The Component Market as New Force in Requirements Engineering – CRRE as Approach: Evaluation of a Requirements Engineering Approach for Adaptive Component–based Systems

Component–based software engineering uses already existing building blocks of software (components) to develop new individual software. But sometimes it happens that one or many of these used components have a malfunction. Software which can handle this is called adaptive component–based software. The presented CRRE (Circuit Response driven Requirements Engineering) process is based on SeCSE ESD (Service Centric System Engineering – Early Service Discovery). I used the ESD process and enrich it among others with a definition of software borders. This should specify the customer needs for the later software in a very coarse–grained way. I have also simplified some steps in the process to make it more comprehensible for the customer.Last I have enriched it with my Feature Modification Model. This model offers the possibility to define the software features in ranges, so that a candidate set of components can be found based on these features. So it is possible to find more components which probably fulfil the consumer needs.As an initial evaluation I also present a word processor as a case study with interesting results presented in this publication.
