An approach, named Aspecting, is proposed for eliciting aspects in Object Oriented systems and subsequently re-factoring these systems as aspect oriented systems. The approach has three phases: Understand the System Functionality, Treat the Interests and Compare the Object Oriented System with the Aspect Oriented System. Each phase is presented with the details to be observed by the software engineer for the migration of the systems to be made safely and to obtain a quality product. Techniques of separation of concerns and aspect oriented programming are used in three prospective study cases, in order to induce formulating the approach. Guidelines are established to model the concerns identified, using class diagrams in UML notation. Other guidelines govern the implementation of concerns as aspects, using the Aspect J language. The use of regression tests in the system after the system code reorganization now implemented with aspects, for checking if the original functionality has been preserved in the migration, completes the approach. A fourth study case, for illustrating the approach application, is also presented.
