Separation of concerns has been central to software engineering for decades, yet its many advantages are still not fully realized. A key reason is that traditional modularization mechanisms do not allow simultaneous decomposition according to mu ltiple kinds of (overlapping and interacting) concerns. This workshop was intended to bring together researchers working on more advanced modularization mechanisms, and practitioners who have experienced the need for them, as a step towards a common understanding of the issues, problems and research challenges. Keywords Separation of concerns, decomposition, composition 1 SEPARATION OF CONCERNS Separation of concerns [5] is at the core of software engineering, and has been for decades. In its most general form, it refers to the ability to identify, encapsulate, and manipulate only those parts of software that are relevant to a particular concept, goal, or purpose. Concerns are the primary motivation for organizing and decomposing software into...
