Over the years, cumulative data have shown that maintenance is a major cost concern, as a matter of fact, a growing cost concern (Pigosky, 1997). The maintainability of a system seems to have much influence on the ease or difficulty to implement changes. A consensus has emerged that the maintainability of a software system is dependent on its design (Rombach, 1990), in the procedural paradigm a...

In this study, we investigated the adoptability of software quality measures for healthcare process measurement. Quality measures of ISO/IEC 9126 are redefined from a process perspective to build a generic healthcare process quality measurement model. Case study research method is used, and the model is applied to a public hospital's Entry to Care process. After the application, weak and strong...

Red clump giants in the Galactic bulge are approximate standard candles and hence they can be used as distance indicators. We compute the proper motion dispersions of RCG stars in the Galactic bulge using the proper motion catalogue from the second phase of the Optical Gravitational Microlensing Experiment (OGLE-II, Sumi et al. 2004) for 45 fields. The proper motion dispersions are measured to ...

Business Intelligence (BI) applications provide business information to drive decision support. Usability is one of the factors determining the optimal use and eventual benefit derived from BI applications. The documented need for more BI usability research together with the practical necessity for BI evaluation guidelines in the mining industry provides the rationale for this study. The purpos...

Software quality should be evaluated from different perspectives; we highlight the internal and external ones (ISO/IEC, 2002). Specially, internal quality evaluation depends on the software architecture (or design) and programming aspects rather than on the product behaviour. On the other hand, architectural evaluation methods tend to apply scenarios for assessing the architecture respect to qu...

Previous research has shown that acyclic dependency models, if they exist, can be extracted from software quality standards and that these models can be used to assess software safety and product quality. In the case of commercial off-the-shelf (COTS) software, the extracted dependency model can be used in a probabilistic Bayesian network context for COTS software evaluation. Furthermore, while...

The new challenge for designers and Human–computer interaction (HCI) researchers is to develop software tools and applications for effective e-learning. Software usability is one aspect of Human–computer interaction that can benefit from knowledge of the user and their tasks. However, in practice not much attention is given to this issue during testing. Evaluators often do not have the knowledg...

This paper proposes a modified software quality evaluation method based on products comparison, judging by user perceived satisfaction in terms of quality. The focused evaluation model is formulated on the bases of the ISO 9126 quality model as a generally accepted standard and ISO 12119 for software package, and of the Analytic Hierarchy Process (AHP) which is appropriate for comparing paired ...

Healthcare environments have always been considered an important scenario in which to apply new technologies to improve residents and employees conditions, solve problems and facilitate the performance of tasks. In this way, the use of sensors based on user movement interaction allows solving complicated situations that should be immediately addressed, such as controlling falls and fainting spe...

The increasing complexity of video game development highlights the need of design and evaluation methods for enhancing quality and reducing time and cost. In this context, Model-Driven Development approaches seem to be very promising since a video game can be obtained by transforming platformindependent models into platform-specific models that can be in turn transformed into code. Although thi...
