Product Management Production Management 5

Question 1

In a Value Stream Map (VSM), 'push' arrows between process steps indicate:

Accepted Answer

Material is pushed forward regardless of downstream readiness

Answer

Push arrows in VSM show material being moved forward based on schedules, not downstream pull signals.

Question 2

A manufacturer's process yield is 95% at each of four sequential steps. What is the rolled throughput yield (RTY)?

Accepted Answer

81.45%

Answer

RTY = 0.95 × 0.95 × 0.95 × 0.95 ≈ 81.45%, showing cumulative defect probability across all steps.

Question 3

Which approach to production capacity management deliberately maintains excess capacity to absorb demand spikes without delays?

Accepted Answer

Lead strategy

Answer

A lead strategy builds capacity ahead of demand to ensure availability, accepting the cost of temporary idle capacity.

Question 4

Poka-yoke devices are used in production to:

Accepted Answer

Prevent defects by making errors impossible or immediately obvious

Answer

Poka-yoke (mistake-proofing) designs physical or procedural mechanisms that make human errors impossible or instantly detectable.

Question 5

When a product manager conducts a 'capacity cushion' analysis, they are evaluating:

Accepted Answer

The buffer between actual demand and maximum production capacity

Answer

A capacity cushion is the amount of capacity reserved above expected demand to handle variability and avoid overload.
