The Unified Modeling Language (UML) does not fully address the needs of some important modeling domains, including goals and non-functional requirements (NFR). However, UML can be extended and tailored through the definition of profiles. In this paper, we propose a UML profile for the Goal-oriented Requirement Language (GRL), the goal/NFR notation of the User Requirements Notation (URN), recent...

The performance of current transaction processing systems largely depends on human experts for administration and tuning. These experts have to specify a multitude of internal control parameters in different subsystems for which finding appropriate settings is very difficult. Another shortcoming of manual system administration lies in its inability to quickly react to changing system and worklo...

This paper presents an extended version of GoalOriented Requirements Analysis Method called AGORA, where attribute values, e.g. contribution values and preference matrices, are added to goal graphs. An analyst attaches contribution values and preference values to edges and nodes of a goal graph respectively during the process for refining and decomposing the goals. The contribution value of an ...

Software Cockpits, also known as Software Project Control Centers, support the management and controlling of software and system development projects and provide means for quantitative, measurement-based project control. Currently, many companies are developing simple control dashboards that are mainly based on Spreadsheet applications. Alternatively, they use solutions providing a fixed set of...

Current research in service-oriented computing (SoC) is mainly about technology standards for SoC and the design of software components that implement these standards. In this paper we investigate the problem of requirements engineering (RE) for SoC. We propose a framework for goaloriented RE for e-services that identifies patterns in service provisioning and shows how to compose business model...

The use of Commercial Off-The-Shelf (COTS) components is becoming a strategic need because they offer the possibility to build systems at reduced costs and within shorter development time. Having efficient and reliable COTS components selection methods is a key issue not only for exploiting the potential benefits of this technology, but also for facing the problems and risks involved. Searching...

Software product-line engineering is a method for improving the efficiency and effectiveness of software development. Introducing such a method into an industrial software development environment is potentially of great benefit, but one cannot afford to stop product development while doing so. Rather, in Avaya we apply an incremental adoption strategy and therefore must identify which part(s) o...

End-to-end dialog systems, in which all components are learnt simultaneously, have recently obtained encouraging successes. However these were mostly on conversations related to chit-chat with no clear objective and for which evaluation is difficult. This paper proposes a set of tasks to test the capabilities of such systems on goal-oriented dialogs, where goal completion ensures a well-defined...
