Continuous improvement aims to create a culture that eliminates losses at all levels by focusing on accident elimination, quality defects reduction, breakdown reductions, line stoppage reductions, changeover time reductions, and reductions in waste and over-usage. Management buy-in, operator involvement, data collection, and making improvements through small, incremental steps are key to achieving continuous improvement. Common tools for continuous improvement include kaizen, 5S, SMED, BAT, 4M, Why?, TAMMO, and OEE.
