Web services have emerged as an important technology nowadays. There are two kinds of requirements that are crucial to web service composition, which are functional and non-functional requirements. Functional requirements focus on functionality of the composed service, e.g., given a booking service, an example of functional requirements is that a flight ticket with price higher than $2000 will ...

The quality of an architectural design of a software system has a great influence on achieving non-functional requirements of a system. A regular software development project is often influenced by non-functional factors such as the customers' expectations about the performance and reliability of the software as well as the reduction of underlying risks. The evaluation of non-functional paramet...

nowadays a growing number of implementing informationtechnology service management (itsm) frameworks proves the trends toimprove the it services and processes in organizations. in order toimplement an itsm projects successfully in an organization, it isessential to select a suitable itsm solution. evaluation and selection ofthe itsm software packages is complicated and time consuming decisionma...

The goal oriented requirements analysis approaches have been introduced to compare non-functional requirements (NFR), such as safety and security. Several approaches to manage goal attributes have also been proposed to evaluate NFR goals quantitatively. In this paper, the quantitative weighted softgoal is proposed based on the Softgoal Interdependency Graphs (SIG) that helps engineers evaluate ...

One of the most important problems in product design using quality function deployment is how to capture true customer requirements. In this research, we develop systematic methods, processes, and techniques for eliciting complete, consistent, nonredundant, and true customer requirements from multiple perspectives. It covers from requirements acquisition, requirements extraction to requirements...

background: determining quality requirements and quality dimensions is one of the most reliable ways of providing high quality services. the objective of the present study was to investigate the association between quality requirements and quality dimensions according to the points of view of physicians, nurses, and patients. materials and methods: this descriptive study was carried out in hosp...

Requirements traceability helps to ensure that a requirements specification is aligned with the intended stakeholders’ needs. Such alignment should involve the consideration of why such needs arise, in terms of what problems the stakeholders are faced with, and what kinds of software system may help alleviate or eliminate the problems. However, little work can be found on requirements traceabil...
