Which framework originated from automotive manufacturing and underpins LEAN practices?

• A. Toyota Production System (TPS)
• B. Lean
• C. Just-in-time (JIT)
• D. Keiretsu Relationships

Answer: (A)

The origin of Lean practices is the Toyota Production System, developed at Toyota after World War II to remove waste and improve flow in manufacturing. TPS introduced key ideas that Lean borrows, such as jidoka (building quality in and stopping problems at the source), continuous improvement (kaizen), and Just-in-Time production (which aims to produce only what is needed, when it is needed, and in the right amount). Why this is the best fit: Lean emerges from TPS as a broader philosophy and toolkit that captures the same goals—reducing waste, leveling production, and improving quality and speed. Just-in-Time is a component within TPS and Lean, but it is a specific practice rather than the complete framework itself. Keiretsu relationships describe interlinked corporate networks, not the method for organizing production and flow. So the Toyota Production System is the source that underpins Lean.
