Metrics and measures have always been the subject of quite a lot of research works in the Requirements Engineering (RE) community, including about intentional models of Goal-Oriented RE (GORE) such as those of i*. However, using recent developments of the Measurement Theory, in this paper we show that the concept of Measurement Framework (MF) for soft-systems is useful for the analysis of busin...

Access protection is an important requirement for systems, which handle confidential data. This paper describes an approach for the requirements engineering of an access protection using the example of an open system. A major problem of open systems is that many users with different roles access it. Moreover, the open system is connected to the Internet and has ports for connecting hardware lik...

A number of requirements engineering (RE) approaches have focused on addressing broadly scoped (non-functional) properties such as security, availability, etc. More recently, several aspect-oriented requirements engineering (AORE) approaches have been proposed to tackle both functional and non-functional requirements of a crosscutting nature. In this paper, we analyse how some well-known RE app...

Goal-Oriented Requirements Engineering (GORE) is an approach to requirements engineering dealing with intentionality in accordance with the relations among different actors. KAOS and i* (i-star) frameworks have been receiving many references as being important GORE proposals. This paper presents an conceptual analysis comparing characteristics of those methods giving examples related to actors’...

Goal-oriented requirements engineering aims at eliciting, elaborating, structuring, specifying, analyzing and documenting functional and non-functional requirements. This activity must include the involvement of final users of the system across the whole process to reduce the risk of misunderstanding the domain, missing important details and to increase the final value of the product. User-Cent...

Software Development has started experiencing the need of consideration of NFR (Non Functional Requirements) for producing high quality acceptable software. Mostly software engineering literature has considered only for testing Functional Requirements. In context of such a need this work attempts to consider NFR, resulting from quality concerns of stakeholder, along with their impact and effect...

Collaborative systems are becoming increasingly important, because they enable several users to work together and carry out collaboration, communication and coordination tasks. We have to highlight that, to perform these tasks, the users have to be aware of other users’ actions, usually by means of a set of awareness techniques. Usually, the specification of this set of techniques has to be don...

Scenarios have been used in many different ways to assist planning. They have been used for over 20 years in technological forecasting for corporate plans, in testing for the suitability of human-computer interfaces, in experimental gaming to explore decision-making processes, in preparing case-studies for management education, and for “surfacing” assumptions underlying strategic planning. One ...

ly. Then, a CASE tool extraction of the framework is introduced. Its motivation is argued, and synopses of its implementation are displayed. An introspective case study is provided to reinforce the overview of the suggested ontology in addition to displaying the CASE

Context: A collaborative system is a special kind of software whose users can perform collaboration, communication and collaboration tasks. These systems usually have a high number of non-functional requirements, resulting from the users’ need of being aware of other users with whom to collaborate, that is, the workspace awareness. Objective: This paper aims at evaluating two Requirement Engine...
