Techniques Of Value Analysis And Engineering

Value engineering VE is a systematic method to improve the "value" of goods or products and services by using an examination of function. Value, as defined, is the ratio of function to cost. Value can therefore be manipulated by either improving the function or reducing the cost. It is a primary tenet of value engineering that basic functions be preserved and not be reduced as a consequence of pursuing value improvements.

The reasoning behind value engineering is as follows: if marketers expect a product to become practically or stylistically obsolete within a specific length of time, they can design it to only last for that specific lifetime. The products could be built with higher-grade components, but with value engineering they are not because this would impose an unnecessary cost on the manufacturer, and to a limited extent also an increased cost on the purchaser.

Value engineering will reduce these costs. A company will typically use the least expensive components that satisfy the product's lifetime projections. Due to the very short life spans, however, which is often a result of this "value engineering technique", planned obsolescence has become associated with product deterioration and inferior quality.

Vance Packard once claimed this practice gave engineering as a whole a bad name, as it directed creative engineering energies toward short-term market ends. Philosophers such as Herbert Marcuse and Jacque Fresco have also criticized the economic and societal implications of this model. Value engineering began at General Electric Co. Because of the war, there were shortages of skilled labour, raw materials, and component parts.

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". It is based on an analysis investigating systems, equipment, facilities, services, and supplies for providing necessary functions at the lowest life cycle cost while meeting the required targets in performance, reliability, quality, and safety.

VE follows a structured thought process that is based exclusively on "function", i. For example a screw driver that is being used to stir a can of paint has a "function" of mixing the contents of a paint can and not the original connotation of securing a screw into a screw-hole. In value engineering "functions" are always described in a two word abridgment consisting of an active verb and measurable noun what is being done — the verb — and what it is being done to — the noun and to do so in the most non-prescriptive way possible.

In the screw driver and can of paint example, the most basic function would be "blend liquid" which is less prescriptive than "stir paint" which can be seen to limit the action by stirring and to limit the application only considers paint.

This is the basis of what value engineering refers to as "function analysis". Value engineering uses rational 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 approaches to test relationships, and operations research, which uses model building to identify predictive relationships.

Value Analysis

Value Analysis VA is a systematic method to improve the "value" of goods or products and services by using an examination of function. Value, as defined, is the ratio of function to cost. Improving the function or reducing the cost can therefore increase value. VA follows a structured thought process that is based exclusively on "function", i. For example a screwdriver is used to pry open a can of paint has a "function" of opening the container of a paint, and not the original connotation of securing a screw into a screw-hole. In value analysis "functions" are always described in a two-word combination consisting of an active verb and measurable noun.

Techniques of Value Analysis and Engineering by Lawrence D Miles

Concerned with the application of a product cost reduction technique known as Value Analysis VA. Demonstrates that well established companies like Chubb are realizing the importance of VA to increasing their product focus and the benefits achievable through the use of this technique. Centres upon the application of VA: why the technique was seen as appropriate to the needs of Chubb and what comprises VA; the process of establishing the team within Chubb to undertake the VA exercise; the work carried out by the members of the team and their achievements. Gives an overview and lessons learned from the exercise.
