The mass has a great influence on the value of products from different industries. For example, by reducing the mass of a product, the energy consumption and CO2 emissions can be reduced. These influences, which the mass has on different product properties, show why lightweight design is becoming increasingly important. Designers have to establish goals regarding mass in the early phases of the product development process, as otherwise the product may be too heavy after its design is completed. Nearly each function needs mass for its fulfillment but functions which are not important to the customer raise only the mass and not the customer value of the product. If designers had information about the importance of functions and the mass which is needed for their fulfillment, they would be able to discuss with their customer whether the functions are so important that they want to accept this extra mass in the product. Therefore, a method which supports designers in establishing goals regarding mass, and in analysing optimisation potentials, the importance of functions and the mass which is needed to fulfil the function based on the Value Analysis is operationalised in this paper.
