Consistency management of product line requirements

摘要: Contemporary software engineering utilizes product lines for reducing time to market and development cost of a single variant, improving quality the products, creating better estimations process. Most line processes rely on performing domain analysis find out commonalities among proposed family members estimate how they will vary. On other hand, most requirements methods focus specification system. Despite active research efforts close this, gap there is still no effective method that allows specifications in arbitrary levels detail hierarchical family. In particular, it not possible combine different mechanisms produce complete specification. The authors approach these problems by presenting system both variant as well level. This exposes many managing consistency between specify families systems. To achieve our offers derivation management support variants.
