As information systems become more complex and widespread, their quality becomes a more and more important concern in their development. Therefore, requirements for software product quality should be treated in the same way as functional requirements, however it involves additional effort and extra costs. To ensure product quality two basic approaches can be considered: the first based on the e...

This article proposes a model for identifying quality requirements based on three different views of quality. By specifying quality requirements in this manner, the framework establishes quailty requirements that can be quanitfied and measured as part of an overall quality assurance program. This results in two levels of quality: one at the system level that ensures a quality software product a...

In model-based development, the development effort is centered around a formal description of the proposed software system—the “model”. This model is derived from some high-level requirements describing the expected behavior of the software. For validation and verification purposes, this model can then be subjected to various types of analysis, for example, completeness and consistency analysis...

This paper discusses an approach for the top-down composition of software architectures. First, an architecture is derived that addresses functional requirements only. This architecture contains a number of variability points which are next filled in to address quality concerns. The quality requirements and associated architectural solution fragments are captured in a so-called Feature-Solution...

This paper introduces a structured goal-oriented agent-based process modelling framework, where advanced requirements engineering techniques are combined with software quality modelling approaches, to provide an environment within which the stakeholders and the analysts can easily cooperate to discover, verify and validate the new IT system requirements. It forces and assists the stakeholders, ...

Recently, there has been an increase of reported security incidents hitting large software systems. Such incidents can originate from different attackers exploiting vulnerabilities of different parts of a system. Hence, there is a need for enhancing security considerations in software development. It is crucial for requirements engineers to identify security threats early on, and to refine the ...

In requirements engineering, properties of the environment and assumptions about it, called domain knowledge, need to be captured in addition to exploring the requirements. Despite the recognition of the significance of capturing and using the required domain knowledge, it might be missing, left implicit, or be captured inadequately during the software development. This results in an incorrect ...

Information Quality (IQ) is particularly important for the efficient performance of any system. Despite this, most of the Requirements Engineering (RE) frameworks either ignore IQ needs, or they deal with them as mere technical issues, i.e., they do not consider the social and organizational aspects that underlie such needs. This paper summarizes the experience of the authors in modeling and an...

In this paper, we propose a resource management system in Grid computing in order to specify system Quality of Service (QoS) requirements for dynamic and complex emerging applications. Our approach is based on the functional dependency among application components to specify the probability of system QoS requirements for the emerging application. Experimental results show that our application s...
