    Concern-Oriented Software Design
    (Springer, 2013) Alam, Omar; Kienzle, Jorg; Mussbacher, Gunter
    There exist many solutions to solve a given design problem, and it is difficult to capture the essence of a solution and make it reusable for future designs. Furthermore, many variations of a given solution may exist, and choosing the best alternative depends on application-specific high-level goals and non-functional requirements. This paper proposes Concern-Oriented Software Design, a modelling technique that focuses on concerns as units of reuse. A concern groups related models serving the same purpose, and provides three interfaces to facilitate reuse. The variation interface presents the design alternatives and their impact on non-functional requirements. The customization interface of the selected alternative details how to adapt the generic solution to a specific context. Finally, the usage interface specifies the provided behaviour. We illustrate our approach by presenting the concern models of variations of the Observer design pattern, which internally depends on the Association concern to link observers and subjects.

    TouchRAM: A Multitouch-Enabled Tool for Aspect-Oriented Software Design
    (Springer, 2012) Abed, Wisam Al; Bonnet, Valentin; Schottle, Matthias; Yildirim, Engin; Alam, Omar; Kienzle, Jorg
    This paper presents TouchRAM, a multitouch-enabled tool for agile software design modeling aimed at developing scalable and reusable software design models. The tool gives the designer access to a vast library of reusable design models encoding essential recurring design concerns. It exploits model interfaces and aspect-oriented model weaving techniques as defined by the Reusable Aspect Models (RAM) approach to enable the designer to rapidly apply reusable design concerns within the design model of the software under development. The paper highlights the user interface features of the tool specifically designed for ease of use, reuse and agility (multiple ways of input, tool-assisted reuse, multitouch), gives an overview of the library of reusable design models available to the user, and points out how the current state-of-the-art in model weaving had to be extended to support seamless model reuse.
