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...

The development of Web Applications has some special characteristics, such as very short Time-to-Market, parallel development and requirements that are not prioritized. This makes it hard to address quality attributes in a systematic way, to prioritize requirements and to resolve conflicts between them. The use of trade-off methods such as QFD will help to prioritize the “right” requirements an...

This research proposes the use of an IPMAP for providing metadata about the source and processing of primary data, in order to enhance its believability and fitnessfor-use. We then derive a framework for assessing data quality-in-use from dual-process theories of human cognition. By applying a dual-process approach to data quality assessment, the model enables simultaneous evaluation of both ob...

PURPOSE The study investigated the extent to which differences existed between public attitudes of males versus females. METHOD One hundred adults, 50 males and 50 females, were chosen at random from each of 50 study samples comprising a total of 3371 respondents in a database archive who had completed the Public Opinion Survey of Human Attribute-Stuttering (POSHA-S). None of the database sam...

The drinkable yogurt marketplace is a competitive and growing category in the dairy industry. Understanding sensory differences is critical for understanding the product, and ultimately, consumer preference. The objective of this study was to identify and define the sensory characteristics of commercial drinkable yogurts and link these specific sensory attributes to consumer preferences among C...

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.
