A lean enterprise conducts a 'kaizen event.' What is the primary characteristic that distinguishes a kaizen event from regular improvement activities?
Answer: It is a rapid, focused improvement effort typically lasting 3-5 days
A kaizen event (or rapid improvement event) is an intensive, cross-functional workshop lasting typically 3-5 days that implements improvements immediately.
In lean thinking, which of the following is considered an example of 'overprocessing' waste?
Answer: Applying tighter tolerances than the customer requires
Overprocessing waste occurs when more work, precision, or features are added to a product than the customer values or requires.
Hoshin kanri (policy deployment) in a lean enterprise is best described as:
Answer: A strategic planning process that aligns organizational goals with daily operational activities
Hoshin kanri is a strategic planning methodology that cascades organizational goals through all levels, ensuring daily actions align with long-term objectives.
Which lean metric directly measures the percentage of time a process produces good parts relative to planned production time?
Answer: Overall Equipment Effectiveness (OEE)
OEE combines Availability, Performance, and Quality rates to measure how effectively manufacturing equipment is being used relative to its full potential.
In a lean enterprise, 'standard work' primarily serves which function?
Answer: Documents the current best-known method to ensure consistent, repeatable performance
Standard work documents the safest, highest-quality, most efficient method currently known, providing a stable baseline for continuous improvement.
A lean Black Belt is evaluating a process where workers must walk 50 feet to retrieve tools stored in a central cabinet. This is an example of which type of waste?
Answer: Motion
Walking to retrieve tools is motion waste — unnecessary physical movement by workers that does not add value to the product.
The lean concept of 'supermarket' in a pull system refers to:
Answer: A controlled inventory buffer between processes that replenishes based on consumption
A supermarket is a strategically sized inventory buffer where a fixed quantity of parts is stored and replenished only when consumed by the downstream process.
