As software complexity grows and clients demand higher quality software, quality requirements can no longer be considered to be of secondary importance. Thus eliciting, specifying, prioritising and validating quality requirements is a pre-requisite to the development of effective and efficient information systems. Despite the critical importance of quality requirements, there is a considerable ...

In this paper, we propose a tool for Requirements completeness analysis over requirements written in restricted Spanish. This tool materialize a method for requirements completeness based on a linguistic approach, more specifically based on semantic cases associated with verb senses. We also present the process for effectiveness of the tool, in completeness on several case studies, using precis...

IT industry needs reliable data about quality requirements to evaluate adequately systems and their architecture. The task is not easy due to nature of these requirements. In fact they are vague, difficult to define and often conflicting with other requirements. Today’s quality requirements management methods are dealing either with one quality requirement aspect (ex: FDAF framework for securit...

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...

Software architectural evaluation becomes a familiar practice in software engineering community for developing quality software. Architectural evaluation reduces software development effort and costs, and enhances the quality of the software by verifying the addressability of quality requirements and identifying potential risks and it provides assurance to developers that their chosen architect...

Quality of service (QoS) is an important issue in the design and management of web service composition. QoS in web services consists of various non-functional factors, such as execution cost, execution time, availability, successful execution rate, and security. In recent years, the number of available web services has proliferated, and then offered the same services increasingly. The same web ...
