Towards a Model-Based Framework for Linking Design Requirements to the Functional Layout of the Product

Abstract

Abstract The aim of this paper is to bridge the gap between the requirements and the functional layout of a product during the early phases of product development. During these early phases, it is important to capture the customer’s desires in order to achieve success in the market. A common methodology for this is Quality Function Deployment (QFD). However, we argue that it is important to consider different stakeholder needs and not only the ‘voice of the customer’ to create a well-balanced product. The proposed model uses a QFD with a broader approach in which different stakeholders are considered. The needs from the stakeholders are divided into functional requirements and non-functional requirements (constraints), and linked to the functional layout. The model will support the decision-making process and help the designer balance the interests of different stakeholders and the related functions, resulting in a more balanced product. The model has been applied in an industrial case study.
