Details Processing in layout tackles the matter of making right details structures for designers. Given the ill-defined nature of layout difficulties, how do designers improve their wisdom base through the layout approach, what triggers their queries for info, what suggestions do they use, and what concerns effect their info looking habit? solutions to those questions are chanced on via a sequence of empirical studies--not simply theoretical solutions, but additionally a number of prototypes of verified software program instruments, that are defined intimately.

Actually, the fact that the designer is explicitly asked to write his initial interpretation of the problem makes him commit his ideas on paper. We have proposed before that sketching or writing down ideas on paper makes more likely becoming attached to them. This could actually be the reason why the final concepts of some designers were indeed the very first one they sketched. 6 General Discussion This chapter began by proposing that problem structuring or problem setting has three foundations: initial representation of the problem, the set of requirements and constraints (given or generated by the designer) and the information accessed.

They made extensive lists of what has to be transported when you move within and outside the office and in most cases, it was not until a lot of text had been written that they started sketching. This did not make a significant difference at the time of the evaluation of the results. Does spending much more effort and time on structuring the problem actually help improve the quality of the results? The answer we want to hear is yes, but the results show otherwise. This does not imply that trying to structure the problem is not useful at all, but it raises interesting questions as why this happens.

For example, three major concerns have been raised regarding protocol analysis. Protocols cannot capture everything, but only a part of the design process; thinking aloud might distort the design process and, in many cases, collecting protocols must be made in artificial settings. Regarding the first concern, Ericsson and Simon (1984) proposed that the accuracy of the verbalizations in a protocol is task specific. If the task involves only the use of short-term memory (like some puzzle-solving), the accuracy is high.
