To look on this means at technological design as a decision-making process is to view it normatively from the perspective of sensible or instrumental rationality. At the same time it is descriptive in that it is a description of how engineering methodology typically presents the difficulty the way to clear up design problems. The fourth category issues the quantitative data just referred to, and the third the theoretical instruments used to acquire it. These two classes can be assumed to match Bunge’s notion of substantive technological theories.
