Practical Consequences of Quality Views in Assessing Software Quality

The authors’ previously published research delved into the theory of software product quality modelling, model views, concepts, and terminologies. They also analysed this specific field from the point of view of uncertainty, and possible descriptions based on fuzzy set theory and fuzzy logic. Laying a theoretical foundation was necessary; however, software professionals need a more tangible and practical approach for their everyday work. Consequently, the authors devote this paper to filling in this gap; it aims to illustrate how to interpret and utilise the previous findings, including the established taxonomy of the software product quality models. The developed fuzzy model’s simplification is also presented with a Generalized Additive Model approximation. The paper does not require any formal knowledge of uncertainty computations and reasoning under uncertainty, nor does it need a deep understanding of quality modelling in terms of terminology, concepts, and meta-models, which were necessary to prepare the taxonomy and relevance ranking. The paper investigates how to determine the validity of statements based on a given software product quality model; moreover, it considers how to tailor and adjust quality models to the particular project’s needs. The paper also describes how to apply different software product quality models for different quality views to take advantage of the automation potential offered for the measurement and assessment of source code quality. Furthermore, frequent pitfalls are illustrated with their corresponding resolutions, including an unmeasured quality property that is found to be important and needs to be included in the measurement and assessment process.

Software Product Quality Models, Developments, Trends, and Evaluation

Software product quality models have evolved in their abilities to capture and describe the abstract notion of software quality since the 1970s. Many models constructed deal with a specific part of software quality only which makes them ineligible to assess the quality of software products as a whole. Former publications failed to thoroughly examine and list all the available models which attempt to describe each known property of software product quality. This paper discovers such complete software product quality models published since 2000; moreover, it endeavours to measure the relevance of each model quantitatively by introducing indicators with regard to the scientific and industrial community. The identified 23 software product quality model classes differ significantly in terms of publication intensity, publication range, quality score average, relevance score and the 12-month average of the Google Relative Search Index. The results offer a foundation for selecting the appropriate software product quality model for use or for extension if newly identified quality properties need to be connected to a general context. Furthermore, the experiences accumulated on the field of software product quality modelling motivated researchers to successfully transfer the concepts to other areas where abstract entities need to be compared or assessed including the quality of higher educational teaching and business processes, which is also briefly highlighted in the paper.

A Customized Grade Evaluation and Student Retention System (GESRS) for a Philippine State University

Objectives: This study focused on the development of a Customized Grade Evaluation and Student Retention System (GESRS) for Eastern Samar State University, a state university located in Eastern Samar, Philippines. The major functions of the system are (a) monitoring of student’s retention status and (b) evaluation of student’s grade. Methods/Statistical Analysis: This study adapted the Developmental – Evaluative research design. The researcher developed a system using the Iterative Development Model. The system was evaluated using two (2) sets of questionnaires. The first questionnaire adopted metrics from the ISO 9126 Software Product Quality Model. The second questionnaire used the IBM Computer Usability Satisfaction Scale. Findings: After the rigorous development, the researcher was able to incorporate the following restores into the system: (a) Student grade evaluation with student retention (b) reports generation of students with student retention status (c) grade adding, uploading and updating module for instructors. The expert testing resulted to a mean of4.50 for reliability, 4.68 for usability, 4.73 for efficiency, 4.60 for maintainability, and 4.64 for portability, all were interpreted as highly functional, highly reliable, highly usable, highly efficient, highly maintainable and highly portable respectively. This means that the system was free from errors, easy to use, has proper data management and can be transported from one computer system to another easily. The End-user testing recorded a high rating for question 6, 1, and 2 respectively. This only means that the end-users found the system easy to use, was satisfied with the over-all look of the system and found the simple button and module orientation of the system easy to navigate. It was also evident in the results that they were able to finish their tasks using the system. Application and Improvements: The successful development of the system will pave way to the successful implementation of the retention policy of the university and will further enhance the monitoring of student grades and retention status. Keywords: Automation, Information System, Retention, Student Evaluation, Student Grade

A Framework for Evaluating the Software Product Quality of Pregnancy Monitoring Mobile Personal Health Records.

Stakeholders' needs and expectations are identified by means of software quality requirements, which have an impact on software product quality. In this paper, we present a set of requirements for mobile personal health records (mPHRs) for pregnancy monitoring, which have been extracted from literature and existing mobile apps on the market. We also use the ISO/IEC 25030 standard to suggest the requirements that should be considered during the quality evaluation of these mPHRs. We then go on to design a checklist in which we contrast the mPHRs for pregnancy monitoring requirements with software product quality characteristics and sub-characteristics in order to calculate the impact of these requirements on software product quality, using the ISO/IEC 25010 software product quality standard. The results obtained show that the requirements related to the user's actions and the app's features have the most impact on the external sub-characteristics of the software product quality model. The only sub-characteristic affected by all the requirements is Appropriateness of Functional suitability. The characteristic Operability is affected by 95% of the requirements while the lowest degrees of impact were identified for Compatibility (15%) and Transferability (6%). Lastly, the degrees of the impact of the mPHRs for pregnancy monitoring requirements are discussed in order to provide appropriate recommendations for the developers and stakeholders of mPHRs for pregnancy monitoring.

An evaluation of the quality of management information systems used by SACCOs in Kenya

Purpose – Savings and Credit Cooperatives (SACCOs) in developing countries require core banking Management Information Systems (MISs) to run their business, serve their clients and provide differentiated products and services to gain competitive advantage. Considering that SACCOs in Kenya lack the necessary resources to acquire the best information systems, the purpose of this paper is to evaluate MISs currently in use in the SACCO subsector to determine how well they are serving. Design/methodology/approach – Using the ISO/IEC 25010 Software Product Quality Model, the quality of MISs operated by 215 Deposit-Taking SACCOs in the Kenya was evaluated to determine their level of performance. Findings – The results indicated that the MISs currently in use by the SACCOs serve them well in terms of functionality, efficiency, reliability, ease of use and portability. However, vendor support, technical training and implementation process are a big concern to the SACCOs. Practical implications – The SACCOs in Kenya need not look for other MISs as the ones in use satisfied the condition required by the ISO/IEC 25010 Software Product Quality Model. The areas that require attention are vendor support services by entering into contracts technical training and service level agreement; and good project management in software implementation. Originality/value – The research addresses itself to one of the biggest setbacks faced by a fast growing subsector in adopting ICT with limited capacity and infrastructure.

Establishing software product quality requirements according to international standards

Software product quality is an important concern in the computer environment and whose immediate results are appreciated in all the activities where computers are used. The ISO/IEC 9126 standard series settle a software product quality model, for example, in the annex, shows the identification of the quality requirements like a necessary step for product quality. However, the standard does not included the way to get quality requirements, neither how to establish metrics levels. Establishing quality requirements and metric levels seems to be simple activities but they could be annoying and prone to errors if there is not a systematic approach for the process. This article presents a proposal for establishing product quality requirements according to the ISO/IEC 9126 standard.
