A Concern-Oriented Requirements Engineering Model

摘要: Traditional requirements engineering approaches suffer from the tyranny of dominant decomposition, with functional serving as base decomposition and non-functional cutting across them. In this paper, we propose a model that decomposes in uniform fashion regardless their or nature. This makes it possible to project any particular set on range other requirements, hence supporting multi-dimensional separation. The projections are achieved through composition rules employing informal, often concern-specific, actions operators. approach supports establishment early trade-offs among crosscutting overlapping requirements. This, turn, facilitates negotiation decision-making stakeholders.
