We propose to integrate goal-oriented requirements language i* with concepts from problem frames (PF). The integration of goal and problem makes it possible to address designer's subjective intentions and the physical constraints from the environment at the same time. We illustrate the proposed approach with the meeting scheduler example
A vision is presented for fusing quantitative requirements analysis with model-based systems engineering. This vision draws upon and combines emergent themes in the engineering milieu. "Requirements engineering" provides means to explicitly represent requirements (both functional and non-functional) as constraints and preferences on acceptable solutions, and emphasizes early-lifecycle review,...
Identification of crosscutting concerns at the requirements level is important for the modularization and evolution of requirements, and has attracted many research interests. This paper proposes a feature-oriented approach to the identification of crosscutting requirements based on feature dependency analysis. In this approach, features are used as basic elements to organize the requirements space,...
Terminological interference occurs in requirements engineering when stakeholders vary in the concepts they use to understand a problem domain, and the terms they use to describe those concepts. This paper investigates the use of Kelly's repertory grid technique (RGT) to explore stakeholders' varying interpretations of the labels attached to softgoals in a goal model. We associate softgoals with stakeholders'...
Increasingly, dynamically adaptive systems (DASs) are addressing complex problems that require a high degree of assurance. The inherent complexity of DASs and the safety critical applications they are addressing necessitates rigorous requirements engineering (RE). This problem is further complicated by the multiple stakeholders involved in the RE process. Berry et al. have identified four levels of...
The success of a task relies on the expertise of its owner to a great degree. But what is the anticipated expertise? In what areas? Our research intends to investigate the skill sets anticipated of requirements engineers. This paper presents a model of the varying levels of RE expertise within the context of the main RE domains. Identifying the layers of RE expertise can provide more realistic expectations...
This paper review and discuss software product management as a discipline, the need for it, and how it relates to RE. Given the relevance of product management in IT and software companies, and the rather unexplored body of knowledge in this field, the panel delivers a brief overview of software product management and its relationship to requirements engineering. Specifically the panel builds upon...
Understanding and supporting the interaction between software requirements and architectures remains one of the challenging problems in software engineering research. Our aim is to be able to derive architectural models in concert with multi-agent system requirements specifications. In this paper we present an approach to derive multi-agent systems architecture from requirements using social analysis...
This paper reports a systematic review of empirical studies concerning the effectiveness of elicitation techniques, and the subsequent aggregation of empirical evidence gathered from those studies. The most significant results of the aggregation process are as follows: (I) interviews, preferentially structured, appear to be one of the most effective elicitation techniques; (2) many techniques often...
Many patients today access the Internet for comprehensive hospital information and hospital selection. Yet medical expertise is not the only selection criterion for those seeking medical help. Excellent care, additional services, trust, and an appealing atmosphere in a clinic also play a role. In the competition among hospitals, the question is how a clinic should ideally present itself on the Web...
We present a novel technique that automatically alerts authors of requirements to the presence of potentially dangerous ambiguities. We first establish the notion of nocuous ambiguities, which are those that are likely to lead to misunderstandings. We test our approach on coordination ambiguities, which occur when words such as and or are used. Our starting point is a dataset of ambiguous phrases...
In the United States, federal and state regulations prescribe stakeholder rights and obligations that must be satisfied by the requirements for software systems. These regulations are typically wrought with ambiguities, making the process of deriving system requirements ad hoc and error prone. In highly regulated domains such as healthcare, there is a need for more comprehensive standards that can...
This vision paper reflects on the nature and status of requirements engineering as a science, based on recent RE journal articles on methodological foundations and research classification such as (R. Wieringa, et al., 2006). We put this discussion into the wider perspective of ongoing debates in other areas, including social and natural sciences methodology, IS and design research. We propose a new...
