Control charts,not a red-amber-green cell.
Safety performance indicators on real Statistical Process Control charts, with Western Electric rules that separate a genuine drift from ordinary noise. Alerts fire on a rule breach or a target miss, leading and lagging indicators sit side by side, and a library of 610 indicators ships ready to activate against your operation.
A drift trips a rule, not a hunch.
Indicators run on control charts with Western Electric rules, so a signal means the process actually moved, not that a monthly number looked high. Alerts distinguish a rule breach from a target miss, and every indicator ships from a library instead of a blank spreadsheet.
The capabilities, on one record.
Every indicator on a control chart with Western Electric rules, so noise and signal are told apart.
A rule breach fires an SPI alert; a threshold miss fires an SPI target. Two signals, not one vague flag.
Precursor indicators sit beside outcome indicators, so drift is visible before the outcome arrives.
The 610-indicator library ships ready to activate, mapped to the hazards each one watches.
Real records, one reference each.
Every record carries a stable reference and a source on every field. Nothing is silently overwritten, and the trail is the record.

Western Electric rules separate signal from noise
An alert breach and a target miss are different signals
Leading indicators sit beside lagging ones
It links to the rest of the graph.
Drift is computed, not eyeballed.
Statistical Process Control with Western Electric rules, watching indicators tied to named barriers. A trend is declared by the math, before the event.
The signal fired a month before the tug moved. The next chapter computes what all of this does to the risk picture the executive signs.
