Component Market as New Force in Requirements Engineering - CRRE as Approach

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.
