What is VAVE?

Value Analysis and Value Engineering (VAVE) is a powerful, systematic methodology used to analyze and improve the value of products, projects, or services. "Value" is defined by the ratio of function to cost. The goal is to achieve the required functions at the lowest possible lifecycle cost without compromising quality, reliability, or customer satisfaction.

The core principle is expressed in the value equation: Value = Function / Cost

  • Value Analysis (VA): Typically applied to existing products to reduce their cost or improve their function. It's a reactive approach to enhance value.
  • Value Engineering (VE): Applied during the design and development phase of a new product. It's a proactive approach to build value in from the start.

VAVE combines both approaches into a unified process for continuous value improvement.

Instructions

For each function identified in your system, assign:

  • Cost ($): The estimated cost associated with this function
  • Value Score (1-10): How important this function is to the customer/system (1=least, 10=most)
  • Value Index = Value Score / Cost (Higher is better)

Functions with low value index are candidates for cost reduction or functional improvement.
