Dependability and security are among quality concerns that require a software to be decomposed into separate units isolated from each other. However, it appears that this decomposition is usually not aligned with the decomposition based on functional concerns. As a result, introducing module isolation forced by quality attributes, while preserving the existing decomposition, is not trivial and requires a substantial refactoring effort. In this work, we introduce an approach and a toolset to predict this effort prior to refactoring activities. As such, a selection can be made among potential decomposition alternatives based on quantitative estimations. These estimations are obtained from scalable analysis of module dependencies based on a graph database and reusable query templates. We discuss our experiences and evaluate our approach on a code base used in a commercial Digital TV and Set-top Box software.engrestrictedAccessbookPart862730030700034508300002610.1007/978-3-319-09970-5_26Software architectureReverse engineeringRefactoringModule isolationEffort estimationDependabilitySecurity2-s2.0-84958549687
