Ask a plant what paper costs and the answer is 'nothing, paper is cheap.' The paper is. The people touching it are not. Every handwritten number begins a small career: written at the station, keyed into Excel tomorrow, corrected when the key-in misreads the handwriting, and assembled into a report on Friday. The cost hides because it is spread across a dozen people's partial hours.
The touch-count method
For each record family (quality checks, production counts, downtime logs, batch sheets, receiving paperwork), walk one record through its life and count touches: creation, transport, key-in, correction, aggregation, filing, retrieval. Multiply by records per week and minutes per touch. Honest counts land between three and five touches per record, and the totals surprise everyone.
A worked example
- Hourly line checks: 3 lines × 20 checks/day × 2 min key-in and correction ≈ 14 hrs/week
- Daily production summaries rebuilt in Excel: 3 supervisors × 45 min/day ≈ 16 hrs/week
- Batch sheets keyed and filed: 25 batches/day × 6 min ≈ 12 hrs/week
- Receiving paperwork and COAs filed and later hunted: ≈ 8 hrs/week
- Month-end reconciliations of numbers that never match: ≈ 10 hrs/week averaged
That conservative plant re-keys 60 hours a week, roughly 1.5 full-time equivalents doing transcription, before counting error costs: the mis-keyed weight that becomes a customer deduction, the illegible lot code that turns a trace into an afternoon.
The two costs the worksheet misses
Lag and trust. Data keyed tomorrow cannot stop anything today, every drift runs a shift longer than it should. And numbers that pass through three hands stop being believed, which is why meetings argue about whose spreadsheet is right instead of what to do. These do not fit in the worksheet; they are usually worth more than the hours.
From arithmetic to action
Run the touch-count, then point the total at the fix: station capture kills the key-in touch, machine connections kill the writing itself, and self-writing reports kill the Friday assembly (sequencing in the 90-day plan; category overview in the paperless software guide). Harmony pilots are scoped to exactly this arithmetic: a $15-20K one-time engagement against a re-keying line item that is usually multiples of that per year.
