Abstract
This paper discusses Hyper Design which is a new design paradigm and shows its method- ology concretely. A scientific design is carried out using the expression, however, it is approximate expression. The approximate expression is often a multivariate multinomial expression made by the data which is acquired by an experiment plan. When the specific variable (hyper factor) is focused in this expression, another multinomial expression based on focused variable can be constituted. After it is constituted, the necessary role is assigned for focused variable, design is enabled. An engineer has the freedom to decide which variable must be focused and decide which role must be assigned for it. This paper discusses a design as free creative activity of engineer from this point of view. Hyper Design discussed in this paper is capable to explain various types of design in a comprehensive manner, and at the same time, it is applicable to wide area of actual practices.
