Gemba walk during Lean audit
confirms measurable improvements across all business-critical dimensions, such as employee engagement, structural stability, sorting quality, equipment reliability, and operational productivity. Four focus factories of Norway’s leading environmental service company are regularly audited to measure Lean progression and correlate maturity with performance, identify opportunities and provide coaching feedback – getting ready for the next improvement cycle.
Industry 4.0 meets Lean
NG’s brownfield operations have been upgraded with latest Industrial Internet Of Things (IIOT) devices to bring existing lines and equipment online. Shredder, sorter, press, shearer, and other key equipment continuously record health and performance data in the central database. Having key information available near real-time allows the operations team to detect and correct deviations much faster than ever before. Lesson learned: Combining Lean thinking with Industry 4.0 technology can be extremely powerful. It allows transforming brownfield operations, bringing them into the 21st century of manufacturing, while unlocking hidden performance gains. Most of NG’s focus factories attained Silver level already (maturity score 3.0 per Lean Factory Audit), while the best plant near Fredrikstad (internal Lean benchmark) is preparing for Silver-Gold now (3.5 maturity score). In average, the four focus factories matured +16%, while raising productivity +25% over the past 20 months alone. The journey continues!
