Qisqacha
This short paper reviews how established design process models write design specifications. It argues that Quality Function Deployment (QFD), the method most of them rely on, is poorly suited to new, innovative products. It names three challenges and presents itself as the first step toward a new user-centered design specification method.
Muammo va dolzarblik
A design specification is a document listing the requirements a product must meet. User-centered product development aims to involve users and study their needs in depth to set these requirements, yet not every new product meets users' demands. The paper aims to analyze existing problems with design specification methods in new product development.
Usul va yondashuv
A literature-based review. The paper compares four design process models (Ulrich and Eppinger; Ullman; Pahl and Beitz; Pugh) in a table by specification method, example product, field and the terms they use for the specification. It then explains Quality Function Deployment (QFD), a widely used method that converts customer or user needs into design requirements using a relationship matrix and prioritizes them through competitive product analysis, and lists Ullman's eight QFD steps.
Asosiy natijalar
- Review finding: although the models use different names (product specifications, engineering specifications, requirement list, product design specification), they specify requirements in almost the same way because they rely on QFD; Pugh's model uses an enhanced QFD.
- Conceptual challenge 1: QFD focuses on incremental improvements to existing products, and its competitive analysis needs comparable products, which do not exist for a genuinely new product.
- Conceptual challenge 2: user involvement is limited. QFD is described as a "design for" approach in which users take part only in the initial phase, whereas user-centered development calls for a "design by" approach with active user participation.
- Conceptual challenge 3: current models are oriented toward engineering design rather than industrial design, with engineering designers as the leading actors in specification.
- Review finding: models that support user participation, such as user-oriented product development and customer idealized design, are rarely used in practice to turn user needs into design requirements.
Hissa va xulosalar
The authors conclude that a design specification method is needed that can be applied to innovative product design and that involves users throughout product development. They present this paper as the first step toward developing such a method. Planned further research includes developing the new user-centered design specification method, case studies of its practical application, and an assessment of its pros and cons in practice. The paper does not state limitations.
