Due to the budgetary deadlines and time to market constraints, it is essential to prioritize software requirements. The outcome of requirements prioritization is an ordering of requirements which need to be considered first during the software development process. To achieve a high quality software system, both functional and nonfunctional requirements must be taken into consideration during th...

For many years systems engineers have produced traditional system requirements specifications containing shall-statement requirements. The rapid adoption of use case modeling for capturing functional requirements in the software community has caused systems engineers to examine the utility of use case models for capturing system-level functional requirements. A transition from traditional shall...

Identification of non-functional requirements is important for successful development and deployment of the software product. The acceptance of the software product by the customer depends on the non-functional requirements which are incorporated in the software. For this, we need to identify all the non-functional requirements required by all stakeholders. In the literature not many approaches...

On an individual requirement by requirement basis, quality requirements are typically much more important than functional requirements because they most strongly drive the architecture of software-intensive systems. Thus, it is how well the quality requirements are engineered and implemented that tends to determine the success or failure of mission critical systems. Yet, missing or poorly speci...

Recently, the impact of design patterns on software quality has attracted a gradual attention since design patterns encapsulate valuable knowledge to resolve design problems and improve design quality. As an attempt towards the investigation of applying goals and design patterns to realize the model transformation, we proposed, in this paper, a goal-driven model transformation by applying desig...

Recently, the growing popularity of model driven frameworks and methodologies, as well as the Model Driven Architecture (MDA) initiated by Object Management Group (OMG) has implied an increasing focus on model transformation. Meanwhile, the impact of design patterns on software quality has attracted a gradual attention since design patterns encapsulate valuable knowledge to resolve design probl...
