A model for software product quality is defined. It has been formulated by associating a set of qualitycarrying properties with each of the structural forms that are used to define the statements and statement components of a programming language. These quality-carrying properties are in turn linked to the highlevel quality attributes of the International Standard for Software Product Evaluatio...

This study proposes perceived ‘Importance-Performance Analysis’ by simultaneously integrating ‘importance-performance analysis’ and Kano’s model in identifying key success factors. Kano’s model, which provides a two-dimensional view of quality, is a very useful tool to identify which customer requirements of a particular product or service might be more than the proportional satisfaction to cus...

This is a theoretical attempt to discover within the vast universe of data/information (D/I) quality dimensions the first invariants and principles of more lasting validity. It required a move from the internal (designers’) toward the external (users’), from the ontological to the teleological perspective and a full recognition of the relativity of quality within the context of decision situati...

Most of the quality models that are commonly practiced in the business world have been adapted and used in the education sector. In this paper, we proposed to look at the quality issue in higher education from the marketing perspective; that is, to first understand the customers’ needs via their perception of quality. The aim of our paper is to assess the quality attributes of higher education ...

Web conceptual models certainly represent a successful approach to the design of complex Web applications. Wrong uses of conceptual models may however introduce problems, which void the numerous advantages deriving from their exploitation in Web applications design. In this paper, we present a quality model for WebML, an XML-based Web conceptual model having a graphical notation. We also introd...

Misuse cases are like use cases, but with bad intent. They can be used when defining non-quality attributes. This paper describes the main concepts concerning misuse cases and shows ways to present them. A literature study is performed to find answers to research questions.

Scenario profiles are used increasingly often for the assessment of quality attributes during the architectural design of software systems. However, the definition of scenario profiles is subjective and no data is available on the effects of individuals on scenario profiles. In this paper we present the design, analysis and results of a controlled experiment on the effect of individuals on scen...

Variability is a key factor of most systems. While there are many works covering variability in functionality, there is a research gap regarding variability in software qualities. There is an obvious imbalance between the importance of variability in the context of quality attributes, and the intensity of research in this area. To improve this situation, the First International Workshop on VAri...

It is becoming more and more clear that architectural design is a crucial step in building complex software. Architectural design involves the first and most crucial design decisions to meet the expected quality attributes [1]. Dealing with concerns that influence important quality attributes asks for an architecture-centric approach. In this paper we propose architectural concerns as basic con...
