The key term being discussed is continuous improvement. Continuous improvement, also known as Kaizen, refers to making incremental improvements to processes on an ongoing basis rather than single large changes. It is a core part of lean manufacturing and aims to eliminate waste through continuously improving processes. The seven main types of waste are overproduction, over processing, excess inventory, defects, transportation, wasted motion, and waiting time, with an eighth being unused employee creativity. Continuous improvement seeks to enhance value and quality by systematically making small, incremental changes.
