Consistency management of product line requirements

摘要

Contemporary software engineering utilizes product lines forreducing time to market and development cost of a single productvariant, for improving quality of the products, and for creating betterestimations of the development process. Most product line developmentprocesses rely on performing a domain analysis to find out commonalitiesamong proposed family members and to estimate how they will vary. On theother hand, most requirements engineering methods focus on thespecification of a single system. Despite active research efforts toclose this, gap there is still no effective method that allows productspecifications in arbitrary levels of detail for a hierarchical productfamily. In particular, it is not possible to combine differentspecification mechanisms to produce a complete family specification. Theauthors approach these problems by presenting a method that allowssystem specifications both in the product line variant as well as theproduct family level. This exposes many problems in managing consistencybetween different methods to specify families of systems. To achievethis, our method offers derivation of consistency management supportbetween different specification levels and among family variants
