• JIT - Pull parts through production based on customer demand instead of pushing parts through production based on projected demand. Relies on many lean tools, such as Continuous Flow, Heijunka, Kanban, Standardized Work and Takt Time.
• Kaizen (Continuous Improvement) - A strategy where employees work together proactively to achieve regular, incremental improvements in the manufacturing process.
• Muda (Waste) Reduction - Muda is anything in the manufacturing process that does not add value from the customer’s perspective.
• Jidoka - Design equipment to partially automate the manufacturing process (partial automation is typically much less expensive than full automation) and to automatically stop when defects are detected.
• Heijunka - A form of production scheduling that purposely manufactures in much smaller batches by sequencing (mixing) product variants within the same process.
• Poka Yoke - Error proofing. Design error detection and prevention into production processes with the goal of achieving zero defects. An example is different types of nozzles (that don't fit into the non-compatible vehicle) for diesel and petrol at gas stations. 
• Visual management - Visual indicators, displays and controls used throughout manufacturing plants to improve communication of information.
