At the heart of a well-disciplined, systematic methodology that explicitly supports the use of commercial off-the-shelf (COTS) components is a clearly defined process for effectively using components that meet the needs of the system under development. In this paper, we present the CARE/SA approach that supports the iterative matching, ranking, and selection of COTS components. The components a...

Requirements elicitation for a new system requires extensive involvement with stakeholders who usually have varying aims, backgrounds and disciplines, and this process is complicated further if the system has critical security, or other non-functional requirements. Established approaches to the elicitation and analysis of functional and non-functional requirements are very different the former ...

ABSTRACT: Benchmarking is a critical activity in Web site development and has been employed for requirement analysis in a variety of Web site renewal and development projects. By comparing their current Web site with competitors’ cutting-edge sites, managers can attain improvement in quality. Despite the importance and popularity of benchmarking, however, the literature sheds lit tle light on t...

The idea of Information and Communication Technology for development (ICT4D) has been gathering momentum since last decade. It contributes to the development of social, political, and economic growth of the underprivileged group of populations especially in the context of developing countries. Requirements Engineering (RE) is the most sensitive from all other activities involve in the ICT4D pro...

An important aspect of the requirements engineering process is the specification of traceable, unambiguous and operationalizable non-functional requirements. This remains a non-trivial task due to the lack of well-documented, systematic procedures that facilitate a structured analysis of the qualitative data that is typically the input to this activity. This research investigates the developmen...

Use cases are widely used for functional requirements elicitation. However, security non-functional requirements are often neglected in this requirements analysis process. As systems become increasingly complex current means of analysis will probably prove ineffective. In the safety domain a variety of effective analysis techniques have emerged over many years. Since the safety and security dom...

A pervasive healthcare monitoring system (PHCMS) is an intrusive technology designed to provide supports to assist people with health problems. PHCMS could eventually lead to a fully monitored and supervised life within a home and thus reduce dependency of people towards healthcare institutions. Following implementation of such monitoring devices, elements of privacy, emotions and personal valu...

Representing and selecting patterns remains largely an empirical task. It is difficult to recognize when to apply a given pattern, as well as the consequences its application could generate. This creates the need for extensions to the existing pattern representation. Elsewhere, we have proposed an explicit representation of the forces involved in a pattern and their interrelationships. It inter...

A collaborative system is a software allowing several users to work together and carry out collaboration, communication and coordination tasks. To perform these tasks, the users have to be aware of other user’s actions, usually by means of a set of awareness techniques. However, when these systems have to be specified for development severe difficulties emerge to describe the requirements assoc...

System specifications should be refined to meet stakeholders’ requirements as much as possible, because the first specification does not satisfy all stakeholders in general. This paper presents a procedure to refine behavioral specification to satisfy stakeholders. Non-functional requirements are used for checking stakeholders’ satisfaction. With this procedure, stakeholder-dissatisfaction can ...
