Value Engineering is a systematic method to improve the "Value" of goods and services by using an examination of function. Value, as defined, is the ratio of Function to Cost. Value can therefore be increased by either improving the Function or reducing the cost. It is a primary tenet of Value Engineering that quality not be reduced as a consequence of pursuing Value improvements.

In the United States, Value Engineering is specifically spelled out in Public Law 104-106, which states “Each executive agency shall establish and maintain cost-effective Value Engineering procedures and processes." [1]

Value Engineering is sometimes taught within the Project Management or industrial engineering body of knowledge as a technique in which the value of a system’s outputs is optimized by crafting a mix of performance (Function) and costs. In most cases this practice identifies and removes unnecessary expenditures, thereby increasing the value for the manufacturer and/or their customers. Project Management is the discipline of organizing and managing resources (i. ... This article needs additional references or sources to facilitate its verification. ... In mathematics, the term optimization, or mathematical programming, refers to the study of problems in which one seeks to minimize or maximize a real function by systematically choosing the values of real or integer variables from within an allowed set. ...

Value Engineering uses intuitive logic (a unique "how" - "why" questioning technique) and the analysis of Function to identify relationships that increase Value. It is considered a quantitative method similar to the Scientific Method, which focuses on Hypothesis - Conclusion to test relationships, and Operations Research, which uses model building to identify predictive relationships.

Value Engineering is also referred to as "Value Methodology".

The Origins of Value Engineering

Value engineering began at General Electric Co. during World War II. Because of the war, there were shortages of skilled labour, raw materials, and component parts. Lawrence Miles and Harry Erlicher at G.E. looked for acceptable substitutes. They noticed that these substitutions often reduced costs, improved the product, or both. What started out as an accident of necessity was turned into a systematic process. They called their technique “value analysis”. The General Electric Company, or GE, (NYSE: GE) is a multinational technology and services company. ...

As others adopted the technique, the name gradually changed to Value Engineering. VA / VE has been rehashed over the years into various other programs like lean, TQM, TRIZ, and business process reengineering. It has been suggested that this article or section be merged with Toyota Production System. ... ... TRIZ (pronounced [triz]) is a Russian acronym for Teoriya Resheniya Izobretatelskikh Zadatch (Теория решения изобретательских задач), a Theory of solving inventive problems or Theory of inventive problems solving (TIPS)(less known as Theory of Solving Inventors Problems), developed by Genrich Altshuller and his colleagues since 1946. ... Business Process Reengineering is a management approach aiming at improvements by means of elevating efficiency and effectiveness of the processes that exist within and across organizations. ...

The Job Plan

Value Engineering is often done by systematically following a multi-stage Job Plan. Larry Miles' original system was a six-step procedure which he called the Value Analysis Job Plan. Others have varied the Job Plan to fit their constraints. Depending on the application, there may be four, five, six, or more stages. One modern version has the following eight steps:

1. PREPARATION
2. INFORMATION
3. ANALYSIS
4. CREATION
5. EVALUATION
6. DEVELOPMENT
7. PRESENTATION
8. FOLLOW-UP

Four basic steps in the Job Plan are:

• Information gathering - This asks what the requirements are for the object. Function analysis, an important technique in value engineering, is usually done in this initial stage. It tries to determine what functions or performance characteristics are important. It asks questions like; What does the object do? What must it do? What should it do? What could it do? What must it not do?
• Alternative generation (Creation) - In this stage value engineers ask; What are the various alternative ways of meeting requirements? What else will perform the desired function?
• Evaluation - In this stage all the alternatives are assessed by evaluating how well they meet the required functions and how great will the cost savings be.
• Presentation - In the final stage, the best alternative will be chosen and presented to the client for final decision.

How it works

VE follows a structured thought process to evaluate options.

Gather information

1. What is being done now?

 Who is doing it? 

 What could it do? 

 What must not to do? 

Measure

2. How will the alternatives be measured?

 What are the alternate ways of meeting requirements? What else can perform the desired function? 

Analyze

3. What must be done?

What does it Cost?

Generate

4. What else will do the job?

Evaluate

5. Which Ideas are the best?

6. Develop and Expand Ideas What are the impacts? What is the cost? What is the performance?

7. Present Ideas Sell Alternatives
