Quality & SPC

Catch drift before it becomes scrap

Built-in SPC with X-bar/R, X-bar/S, I-MR, p-chart, and c-chart. Western Electric rules fire alerts the moment your process signals instability.

In-process measurement capture

Measurement inputs are part of work instruction steps. Operators enter values during the process — not on a separate paper inspection form. Data is timestamped to the operation, linked to the lot or serial, and immediately available for SPC analysis.

Automatic control limit calculation

Qontiv calculates UCL, LCL, and sigma from your historical process data. As more measurements accumulate, limits update automatically. You can lock limits to a baseline period for stability-comparison purposes.

Western Electric rules

All eight Western Electric / Nelson rules are evaluated continuously. Violations generate alerts routed to the assigned quality engineer or supervisor — in real time, not at shift end.

Capability indices

Cp and Cpk are calculated for every characteristic with spec limits defined. The capability summary view shows which characteristics are marginal and deserve process improvement attention.

Lot and serial genealogy

Every measurement is linked to its lot or serial through the complete production genealogy. Containment queries for a suspect lot pull the complete inspection record in seconds.
