MODELING - THE LANGUAGE OF THE DESIGNER

Modelling is the language by which the designer or product developer can elaborate, synthesize, evaluate and communicate. There exists a number of model types, supplementing each other and, all together, supporting the design procedure from initial recognition of a market need through until the product is sold. In European design methodlogy, the central problem has been to determine the set of design characteristies able to describe the design progress and to create models able to handle these characteristics. These models and their concepts may be seen as a design language. By accepting such a language developed by a design school and by using the design methodlogy, the designer can tell us about the usability of this school and the 'truth' of the theories. This article aims to show the role of modelling in design and the many open questions needed to be answered (by design science) in order to develop better tools. The article is rather an essay with personal, calaidoscopic consideration focused on the so called Workshop Design-Konstruktion school and the contributions of V. Hubka, than a scientific contribution.
