The elicitation of end-user requirements is primarily focusing on the industry, where companies endeavor to discover and satisfy their customer’s requirements. Increasingly however, companies which are working in the same or in different fields are getting together, in order to do joint research and development, despite the fact that they may be potential competitors. These kinds of projects ha...

This paper introduces an approach to multi-perspective requirements engineering (PREview) which has been designed for industrial use and discusses our practical experience in applying PREview. We have developed a flexible model of viewpoints and, using examples from an industrial application, show how this can be used to organise system requirements derived from radically different sources. We ...

In the context of Requirements Engineering (RE), both goal-driven and scenario-based approaches have proven useful for eliciting, justifying and validating system requirements. In order to overcome some of the deficiencies and limitations of these approaches when used in isolation, proposals have been made to couple goals and scenarios together. The CREWS1-L'Ecritoire approach advocates bi-dire...

Software requirements are changed by various factors. Stakeholders that are analysed in traditional requirements engineering are mainly requesters or decision makers with regard to the requirements specifications. Such stakeholders are selected as intentional actors in the i* framework. The novel point of this paper is that we focus on the world of parties who are the environmental factors of t...

Computer systems are designed and used by humans. And human being is characterized, among other things, by emotions. Giving this fact, the process of designing and developing computer systems is, like any other facet in our lives, driven by emotions. Requirements engineering is one of the main phases in software development. In Requirements engineering, several tasks include acceptance and nego...

This paper considers the difficulties faced by the stakeholders in general requirements engineering (RE). These difficulties range from the complexity of requirements gathering to requirements presentation. Affordable visualization techniques have been widely implemented to support the requirements engineering community. However, no universal characteristics that could be associated with requir...

Requirements engineering is the practice of identifying and specifying system requirements to achieve a specific purpose. Government laws and regulations are written to achieve societal goals, and thus have a direct impact on system requirements and designs. Engineers and regulators need methods and tools to focus the discussion of legal compliance in terms of observable criteria to ensure that...

The principal task of requirements engineering is the definition of requirements that reflects the understanding of the problem. In this process different approaches for information elicitation may be used. In our case we show that the application of elicitation strategies in the right form can improve the evolution of an existing artifact. In this paper we show the evolution of an education ga...

This paper presents a web platform that applies concepts from the domain of Social Software to requirements engineering. The platform implements several community-oriented features that support collaboration and knowledge sharing and aim to foster the engagement of larger groups of stakeholders in the collection, discussion, development, and structuring of software requirements.

Requirements Evolution represents one of the major problems in developing computer-based systems. Current practice in Requirement Engineering relies on process-oriented methodologies, which lack of product features. The resulting scenario then is a collection of general methodologies, which do not take into account product features that may enhance our ability in monitoring and controlling Requ...
