Cloud computing represents a solution for applications with high scalability needs where usage patterns, and therefore resource requirements, may fluctuate based on external circumstances such as exposure or trending. However, in order to take advantage of the cloud’s benefits, software engineers need to be able to express the application’s needs in quantifiable terms. Additionally, cloud provi...

Requirements engineering plays an essential role in software development. Requirements are prescriptive statements that express situations to be enforced by a system in terms of its effects on its environment. There have been many discussions of functional versus non-functional requirements, of hard-goals versus soft-goals, of non-functional and quality requirements versus soft-goals. Quality r...

In this paper, we introduce a catalogue template as one of the building blocks for a repository of metrics. Particularly, starting from a conceptual quality framework, we thoroughly discuss a catalogue template for product metrics instantiating it with some Web metrics. A catalogue of metrics basically allows evaluators and other stakeholders to have a consultation and reuse mechanism, which st...

Non-functional Requirements (NFRs) such as software quality attributes, software design constraints and software interface requirements hold crucial information about the constraints on the software system under development and its behavior. NFRs are subjective in nature and have a broad impact on the system as a whole. Being distinct from Functional Requirements (FR), NFRs are dealt with speci...

(discussion facilitator and rapporteur Jose Borbinha) The Problem A system is a collection of components organized to accomplish a specific function or set of functions [1]. In each moment the systems’ functions are perceived as outputs resulting from the combination of the state of its information model, of its inputs, and of the behavioural model defined for that system. We can classify the...

background: according to quality transformation of services during the time, the quality requirements and standards also change and recognition of these requirements and transformation process can assist in recognizing the quality dimensions of services. the aim of this research was to explain the transformation process, requirements and quality dimensions of services in hospitals.   methods: t...

For many years, the software industry has been applying different types of reviews on their requirements documents to identify and remove defects that would otherwise propagate in the development life cycle, leading to rework and extra cost to fix at later phases. An inspection is a review technique known to be efficient at identifying defects but, like any other review technique, it does not g...
