Turning a multi-shift factory's punch logs into audited exceptions

A manufacturer's HR team replaced a full day of manual timesheet reconciliation with a short, evidenced exception list it can sign off in minutes.

Background

The manufacturer runs hundreds of staff across rotating shifts. Every month, HR reconciled attendance by hand from three systems that rarely agreed: punch logs, leave applications and overtime requests. The pass took most of a day, still missed cases, and was hard to defend when an employee disputed a deduction.

The rules that decided what counted as an exception lived in a few people's heads and a set of spreadsheets, so the same situation could be judged differently from month to month.

Business challenges

Three sources, never aligned

Punch, leave and overtime each told a different story for the same day.

Rules lived in people's heads

Applied by hand, they were inconsistent and left with whoever knew them.

A full manual pass each month

Slow, easy to miss a case, and hard to defend in a dispute.

One long undifferentiated list

Everything looked equally urgent, so nothing was actionable.

Solution

We encoded the rules HR already trusted into an engine that ingests the three daily sources and produces a typed, tiered exception list: high, medium and information, each with the punches, leave and overtime that triggered it attached as evidence.

Nothing is a black box. Every flag links back to the raw records, HR confirms a short list, and the rules are versioned: they only change when HR signs the change, so the engine never drifts from policy.

Rules locked with HR over weeks, then monthly in minutes

Rapid design & deployment

One expensive problem, proven before it scales. The A1 to POC method, run in weeks not quarters.

A1 · Confirm the goal
Decide which exceptions matter, agreed with HR.
A2 · Audit the data
Map the three sources and the shift tables.
A3 · Design the rules
Type and tier the exceptions, attach evidence.
POC · Run real months
Validate against months HR already knows, then tune.
Handoff · Sign-off flow
Ship versioned rules and the monthly sign-off.

Governance & standards

We design and deploy to the ISO/IEC 27001 (information security) and ISO/IEC 42001 (AI management system) frameworks. Data stays where it should, decisions that carry real cost keep a human in the loop, and every model call is logged for audit.
