Question 2

Which waste category in the Toyota Production System refers to excess inventory beyond immediate production needs?

Accepted Answer

Inventory waste

Answer

Inventory waste (one of the seven muda) specifically covers any stock beyond the minimum needed to keep production flowing.

Question 3

A lean team conducts a 'gemba walk.' What is the primary purpose of this activity?

Accepted Answer

Going to the actual workplace to observe real processes and identify waste

Answer

Gemba walks involve direct observation at the point of work to see waste and inefficiencies that data reports often miss.

Question 4

In lean inventory thinking, which condition justifies holding safety stock?

Accepted Answer

Demand variability or supply uncertainty that cannot yet be eliminated

Answer

Safety stock is a temporary buffer for variability; lean aims to reduce variability so safety stock can eventually be minimized.

Question 5

What is the main difference between 'push' and 'pull' production systems?

Accepted Answer

Push systems produce based on forecasts; pull systems produce only in response to actual demand

Answer

Pull systems replenish only what has been consumed, eliminating the forecast-driven overproduction that generates excess inventory.
