Q

N10. What is value engineering?

A

Maximising value, through eliminating unwanted costs whilst improving functionality.

Increasing the margin between value/revenue and cost

Value engineering is not simply cost cutting, it can in fact lead to an increase in cost sometimes.

To succeed in VE, increases in value must be achieved with a lower cost impact. Similarly, decreases in value must be met with a greater reduction in cost/.
