/ use case 003 · sop adherence

Was the procedure
actually followed?

Cleaning cycles, assembly steps, torque sequences, machine resets, hand-washes — every SOP your operation runs has steps that have to happen, in the right order, for long enough. Darkfield watches every cycle and produces a PASS / FAIL audit per event, with the clip attached.

/ what we detect

Four things, watched continuously.

a / step detection

Did each step actually happen?

Detect when each prescribed step — floor wash, soaping, disinfection, hand-wash, fastener torque, weld, panel placement, machine reset, batch changeover — starts and ends, per camera per shift.

b / duration check

Did it last long enough?

Compare the measured duration against the SOP minimum. A 5-minute disinfection that finishes in 1:20 is a FAIL. A torque-tighten that lasts 0.4s instead of 1.2s is a FAIL. Logged automatically with the clip.

c / sequence check

Were the steps in the right order?

SOPs prescribe sequence — wash → soap → disinfect, or fasten → torque → label, not the other way round. The state machine flags out-of-order events, missed steps, and gaps that exceed tolerance.

d / frequency check

Was it done often enough?

Hand-wash every 30 minutes. Equipment reset every batch. Quality check every tenth unit. The platform tracks cadence per camera per shift, and flags anyone falling behind.

Looking for PPE checks (hi-vis, gloves, hairnets, masks)? That's a separate use case — see PPE compliance.

/ example morning audit

What an SOP audit
actually looks like.

A real morning audit Darkfield generates from a single overhead camera. Five 5S categories, every checklist item PASS / FAIL with timestamp and observation. Drops into the operations manager's inbox before the shift ends.

/ the data table

Every cycle, a row.

Each row is a single SOP event with the verdict, the duration, and a clip link. Aggregated daily / weekly / monthly into a downloadable compliance report.
