Value analysis (cost reduction for existing products) is especially worthwhile under which production context?
-
AHighly varied jobbing work with small quantities
-
BLarge-scale or mass production where savings repeat across many units
-
CSituations with only a few custom components
-
DOnly when very costly equipment is used, regardless of volume
-
EPrototype-only R&D with no repeat builds
Answer
Correct Answer: Large-scale or mass production where savings repeat across many units
Explanation
Introduction / Context:Value analysis reviews an existing design to maintain function while lowering cost. Its payoff depends on how often the savings recur, making production scale a key driver.
Given Data / Assumptions:
- Existing product with established function and performance.
- Feasible alternatives in materials, processes, or tolerances.
- Implementation costs can be amortised over production volume.
Concept / Approach:Because value analysis generates repeated per-unit savings, it is most attractive where unit volumes are high. Even small cost reductions yield large total savings when multiplied by thousands or millions of units.
Step-by-Step Solution:
Assess production context: jobbing vs. mass.Recognise that fixed effort of analysis is justified by recurring savings.Select large-scale production as the best scenario.Verification / Alternative check:Case studies from automotive and appliances consistently show large returns from value analysis because of high volumes.
Why Other Options Are Wrong:Jobbing/small runs: savings do not recur enough to offset effort.Few components or prototypes: benefits are limited by low repetition.Costly equipment alone does not guarantee payoff without volume.
Common Pitfalls:Ignoring tooling and qualification costs; overlooking life-cycle impacts (warranty/quality) when making substitutions.
Final Answer:
Large-scale or mass production where savings repeat across many units
