Which framework is the basis for LEAN?

Which framework is the basis for LEAN?

• A. Toyota Production System (TPS)
• B. LEAN
• C. Efficient Consumer Response (ECR)
• D. Quick Response

Answer: (A)

Lean traces its roots to the Toyota Production System. Toyota developed a comprehensive way of manufacturing that centers on eliminating waste, smoothing production, and empowering workers to stop problems and improve processes. Key elements from TPS—just-in-time flow, jidoka (automation with a human touch to stop defects), heijunka (production leveling), kanban signaling, standardized work, and continuous improvement (kaizen)—were distilled into the Lean approach. Over time, scholars and practitioners abstracted those TPS practices into a broader philosophy labeled Lean, applicable beyond manufacturing to many processes. The other options describe different supply-chain ideas or programs that aim to improve speed or collaboration but did not establish the foundational framework for Lean.
