Implementing rationale crew system design through the Designer´s Electronic Notebook

The Boeing crew system design system is described. It consists of many separate components intended to provide direction and assistance to the crew system design effort. There are analytical software tools, databases to support design studies and decision-making, test and evaluation tools, and a documented design process. In order to obtain the maximum benefit from such a system, the designer is given guidance in the application of these resources. The Designer´s Electronic Notebook (DEN) has been developed to supply this assistance by guiding the designer through the design process, providing step-by-step design procedures, and directing the designer to the appropriate databases, tools, references, and resources. A description is given of the DEN and how it can aid the designer. Implementation factors, examples of its displays, and the benefits of using the DEN are presented.<>
