Trade-off analysis through goal model evaluation has been a valuable tool for requirements elicitation and analysis. This is also true in the context of reuse. When goal models are used to describe reusable artifacts and to represent the impacts of reusable artifacts on high-level goals and qualities, they can guide the selection of reusable artifacts to build reuse hierarchies. In previous work,...
Goal models help elicit, specify, analyze, and validate requirements as they capture hierarchical representations of system requirements, possible solutions, stakeholder objectives, and their relationships. In the early requirements phase, goal models aid requirements engineers in understanding the goals of stakeholders and exploring solution alternatives based on their impact on these goals. Despite...
A fundamental task when reusing software artifacts is to determine the most appropriate artifact for the current reuse context. Goal modeling allows modelers to capture the advantages and disadvantages of reusable candidate artifacts, which in turn helps reason about the most appropriate candidate artifact. However, goal models are rarely used in isolation for the description of an artifact, but are...
A new unit of encapsulation called the concern is at the center of Concern-Orientation. Building on techniques for advanced Separation of Concerns, from Model-Driven Engineering, and from Software Product Lines, Concern-Orientation is a reuse paradigm that stipulates the use of three interfaces to enable broad, generic reuse: the variation, customization, and usage interfaces. Higher-level concerns...
