Modeling Variabilities from Software Process Lines with Compositional and Annotative Techniques: A Quantitative Study

摘要

A software process line (SPrL) represents a set of software process that share a common base of roles, practices, activities, and artifacts. Various individual approaches have been proposed to modeling software process lines. The majority of these approaches can be characterized as compositional or annotative approaches. This work presents a quantitative comparative study of the EPF Composer compositional approach, and the GenArch-P annotative approach. Our study has considered internal attributes of the specification of SPrLs, such as modularity, size and complexity. Our study has found that the GenArch-P approach presented better results in terms of size and complexity attributes, while the EPF Composer improve the modularity of SPrL specifications. We also envisioned a possible integration of the two approaches.
