In a Value Stream Map (VSM), 'push' arrows between process steps indicate:
Answer: Material is pushed forward regardless of downstream readiness
Push arrows in VSM show material being moved forward based on schedules, not downstream pull signals.
A manufacturer's process yield is 95% at each of four sequential steps. What is the rolled throughput yield (RTY)?
Answer: 81.45%
RTY = 0.95 × 0.95 × 0.95 × 0.95 ≈ 81.45%, showing cumulative defect probability across all steps.
Which approach to production capacity management deliberately maintains excess capacity to absorb demand spikes without delays?
Answer: Lead strategy
A lead strategy builds capacity ahead of demand to ensure availability, accepting the cost of temporary idle capacity.
Poka-yoke devices are used in production to:
Answer: Prevent defects by making errors impossible or immediately obvious
Poka-yoke (mistake-proofing) designs physical or procedural mechanisms that make human errors impossible or instantly detectable.
When a product manager conducts a 'capacity cushion' analysis, they are evaluating:
Answer: The buffer between actual demand and maximum production capacity
A capacity cushion is the amount of capacity reserved above expected demand to handle variability and avoid overload.
In Material Requirements Planning (MRP), 'gross requirements' are converted to 'net requirements' by:
Answer: Subtracting on-hand inventory and scheduled receipts
Net requirements = Gross requirements − On-hand inventory − Scheduled receipts, revealing the true quantity that must be ordered.
A plant manager wants to improve flow efficiency and eliminate non-value-added waiting between departments. Which lean tool best maps and quantifies this waste?
Answer: Value Stream Mapping (VSM)
VSM visualizes the entire production flow, clearly distinguishing value-added from non-value-added time and identifying waste.
