In this paper, we introduce the application of rigorous analysis procedures to goal models in order to provide several benefits beyond the initial act of modelling. Such analysis can allow modellers to assess the satisfaction of goals, facilitate evaluation of high-level design alternatives, help analysts decide on the high-level requirements and design of(More)
The elicitation, modeling and analysis of requirements have consistently been one of the main challenges during the development of complex systems. Telecommunication systems belong to this category of systems due to the worldwide distribution and the heterogeneity of today’s telecommunication networks. Scenarios and use cases have become popular for(More)
In November 1999, the International Telecommunication Union (ITU-T, SG 17) initiated a question on the standardization of a User Requirements Notation (URN) for complex reactive, distributed, and dynamic systems and applications. URN is intended to be standardized by September 2003. This paper presents the motivations behind URN, its objectives, and the(More)
Business intelligence (BI) offers tremendous potential for business organizations to gain insights into their day-to-day operations, as well as longer term opportunities and threats. However, most of today’s BI tools are based on models that are too much data-oriented from the point of view of business decision makers. We propose an enterprise modeling(More)
Business organizations continuously monitor their environments, looking out for opportunities and threats that may help/hinder the fulfilment of their objectives. We are interested in strategic business models that support such governance activities. In this paper, we focus on the concept of composite indicator and show how it can be used as basic building(More)
Functional scenarios describing system views, uses, or services are a common way of capturing requirements of distributed systems. However, integrating individual scenarios in different ways may result in different kinds of unexpected or undesirable interactions. In this paper, we present an innovative approach based on the combined use of two notations.(More)
Our project is concerned with how dynamic agencies (sets of collaborating agents that vary their composition and collective behaviour over time) may be used to resolve demanding telecom problems in a flexible manner. Feature interaction (FI) is being studied as an instance of such problems for which dynamic agencies may be an appropriate solution. In our(More)
