Nützliche Anforderungstraceability in Richtung des Designs ist schwer erreichbar, da zwischen Problem und Lösung eine Vielzahl getroffener Entscheidungen steht. Der vorliegende Artikel skizziert kurz unser zentrales Konzept zur Integration von Entscheidungen in die Traceabilityinformation. Wir schlagen dafür einen leichtgewichtigen skalierbaren Ansatz vor,(More)
Requirement traceability ensures that (SW-)products meet their requirements and additionally makes the estimation of the consequences of requirement changes possible. It is especially difficult to establish at the transition from requirements specification to its provision in the design, because design processes represent creative and complex transfers of(More)
Requirements and requirement traceability play a key role in ensuring that embedded systems meet their goals. This article deals with improving requirements and requirement traceability to design artifacts in the context of embedded design. We identify a way for capturing decisions concerning limited resources in embedded systems. This approach directly(More)
Requirement traceability ensures that software products meet their requirements and additionally makes the estimation of the consequences of requirement changes possible. In this article a case study analyses symptoms of this problem in the process model of ISO 12207, the foundation of SPICE (ISO 15504), and CMMi. Our analysis is directed at deriving a(More)
