Supporting requirement engineering in complex product design
Résumé
Requirement engineering and management has become a complex task in concurrent engineering context. Due to the co-evolutionary design process nature requirements have to be taken into account by all designers as soon as possible and have to dynamically change throughout the design process. The F-Requirement Relation network (FRRN) is proposed as the core element to support the design process. The idea was tested on a complex product design in a French large company. It can be concluded that building such a network can be achieved practically but organisational conditions have to be managed to make it more efficient: the first one is related to the project and its organisation in expertise groups that fix responsibilities; the second one is related to the product, which complexity is pragmatically split into sub-projects that are more expert oriented than project oriented.
