Customer audits expose HR gaps: a fix for auto component makers

The auditor halts at the continuity tester on a harness line. How long has the operator run it? Three weeks, she says. He asks for her sign-off. The laminated matrix on the line board shows her as independent. The dojo register in the office holds an unsigned sheet. Biometric punches place her on the crimping section for two of those weeks. A finding is drafted before lunch.

That sequence explains why audits make the list of recurring strains in our guide to people issues at tier suppliers. Customers examine training files, attendance, shift handovers and role clarity because discipline shows there first. A flawless quality manual can sit above a broken people trail.

• Crimping applicator: the crimp-height chart, the pull-test log and who set the applicator this morning.
• Injection press: the boundary sample board for sink marks and flow lines, and whether the visual inspector can explain each sample.
• Grinding cell: the wear offset log, the setting master and who zeroed the bore gauge at shift start.
• Pad curing oven: the cure chart, the loading pattern and the operator's sign-off on that recipe.
• Battery pack station: the torque-sequence card, the insulation tester and who may override a failed reading.
• Cold header: the size-change checklist, the chute purge signature and a sample pulled from the last carton.
• Final inspection: whether the inspector knows she may hold a lot, and whom she informs.

After each station, the auditor walks to the office. Do the dojo register, the line board and the day's roster agree? Disagreement there becomes the finding.

Findings bring corrective action reports, a follow-up visit and management hours. Worse damage happens inside. Supervisors and HR spend Sundays backfilling files and signing sheets after the event. That ink hides the real hole. The untrained tester operator remains on the tester next month. Customers compare audits over years, and repeat people findings weigh on the scorecard when a new part number is being sourced.

• Orphan records. The dojo register, matrix, muster roll and role descriptions each sit with a different desk, or with none.
• Retrospective signatures. Sign-offs are written when someone asks for them, weeks after the assessment.
• Parallel formats. Moulding, harness and machining sections each keep private training sheets that never reach the master file.
• Office hours. HR works days, so night shift practice stays invisible to the people maintaining files.
• In-charges never coached. Shift supervisor training in an auto parts plant seldom covers writing a handover entry or recording a sign-off.

Pick: one operator at random on nights, at a critical station.
Ask: which check does your station need, and where does a doubtful part go?
Joining: date of joining, and was induction signed that same day?
Dojo: trainer, practice dates and sign-off level for this operation?
Line board: does the matrix show the level the dojo register shows?
Roster: was this person rostered here tonight, and who relieves them at tea?
Handover: does last night's log record faults and actions at this station?
Close-out: list each mismatch, the person fixing it and a target date.

A file that survives that trace usually holds a short, predictable set of papers.

• Induction checklist with PPE issue and the safety briefing, signed on joining day.
• Dojo practice log showing hours on dummy boards, scrap terminals or trial shots.
• Sign-off sheet per operation, with assessor, level and date.
• Requalification entries after long leave, transfer or a drawing revision.
• Colour-vision screening for paint and cosmetic inspectors, where the customer expects it.
• Relief pair chart for each critical station and shift.
• Handover book entries naming faults, holds and pending actions.

1. 1

   Give every record one keeper

   HR keeps induction and the master file. The training coordinator keeps the dojo register. Each line in-charge keeps the matrix, and each shift supervisor keeps the handover log.

2. 2

   Sign on the day

   Induction is signed at induction and sign-off at assessment. Anything signed later shows its real signing date.

3. 3

   Link everything to one master record

   Every dojo entry and sign-off points back to one employee record, so the board and the file cannot drift apart.

4. 4

   Run a monthly mock trace

   HR and quality choose three operators, at least one on nights, and work through the template. Mismatches join a tracked list.

5. 5

   Describe critical roles in writing

   Final inspector, setter, gauge room technician and line in-charge, each with decisions they own, including authority to quarantine a lot.

6. 6

   Coach in-charges on entries

   A short floor session on handover notes and sign-off recording. The incoming in-charge then reads the log at every changeover of shift.

Plants that pass calmly treat the mock trace as routine rather than rehearsal. Tidy employee records form the base. Clear role descriptions settle who decides what. The role pages for brake component makers and automotive plastics makers put inspector authority in writing. Our story of a training record that became a quality record shows why auditors care. For the night gap, use a one-sheet handover format.
