs, not the other way around.
Conclusion
The decision to move off spreadsheets is less about scale and more about whether the numbers can still be trusted.
