Value analysis is a method to increase the value of a product, system, process or service by improving its functions while reducing costs. It evaluates a product's utility, esteem and market values. Utility value is how useful the product is, esteem value is attributes not related to function but aesthetic, and market value is what customers will pay. Value is improved by reducing component costs, modifying unnecessary secondary functions, focusing on essential functions, and getting team consensus. Value analysis is needed to assess customer needs, obtain feedback, plan better products, and reduce costs and waste while improving profits, customer satisfaction, and employee morale.
