Real system (context)

An operations team faced intermittent cell faults that were difficult to reproduce and trace manually. Legacy controller differences made the troubleshooting process slow and error-prone.

Real workflow (what was done)

The team ingested tag data and logic snapshots to generate a unified signal flow view. They replayed fault pathways in simulation and correlated event timing to likely root-cause branches.

Real outcome (what changed)

This reduced dependency on manual cross-referencing and shortened fault isolation cycles. Engineers could explain system behavior clearly and coordinate fixes with fewer handoffs.
