GOAL, SOFT-GOAL AND QUALITY REQUIREMENT

Abstract

Requirements are input for the process of building software. Depending on the development methodology, they are usually classified into several subclasses of requirements. Traditional approaches distinguish between functional and non-functional requirements and the modern goal-based approaches use hard-goals and soft-goals to describe requirements. While non-functional requirements are known also as quality requirements, neither hard-goals nor soft-goals are equivalent to quality requirements. Due to the abstractness of quality requirements, they are usually described as soft-goals but soft-goals are not necessarily quality requirements. In this paper, we propose a way to clear the problematic ambiguity between soft-goals and quality requirements in goal-based context. We try to reposition the notion of quality requirement in the relations to hard-goals and soft-goals. This allows us to decompose a soft-goal into a set of hard-goals (required functions) and quality requirements (required qualities of function). The immediate applications of this analysis are quality-aware development methodologies for multi-agent systems among which QTropos is an example.
