Which lean principle aims to remove waste from processes?

• A. Just-in-Time
• B. Kaizen
• C. Elimination of waste (Muda)
• D. Jidoka

Answer: (C)

The main idea being tested is removing activities that don’t add value to the customer. In lean thinking, waste (muda) is anything that consumes resources without contributing to what the customer actually wants. Focusing on eliminating waste means trimming processes so every step adds value and the flow is smoother. Elimination of waste is the explicit practice of identifying and removing those non-value-adding activities. While Just-in-Time aims to deliver goods exactly when needed and can reduce waste indirectly, the principle in question centers on removing waste itself. Kaizen emphasizes ongoing improvements across the process, which includes waste reduction but isn’t the sole focus. Jidoka involves building in quality and stopping the line to fix defects, which is a different lean mechanism.
