Abstract. This paper introduces conceptual designing within an F-B-S framework. It then goes on to describe a number of models of designing before introducing the notions of situatedness and situated acts. The remainder of the paper describes the role of situatedness and situated acts in conceptual designing. It attempts to show that a number of otherwise difficult design phenomena are modelable using situatedness and situated acts. A demonstration example concludes the paper along with some of the research issues this view of designing brings with it.
