This paper defends an augmented cognitively oriented "generic-design
hypothesis": There are both significant similarities between the design
activities implemented in different situations and crucial differences between
these and other cognitive activities; yet, characteristics of a design
situation (i.e., related to the designers, the artefact, and other task
variables influencing these two) introduce specificities in the corresponding
design activities and cognitive structures that are used. We thus combine the
generic-design hypothesis with that of different "forms" of designing. In this
paper, outlining a number of directions that need further elaboration, we
propose a series of candidate dimensions underlying such forms of design
