Reusability assessment is vital for software product line due to reusable nature of its core components. Reusability being a high level quality attribute is more relevant to the software product lines as the entire set of individual products depend on the software product line core assets. Recent research proposes the use of aspect oriented techniques for product line development to provide better separation of concerns, treatment of crosscutting concerns and variability management. There are quality models available which relate the software reusability to its attributes. These models are intended to assess the reusability of software or a software component. The assessment of aspect oriented software and a core asset differs from the traditional software or component. There is need to develop a reusability model to relate the reusability attributes of aspect oriented software product line assets. This research work is an effort towards the development of reusability attribute model for software product line development using aspect oriented techniques. © 2010 IEEE.
