有人建议，有重要的概括，在设计活动中，跨越特定学科的问题解决。本文提出了一个设计研究的框架：（a）将设计描述为一个辐射范畴，并充实了原型案例的任务环境;（B）认真对待任务环境;（c）表明这种任务环境出现在设计任务中，但并不出现在每一个非设计任务中;（d）阐明这种任务环境对设计问题空间的影响;以及（e）证明，给定信息处理系统的结构，在设计任务的问题空间中注意到的特征将不会全部出现在任务环境大不相同的问题空间中。这种分析导致的索赔，有一组不变的功能，共同构成一个设计问题空间的设计情况的问题空间。协议的研究报告，其中三个设计任务的问题空间，在建筑，机械工程，教学设计进行了探索和比较，从非设计解决问题的任务的几个协议。
It is proposed that there are important generalizations about problem solving in design activity that reach across specific disciplines. A framework for the study of design is presented that (a) characterizes design as a radial category and fleshes out the task environment of the prototypical cases; (b) takes the task environment seriously; (c) shows that this task environment occurs in design tasks, but does not occur in every nondesign task; (d) explicates the impact of this task environment on the design problem space; and (e) demonstrates that, given the structure of the information-processing system, the features noted in the problem spaces of design tasks will not all occur in problem spaces where the task environment is vastly different. This analysis leads to the claim that there are a set of invariant features in the problem spaces of design situations that collectively constitute a design problem space. Protocol studies are reported in which the problem spaces of three design tasks in architecture, mechanical engineering, and instructional design are explored and compared with several protocols from nondesign problem-solving tasks.
