Question 3
Which of the following is TRUE concerning value-engineering?
Question 3 options:
1-After a product's design has been value-engineered, costs are
difficult to influence.
2-Value-engineering activities reduce both value-added and
non-value-added costs.
3-The goal of value-engineering is to eliminate locked-in
costs.
4-When and how costs are locked in are more important than when
and how costs are incurred.
5-Value-engineering does not work when dealing with direct
costs.
