Learn how SPC separates normal variation from action signals in safety dashboards before leaders overreact to TRIR, DART, and near misses.
Near-miss quality matters more than report volume when EHS managers need early warning on serious exposure, weak controls, and silent operational risk.
Study the metrics mechanism behind Andreza Araújo's PepsiCo accident-ratio result and learn how leaders turn safety KPIs into field control.
DART rate can reveal serious work restrictions, but only when EHS teams separate medical classification from real control failure.
Observation quality exposes whether safety conversations are reducing risk or merely producing comfortable dashboards for leaders.
Audit safety KPIs in 30 days by testing decision use, leading indicator quality, serious-risk exposure, reporting incentives, and denominator discipline.
Safety incentive programs can improve attention or quietly suppress bad news. Use seven tests to keep rewards from hiding serious risk.
Safety culture ROI is not proven by slogans or injury rates alone. Use seven financial and operational metrics that show whether prevention changed the work.
Underreporting in safety hides weak signals when dashboards reward clean numbers more than honest reporting, supervisor escalation, and control repair.
Corrective action closure proves little unless EHS can show that controls changed, exposure fell, and leaders verified the result in the field.
