In lean enterprise, which type of waste specifically refers to unnecessary movement of workers within a work area?
Answer: Motion
Motion waste refers to unnecessary physical movements of workers (reaching, bending, walking) that do not add value to the product.
A lean enterprise team applies 'heijunka' to their production schedule. What does heijunka primarily accomplish?
Answer: Levels production volume and mix over time
Heijunka levels production by smoothing out volume and product mix variations, preventing overburden and uneven workloads.
Which lean principle emphasizes going to the actual place where work is done to observe and understand the current state?
Answer: Gemba
Gemba (Japanese for 'the real place') is the practice of going to where value is created to directly observe processes and identify waste.
In the context of lean enterprise, 'muri' refers to which category of operational problem?
Answer: Overburden
Muri refers to overburden — unreasonable stress placed on workers or machines that leads to breakdowns, errors, and safety issues.
A lean Black Belt wants to reduce changeover time between product variants. Which technique is specifically designed for this purpose?
Answer: SMED
Single-Minute Exchange of Die (SMED) is a lean technique that reduces changeover time to less than 10 minutes by converting internal to external setup tasks.
In a lean value stream map, a 'push' arrow indicates that material is being:
Answer: Moved based on a schedule or forecast regardless of downstream need
A push arrow shows that material is moved or produced based on a schedule or forecast, not on actual downstream demand signals.
Which lean enterprise concept directly supports the idea that quality should be built into the process rather than inspected in at the end?
Answer: Jidoka
Jidoka builds quality into the process by stopping production when defects occur, preventing defective products from advancing downstream.
