This document discusses value analysis (VA), which is a systematic process for improving value through cost reduction and identification of unnecessary costs. It was developed in the US after World War II to analyze the functions of systems, materials, and processes. The VA process examines design, functions, and costs to identify ways to reduce costs without compromising quality or usefulness. It uses a 7-step approach including selection, analysis, innovation, evaluation, and implementation. VA focuses on understanding customer needs and eliminating unnecessary functions to improve value and profitability.
