An Agile Mda Approach for Executable Uml Structured Activities

Agile processes allow developers to construct, run and test executable models in short, incremental, iterative cycles. However, the agile development processes tend to minimize the modeling phase and the usage of UML models, because UML is a “unified” (too general) language with a lot of semantic variation points. The current version of UML together with its Action Semantics provide the foundation for building object-oriented executable models. But, constructing executable models using the existing tools and the current standard notations is a tedious task or an impossible one because of the UML semantic variation points. Agile MDA processes try to apply agile principles in the context of executable models. This paper presents a procedural action language for UML structured activities that allows developers to apply agile principles for executable models that contains structured activities. New graphical notations for structured activities are also introduced for rapid creation of tests and procedures.
