Lean Manufacturing Terms
Andon is derived from a Japanese term for a type of paper lantern. In manufacturing, Andon systems provide visual feedback to the plant floor. Typically, Andon systems indicate line status, show when assistance is needed (e.g. supervisor or maintenance calls), and empower operators to stop the production process (e.g. for quality issues).

Kaizen is the Japanese term for continuous improvement, a strategy where companies and individuals work together proactively to achieve regular, incremental improvements in the manufacturing process. Kaizen Video Below.
Key Performance Indicators (KPIs) are metrics that facilitate achieving critical goals of the organization. The best manufacturing KPIs are aligned with top-level strategic goals, help expose and quantify waste, and can be readily influenced by plant floor personnel. KPI Video Below.
Single Minute Exchange of Die (SMED) or “quick changeover” focuses on reducing the time it takes to changeover a production process from manufacturing one part to manufacturing the next part – ideally to less than 10 minutes. This enables smaller lots, less inventory, and a faster response to the marketplace. SMED Video Below.
Total Productive Maintenance (TPM) is a holistic approach to maintenance that focuses on proactive and preventative maintenance to maximize the operational time of equipment. TPM blurs the distinction between maintenance and production by placing a strong emphasis on empowering operators to help maintain their equipment. TPM Video Below.
Toyota Production System (TPS) is a manufacturing strategy developed by the Toyota Motor Corporation of Japan over a period of many years. TPS focuses on the complete elimination of waste from the manufacturing process, and is the progenitor of lean manufacturing. TPS Video Below.
Overall Equipment Effectiveness (OEE) is a “best practices” metric for monitoring and improving the efficiency of manufacturing processes. It measures the percentage of planned production time that is truly and fully productive. OEE Video Below.
Visual Factory emphasizes the role of visual communication, and more broadly the role of information sharing, in empowering and motivating employees, and aligning their efforts with the goals of the company. Visual Factory Video Below.
