Value Engineering and Value
Analysis
Overview
• What is Value Engineering?
• How is VE Applied?
• When is it used?
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.

The Key Points of VA / VE
• Applying formal work plans.
• A team approach.
• Specific definition of functions.
• The simultaneous look at functions and costs.
• Control of the analysis process.
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

Value Engineering is used to determine the bestdesign alternatives for Projects, Processes,
Products, or Services

Value Engineering is used to reduce cost on existing Projects, Processes, Products, or Services.•
Value Engineering is used to improve quality,increase reliability and availability, and customer satisfaction .
•
Value Engineering is also used to improveorganizational performance.
•
Value Engineering is a powerful tool used to identifyproblems and develop recommended solutions.
Benefits of VE
• Decreasing costs
• Increasing profits
• Improving quality
• Expanding market share
• Saving time
• Solving problems
VE’s Weaknesses
Successful VE results are dependent on the quality of information brought to the VE workshop for
evaluation.
VE is not time oriented, but, product oriented. Thus, improvements in production activities are not readily recognized.
There are many misunderstandings and biases
against VE that have been built up over time due to misuse of the methodology.
“It cheapens the product without improving it.” “VE is only used for cost reduction.”
Value Engineering Research
Questions and Check Sheet
1. Can it be eliminated without impairing
function or reliability?
2. Does it cost more than its worth?
3. Does it do more than is required? Are there
unnecessary features?
4. Is there something better with which to do
the job?
Value Engineering Research
Questions and Check Sheet
5.Can it be made by a less costly method?
6. Can a standard item or specialty product be
used?
7. Could a less costly manufacturing technique
be used?
8. Should different tooling be used?
9.Can someone else provide it at less cost
without affecting dependability?

What is value?
VALUE = What we get out of something What we put into it
VALUE = Quality, reliability, appeal, etc = Benefits Cost, time, mass, energy, etc. Resources
VALUE = Worth = Performance Cost Cost
Delivery of necessary project functions while achieving best balance between project performance and project costs.

gather information on the background, functions and requirements of the product, process, or system.
Brainstorm ideas on how to improve the high cost,
broken, or inadequately performed key functions.
Screen ideas for acceptance, score remaining ideas
on a scale and group ideas into categories. Develop design scenarios, and selection criteria. Rate and rank ideas.
Plan how to sell ideas to management, identify key
recommendations, plan management presentation.
Give oral presentation to management, or develop
written report.
Get management approval for go-ahead, make

Information Phase-Fact Finding
What do you need to know about the problemthat you don’t know now?
What facts are known?
What are the requirements of thesystem?
Are these facts, opinions,assumptions, or prejudices?
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

Creativity Techniques- Brainstorming
Generate a large number of ideas - quantity, not quality.
Free-wheeling is encouraged - Listen and improve on the ideas of others.
Don’t criticize - No evaluation of ideas
Encourage everyone to participate
Record all ideas presented
Time to let ideas “incubate” should be allowed.
Function Analysis
Function Analysis is the key to
understanding the problem.
Brainstorm all possible functions
Next, build a FAST Model to help
identify any missing functions.

ACTION PLAN GUIDELINES
“What needs to be done?”
Identify the actions needed to “solidify” the
proposals.
“Who should be assigned the action?”
Assign a team member.
Assign a completion date for the action.
“When should the task be completed?”
Plan regular team status meetings.
Implementation Planning
Ideas must be planned and managed to ensure
implementation.
Proposed actions should be managed like a
project with specific end products, defined start and end dates, and funding limits.
The Planning & Reporting Phase
•
Reporting
Give oral presentation.
Support it with written executive brief.
Be clear, concise, and positive.
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
The Value Engineering Checklist
1. Can the item be eliminated?
2. If the item is not standard, can a standard item be used?
3. If it is a standard item, does it completely fit the application, or is it a misfit?
4. Does the item have greater capacity than required?
5. Can the weight be reduced?
6. Is there a similar item in inventory that could be substituted?
7. Are closer tolerances specified than are necessary?
The Value Engineering Checklist
8. Can you make the item less expensively in your plant? If you are making it now, can you buy it for less?
9. Can cost of packaging be reduced?
10. Are suppliers contributing suggestions to reduce cost?
