Value analysis and value engineering are techniques used to analyze the value of products, processes, and capital projects. They involve identifying the functions of an item and finding ways to accomplish those functions at the lowest total cost while maintaining quality and performance. Value analysis was traditionally used on existing products while value engineering focused on new products at the design stage. Both aim to reduce unnecessary costs and improve operations and product performance using techniques like function analysis. The concepts and techniques were developed in the 1940s at GE by Lawrence Miles, who is considered the father of value analysis and value engineering.
