Value engineering is a technique that uses a set of skills and methods to identify unnecessary costs in a systematic way. It aims to improve value through cost reduction without sacrificing quality, usefulness, or customer satisfaction. The value engineering process involves gathering information, functional analysis, developing alternatives through creative techniques, evaluation using tools like decision trees and matrices, and implementation. A case study demonstrates using ANP software to evaluate alternatives for establishing a cost control department, identifying creation as an independent department as the preferred option.
