In traditional software engineering research and practice, requirements are classified either as functional or non-functional. Functional requirements consist of all functions the system-to-be ought to support, and have been modeled in terms of box-and-arrow diagrams in the spirit of SADT. Non-functional requirements include desired software qualities for the system-to-be and have been described either in natural language or in terms of metrics. This orthodoxy was challenged in the mid-90s by a host of proposals that had a common theme: all requirements are initially stakeholder goals and ought to be elicited, modeled and analyzed as such. Through systematic processes, these goals can be refined into specifications of functions the system-to-be needs to deliver, while actions assigned to external actors need to be executed. This view is dominating Requirements Engineering (RE) research and is beginning to have an impact on RE practice. We propose a next step along this line of research, by adopting the concept of conditional commitment as companion concept to that of goal. Goals are intentional entities that capture the needs and wants of stakeholders. Commitments, on the other hand, are social concepts that define the willingness and capability of an actor A to fulfill a predicate ϕ for the benefit of actor B, provided B (in return) fulfills predicate ψ for the benefit of actor A. In our conceptualization, goals are mapped to collections of commitments rather than functions, qualities, or actor assignments. We motivate the importance of the concept of commitment for RE through examples and discussion. We also contrast our proposal with state-of-theart requirements modeling and analysis frameworks, such as KAOS, MAP, i* and Tropos.

“…users, services, products, transactions), should be expressed and modelled at a level that enables mutual understanding between requirements engineers and stakeholders so as to avoid the socio-technical mismatch in communication that can delay and harm the system development: requirements analysis is one of the most important phase of software development. At this stage many problems arise because technical issues considerations have to be taken into account together with social and organizational ones: there is need for conceptual models and tools that are closer to the domain (roles, values) instead of the information system/program structure (classes, methods) [7]. The aim of a conceptual model for reputation system is to model those features that compose the value delivered to/perceived by users and costumers.…”

VDML4RS: a tool for reputation systems modeling and design

Reputation has a great influence on interactions between system providers and users (e.g. in e-commerce). Despite that, reputation systems implemented so far show many deficiencies and suffer from reliability problems. One of the causes is the lack of appropriate software engineering methodologies dedicated to requirements collection and design of reputation systems. On the other hand, business process modeling, service design and reputation system modeling share many needs (represent a variety of entities involved in the related domains), aims (improve services/business in order to meet the user's needs) and problems (they all involve stakeholders with very different backgrounds and skills). Starting from the intuition above, this paper proposes VDML4RS a tool for conceptual modeling of reputation systems. The aim is to provide a tool to represent reputation requirements of the system-to-be from the very beginning in the software development allowing mutual understanding between requirements engineers and stakeholders avoiding the socio-technical mismatch in communication that can delay and harm the development.

Abstract. We address the challenge of adaptation in open systems. Open systems are characterized by interactions among autonomous and heterogeneous participants. In such systems, each participant is a locus of adaptation; nonetheless, a participant would typically have to interact with others in order to effect an adaptation. Existing approaches for software adaptation do not readily apply to such settings as they rely upon control-based abstractions. We build upon recent work on modeling interaction via social commitments. Our contributions in this paper include (1) formalizing the notion of a participant's strategy for a goal not just in terms of goals and plans, but also in terms of the commitments required, and (2) a conceptual model and framework for adaptation built around this notion of strategy that allows using arbitrary strategy selection criteria-for example, trust. We illustrate our contributions with examples from the emergency services domain.
