  • VA (Value Analysis) is a concept developed by the GE Company in 1947. VA provides a method to increase the value of a product or service, specifically by analyzing various factors associated with the value relative to the minimum resources necessary to produce said product or service (its cost). TDK uses the terms VE (Value Engineering) and VA synonymously.
