Question 1: A manufacturing team notices that operators frequently walk long distances between workstations. Which type of waste does this represent?
- Motion (Correct answer)
- Transportation
- Waiting
- Overprocessing
Correct answer: Motion
Unnecessary operator movement between workstations is classified as motion waste in Lean terminology.
Question 2: What is the primary purpose of a Value Stream Map (VSM) in Lean methodology?
- To visualize the flow of materials and information and identify waste (Correct answer)
- To assign blame for process inefficiencies
- To calculate financial ROI of improvement projects
- To schedule employee shifts
Correct answer: To visualize the flow of materials and information and identify waste
A Value Stream Map visualizes the entire flow of materials and information to help teams identify and eliminate waste.
Question 3: Which Lean principle states that production should be driven by actual customer demand rather than forecasts?
- Pull (Correct answer)
- Flow
- Perfection
- Value
Correct answer: Pull
The pull principle ensures production is triggered by actual customer demand, reducing overproduction waste.
Question 4: A company produces 500 units per day but customers only order 300. Which waste is most directly created?
- Overproduction (Correct answer)
- Inventory
- Defects
- Overprocessing
Correct answer: Overproduction
Producing more than customer demand constitutes overproduction, which Lean considers the most critical waste.
Question 5: In Lean thinking, which activity would be classified as 'necessary but non-value-added'?
- Regulatory compliance inspections (Correct answer)
- Reworking defective parts
- Storing finished goods in a warehouse
- Moving materials between buildings
Correct answer: Regulatory compliance inspections
Regulatory inspections do not add value from the customer's perspective but are legally required and cannot be eliminated.

- Unevenness or irregularity in workload (Correct answer)
- Overburdening of people or equipment
- Wasteful activities
- Continuous improvement
Correct answer: Unevenness or irregularity in workload
Mura refers to unevenness or inconsistency in production schedules and workloads, which creates waste downstream.
