From chaos to control, applying Lean methods to cyber-physical systems
summary
A large e‑commerce sorter starts at ~5,000 cartons/day with 30% jackpot (recirculation/no‑reads) and is driven down to ~3–5% over ten months by joining software and physical observability, correlating scanner images, camera footage and event logs, and mapping physical IDs to software IDs. Daily slices show root causes (no‑read, carton‑not‑found, no‑destination); tools include Grafana Cabana daysdog for metrics plus scanner photos and cameras. Remedies are cross‑functional fixes, shift workshops, simulated failures, post‑mortems and gemba style on‑floor diagnosis, which prove effective.
