Value analysis

Value analysis is a historical tool that was once used as the basis for identifying components to trim. At the time, this term referred to the simultaneous execution of function modeling and cost analysis.

Value analysis involved calculating and comparing value of system components. It was conducted based on the function-cost diagram.

Today, it is rarely used in projects and has been replaced by other tools. Practice has shown that the list of components immediately associated with key disadvantages from CECA or the disadvantages (mainly cost-related) identified through function-cost analysis provide much more reliable indications than the value of components derived from calculations.
