In this paper we present the decision score, which is a model of decision-making seen in the engineering designer's perspective of the design process dynamics, where a decision has multiple objects and where it is based on earlier decisions, prediction of consequences and design process progression. The model is based on four observations: the engineering designers do not see a neat string of distinct and explicitly made decisions, there are several decision-makers during design, a design decision is not made at a distinct moment in time, and the decision object is evolving in time and changing in context. We have successfully made an attempt to justify the model by confronting it with several empirical studies of design decision-making.
