Improvements in requirements traceability (RT) are essential for developing better quality software systems. Based upon empirical investigations with practitioners, and an extensive survey of techniques and tool support for requirements engineering (RE), we explain why conventional RT can only support limited improvements in quality, and suggest extensions required to provide further improvemen...

Being able to reduce the gap between Requirements Engineering and Software Engineering is crucial to foster the developments of better Informations Systems that more precisely adresses the organizational needs of the stakeholders. One of the key factor toward this objective is adopting methodologies in which the the conceptual level of Requirements Engineering techniques is raised, so that form...

In order to integrate requirements into the current Model-Driven Engineering (MDE) approach, the traditional document-based requirements specification process should be changed into a requirements modelling process. To achieve this we propose a requirements metamodel called REMM (Requirements Engineering MetaModel) which includes the elements that should appear in a requirements model (requirem...

Context. Requirements changes are unavoidable in any software project. Requirements change over time as software projects progress, and involved stakeholders (mainly customers) and developers gain better understanding of the final product. Additionally, time and budget constraints prevent implementing all candidate requirements and force project management to select a subset of requirements tha...

Goal and agent orientation in Requirements Engineering has been recognized as a very promising approach. In fact, by adopting notions as those of Agent, Goal, Intentional Dependency and so on, it is possible to smoothly refine high-level requirements into detailed descriptions of the system-to-be. This paper introduces a requirements engineering framework based on the notions of Agent, Goal, an...

This paper describes our efforts at providing hypermedia-based support for requirements analysis. We present: an overview of our concept of hypermedia-based support for the requirements analysis process; our experiences using this technology; and some remaining technological challenges highlighted by our experiences. Our analysis of requirements analyst's needs indicates several productivity re...

In this paper a short (16 hours) newly designed course on practical software engineering is described. This course has been designed according to specific objectives (i.e. orientation to the practice, generality and adequacy to the current software engineering community trends) and focused on the requirements elicitation, documentation, and analysis topics. In the course an innovative tool for ...

We adapt in this paper an analysis-revision cycle to the SCTL-MUS methodology which we will use to support the modification and evolution of requirements specifications in a multi-perspective environment. We take advantage of using our approach in the analysis and revision phases, being able to translate the diagnostic information into system requirements refinements close to the system domain ...

Multiple viewpoints are often used in Requirements Engineering to facilitate traceability to stakeholders, to structure the requirements process, and to provide richer modelling by incorporating multiple conflicting descriptions. In the latter case, the need to reason with inconsistent models introduces considerable extra complexity. This paper describes an empirical study of the utility of mul...

The Inquiry Cycle is a generic process model for conducting requirements elaboration. It consists of three activities: requirements expression, discussion and commitment. This paper describes an evaluation of the Inquiry Cycle model and a support tool, Tuiqiao, in the requirements analysis phase of a real project, a proposed commercial consumer information service based on Internet. The extent ...
