Errors in architectural design process : towards a cognitive model.

In architectural design process, the human error has a particular status. The later it is detected, the more expensive it is. Moreover, some errors can not be detected given the current state of the design process and object definition. In this paper, we propose a model based on cognitive theories about human errors, applied to architectural preliminary design. In this model we classify the consequences of a design decision (direct, indirect, detected and undetected), we describe the steps of decision in architecture in relation to the process of errors detection and we introduce the concept of evolutive context.
