Information quality frameworks are developed to measure the quality of information systems, generally from the designers’ viewpoint. The recent proliferation of e-services and e-learning particularly raises the need for a new quality framework in the context of e-learning systems. This paper proposes a new information quality framework, with 14 information quality attributes grouped in three qu...

Reliability is always important in all systems but sometimes it is more important than other quality attributes, especially in mission critical systems where the severity of consequence resulting from failure is very high. Software reliability engineering is focused on comprehensive techniques for developing reliable software and for proper assessment and improvement of reliability. Reliability...

Good software architecture is critically important for successful software development. The software architecture can be defined as a set of architectural design decisions. However, the effort for acquiring good software architecture currently lacks of interest and experience in architectural design decisions. For this reason, during acquiring good software architecture, it is difficult to eval...

Improving modularity and reusability are two key objectives in object-oriented programming. These objectives are achieved by applying several key concepts, such as data encapsulation and inheritance. A class in an object-oriented system is the basic unit of design. Assessing the quality of an object-oriented class may require flattening the class and representing it as it really is, including a...

This paper attempts to compare the classification of quality attributes using Kano’s method and the service gaps method proposed by Kong and Muthusamy (2011). Expectation and perception data from 80 articles were systematically reviewed. Only two articles with classification of quality attributes by Kano’s method were identified. Four service quality factors were apparent from this study, and e...

Green software development is a relatively new research area within green IT. Software development industry has started getting pressure from regulators to consider green software development. As a result, green attributes of software products are gaining importance as quality attributes. In this study, we evaluate environmental sustainability and software quality criteria using a well-known mu...

Software variability has received research attention. However, only a few studies address the issue of quality attribute variability within software product families. This paper describes the ongoing research on quality attribute variability within a software product family architecture. We motivate the research topic by identifying three different situations in which quality attributes may var...

. In order to improve the quality of service co-production, both academics and managers have pointed out the pivotal role of Front line Employees (FLEs) in improving the service experience. However, few studies have simultaneously examined the quality perceptions of each group. Do FLEs perceive service quality in the same way as their customers? If this is the case, service quality itself will ...

Why has there been so little progress in the quantitative evaluation of those quality attributes concerned with software design? This paper seeks to provide an answer by arguing that progress is dependent on the adoption of a programme of cumulative empirical research. Such a programme consists of original empirical research, independent replication to investigate and verify original results, a...

This paper describes the status and technical progress of the INCITS W1.1 Text and Line Quality ad hoc team. The team has defined the scope of the work and developed several perceptual sub-attributes which comprise the Text Quality and Line Quality attributes, together with preliminary drafts of test patterns suitable for their quantification.
