Some Metrics for Accessing Quality of Product Line Architecture

Product line architecture is the most important core asset of software product line. vADL, a product line architecture description languages, can be used for specifying product line architecture, and also provide enough information for measuring quality of product line architecture. In this paper, some new metrics are provided to assess similarity, variability, reusability, and complexity of product line architecture. The main feature of our approach is to assess the quality of product line architecture by analyzing its formal vADL specification, and therefore the process of metric computation can be automated completely.
