Requirements Modelling for Multi-Stakeholder Distributed Systems: Challenges and Techniques
نویسندگان
چکیده
Multi-stakeholder distributed systems (MSDS) are distributed systems in which subsets of the nodes are designed, owned, or operated by distinct stakeholders. New computing paradigms such as service-oriented computing mean that challenges posed by MSDS will be more dominant in the future. These challenges have particular implications for requirements engineering (RE). For example, in MSDS decisions about the system architecture are increasingly shifted from system design to system operation. In this paper we discuss the characteristics of MSDS and present a framework for structuring the MSDS research issues. Using an example we illustrate that existing RE approaches for goal modelling, variability modelling, and negotiation techniques can be used successfully if used in an integrated manner to address the identified challenges.

متن کاملClassifying Requirement Conflicts for Multi-Stakeholder Distributed Systems
Multi stakeholder distributed systems become more and more widespread and raise a lot of integration problems. One problem is that conflicts arise often only at runtime if a single system component is changed. The whole composition of systems then doesn’t behave like at least one of the stakeholders expects. The following paper provides a classification of the potential conflicts and gives some...

متن کاملUsing Speech Acts and Agent Architecture to Support Successful Stakeholder Requirements Negotiation
Speech act theory has been used on numerous occasions to create an underlying framework on which communication technologies can be built. Electronic mail filtering methods, communication support tools and modelling techniques using several variants of speech act theory have all been proposed in the last few years. Distributed organisations employ various communication methods in order to share ...
