Feature unweaving: efficient variability extraction and specification for emerging software product lines


Stoiber, R; Glinz, M (2010). Feature unweaving: efficient variability extraction and specification for emerging software product lines. In: 4th International Workshop on Software Product Management (IWSPM'10), Sydney, Australia, 27 September 2010 - 27 September 2010.

Abstract

Successful software products frequently evolve into software product lines, whether intentionally or not. In such cases, product managers have to be involved in creating and specifying the commonality and variability of the evolving software product line in order to continuously assure a winning business case. In this paper we introduce feature unweaving, a novel approach that allows a product manager to efficiently evolve an integrated graphical requirements model into a product line model: when he or she has identified variable elements, feature unweaving automatically extracts these elements and refactors them into a feature, using an aspect-oriented approach. Feature unweaving significantly reduces the required effort for variability specification, both on a clerical and intellectual level. Furthermore, variability constraints can be added to capture more knowledge about the features and their interdependencies. We evaluate and validate our approach with two case studies.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
