The ROI of digital ergonomics: a before/after case study
How a mid-sized warehouse cut their average peak REBA score from 9 to 5 in one quarter by acting on the data their floor walks had been collecting all along.
This case study describes a composite scenario based on patterns we’ve seen across pilot customers. Details are illustrative but representative.
The starting point
A mid-sized distribution center (~180 workers, mostly pick & pack) was running paper REBA assessments quarterly. The safety manager spent ~4 hours per assessment between observation, scoring, and write-up. Roughly 12 assessments per quarter.
The pain points were familiar:
- Assessments piled up unprocessed. By the time scoring was done, the line had moved on.
- Two assessors produced different scores for the same task.
- Management didn’t see trends — just individual reports that landed in the inbox and got filed.
- When OSHA showed up to investigate an unrelated incident, assembling the ergonomics binder took two days.
The change
The team switched to ErgoVision. Same methodology (REBA), but the phone did the scoring. Observation-to-PDF dropped from 4 hours to 15 minutes.
With time freed up, the safety manager tripled assessment frequency— from 12 per quarter to 36. The dashboard immediately surfaced something paper-era reporting had missed: three stations on the repack line were consistently above AL3. The reach distance to the top-row carton stack was the common cause.
The intervention
The team installed three gravity-fed slides at those stations ($4,200 total, including labor). The estimated payback — based on the facility’s historical MSD claim costs — was 6 months.
The after
Re-assessment after 6 weeks of the change:
- Average peak REBA on those three stations: 9 → 5.
- Trunk peak angle: 62° → 31° (the reach was the biggest contributor).
- Time in AL3+: 28% → 4%.
The before/after chart fit on one slide. Plant leadership approved the same retrofit for the other two warehouses that quarter.
The compounding benefits
- Documentation. Every assessment is now timestamped, signed, and exportable. The next compliance inquiry takes minutes, not days.
- Trend reporting.Management asks for the quarterly trend chart now — it’s a standing agenda item.
- Worker buy-in. Showing workers the score drop on their own station built trust in the program.
The honest caveats
Digital scoring doesn’t replace a trained ergonomist’s judgment. The biggest wins come from doing more assessments and acting on them faster, not from any magic in the scoring algorithm itself.
Also: AL4 findings still need a human review. ErgoVision flags them; the safety pro decides whether the answer is engineering, admin, PPE, or a redesign.
