Definitions
Value Engineering is a technique applied to identifying optimum value solutions during new product development.
Value analysis is a technique applied to improving existing products, processes or services. The objective is usually to reduce cost, but may equally or simultaneously be to improve performance or quality.

What is VALUE
Value is the relationship between the defined function the customer requires and the costs incurred to provide that function.
Cost Value
Use Value
Esteem Value
Exchange Value
When is VE used
Existing part/product cost is high
Existing technology is complex/old though simpler means are available
There is a need to release a cheaper product by cutting down some of the existing feature
The existing customer demands a minimal increment in product features that are in use
There is a need to cut down the manufacturing cycle time/cost
Function Analysis
Shifts the problem-solving focus away from the items toward the functions
Function need be defined by two words: an Active Verb and a Measurable Noun
The verb defines the required action; the noun tells what is being acted on
The more abstract the function definition, the greater the opportunities for finding creative alternatives
Analysis of Each Component
Can any part be eliminated without impairing the operation of the complete unit?
Can the design of the part be simplified to reduce its basic cost?
Can the design of the part be changed to permit the use of simplified or less costly production methods?
Can less expensive but equally satisfactory materials be used in the part?
Design simplifications frequently are more apparent than is possible under the original design
Concluding Remarks
The design stage provides the greatest opportunity to reduce costs
