Software Product Line (SPL) life cycle comprises a set of essential activities. Variability Management (VM) is one of its most important activities to the success of an SPL, especially those based on UML, as the solution space encompasses different diagrams and perspectives on variability. However, the lack of tools to support UML-based SPLs reflects difficulties in adopting this approach. This scenario motivated the development of SMartyModeling, an environment for engineering UML-based SPL. The SMartyModeling architecture was instantiated based on VMTools-RA, an existing reference architecture for software variability tools. VMTools-RA describes architectural requirements, elements and views on software variability, which aid one to instantiate variability tool architectures. The instantiation process started from the identification of requirements, selection of elements, modules, and visions of VMTools-RA, planning and design of the architectural solutions, implementation of modules and organization of features. We then analyzed the feasibility of adopting VMTools-RA for instantiating an specific tool architecture. In this sense, such instantiation is part of the development process of SMartyModeling, which includes the main activities related to VM. We also empirically evaluated SMartyModeling in three ways: (i) a field study to analyze the instantiation process and the decisions taken; (ii) a comparative experiment analyzing efficiency and effectiveness of SMartyModeling in relation to a general purpose UML tool; and (iii) an evaluation of aspects related to perceived ease of use and perceived usability. The results of such evaluations provide initial evidence VMTools-RA is feasible to instantiate specific architectures and SMartyModeling is feasible to support to VM for UML-based SPLs.
