This paper presents a Goal Oriented Approach for the Definition of a Business Process Requirement Model, taking into account the level of importance and constraints inherent in these requirements. The level of importance of a goal is the credit which the user associates to it, while constraints are non-functional needs related to that which this goal must(More)
In a business environment that is constantly evolving the management of knowledge is becoming increasingly important. In particular the shareability and repeatability of experience gained in change situations can prove an invaluable tool for the evolving enterprise. We advocate the use of the pattern paradigm as a means to capture and disseminate this type(More)
To develop quality software and systems, both functional and non-functional requirements need to be taken into account at the highest level of abstraction. However the issue of relationships between non-functional requirements and functional requirements has been rarely addressed. In this article, we outline an extension of the SysML requirements meta-model(More)
The aim of reuse approaches is to improve requirements engineering activities specially requirements elicitation. In this paper, we propose a metamodel allowing the formalization of domain knowledge by elaborating knowledge fragments. A domain represents a class of systems and a knowledge fragment is a triplet <goal, business rule, conceptual fragment>(More)
This work is done as part of the Tacos project 1 whose aims is to define a component-based approach to specify trustworthy systems from the requirements phase to the specification phase, in the Cycab transportation domain. This paper mainly deals with the improvement of requirements elicitation in the context of Cycab domain. For that purpose, we propose to(More)
This paper describes a work-in-progress in the framework of a research project aiming at defining traceability links between requirements phase and specification phase. The main idea is to extend the SysML language with the most relevant concepts of commonly used requirements engineering approaches. In this paper, we first define a set of SysML extensions(More)
