1. In Lean Manufacturing, what is the primary objective of 5S
methodology?
A. To increase inventory levels
B. To create a workplace that is orderly and efficient
C. To extend process cycle times
D. To maximize product variation
The 5S methodology is intended to organize and standardize the
workplace, reducing waste and inefficiencies.
2. Which form of waste in Lean is represented by producing more than
what is needed?
A. Waiting
B. Transportation
C. Overproduction
D. Defects
Overproduction waste occurs when goods are made in excess of demand,
leading to inventory accumulation.
, 3. What does the Lean tool Kaizen emphasize?
A. One-time large changes
B. Maximizing inventory
C. Eliminating standard work
D. Continuous incremental improvement
Kaizen focuses on ongoing small improvements that cumulatively enhance
process performance.
4. The term “Muda” in Lean refers to:
A. Standardized work
B. Any activity that does not add value
C. Customer lead time
D. Total productive maintenance
Muda is the Japanese term for waste, defined as any non-value-adding
activity.
5. In Lean, Value Stream Mapping is used to:
A. Increase setup times
B. Visualize and analyze the flow of materials and information
C. Replace process documentation
D. Expand product variants
Value Stream Mapping helps chart current and future state flows to
identify improvement opportunities.
6. Which of the following best describes Takt Time?
A. Machine downtime
B. Total cycle time
C. Batch size
D. The rate at which a product must be completed to meet customer
demand
, Takt Time aligns production pace with customer demand to avoid
overproduction.
7. A Pull System in Lean means:
A. Producing in anticipation of demand
B. Using push notifications
C. Producing only what the customer has ordered
D. Stockpiling finished goods
Pull systems limit production until there is demand, reducing inventory
waste.
8. Standard Work documentation is essential because it:
A. Eliminates variation entirely
B. Encourages workers to change procedures frequently
C. Establishes the best-known method for performing a task
consistently
D. Reduces takt time to zero
Standard Work defines the most efficient and consistent method to
perform tasks, ensuring quality and repeatability.
9. The Lean concept of Poka-Yoke is intended to:
A. Increase batch size
B. Prevent errors from occurring
C. Speed up transportation
D. Standardize scheduling
Poka-Yoke devices help avoid mistakes by designing processes so errors are
impossible or immediately detectable.
10. Which Lean metric calculates the percentage of value-added
time versus total lead time?
A. Run rate
B. Scrap rate
