MAP - mining architectures for product line evaluations

Product lines evolve out of existing products. In order to evaluate the potential of creating a product line from existing products, it is necessary to ´mine´ their architectures and analyze the commonalities and variabilities across those architectures. To manage the evaluation process in a disciplined way the paper introduces the MAP (Mining Architectures for Product Lines) method. MAP outlines a bottom-up approach for mining the architecture of the existing products, a top-down approach to mapping architectural styles and attributes onto the mined architectures and an approach to analyzing their commonalities and variabilities. It combines well-known architecture reconstruction and product line analysis techniques. A case study is presented showing the application of the method and its benefits are outlined
