Model transformation approach allows us to develop automatic and flexible solutions for the software evolution. Application of model transformation concepts was shown on a case study of a generic framework for traceability in object-oriented designs. Traceability analysis in the framework is based on discovering traceability relationships among model elements and identifying dependency areas for given initial elements. The analysis is controlled by a set of rules that should be easily modified ac- cording to the project notation, application domain, etc. Three transformations within the framework were considered: the input transformation of any m odel to the internal format, the traceability analysis generating a dependency area for a given model, a nd the output transformation of the resulting de- pendency area. They can be realized as model-to-m odel transformations with respect to their meta- models and in accordance to the independently speci fied transformation rules. The language and tools of the QVT standard proposed by the OMG were a pplied in the input and output transformations. In the remaining transformation, traceability rules were de fined as automata with transitions labeled with conditions and actions.
