A Generalized approach to the operationalization of Software Quality Models

Comprehensive measures of quality are a research imperative, yet the development of software quality models is a wicked problem. Definitive solutions do not exist and quality is subjective at its most abstract. Definitional measures of quality are contingent on a domain, and even within a domain, the choice of representative characteristics to decompose quality is subjective. Thus, the operationalization of quality models brings even more challenges. A promising approach to quality modeling is the use of hierarchies to represent characteristics, where lower levels of the hierarchy represent concepts closer to real-world observations. Building upon prior hierarchical modeling approaches, we developed the Platform for Investigative software Quality Understanding and Evaluation (PIQUE). PIQUE surmounts several quality modeling challenges because it allows modelers to instantiate abstract hierarchical models in any domain by leveraging organizational tools tailored to their specific contexts. Here, we introduce PIQUE; exemplify its utility with two practical use cases; address challenges associated with parameterizing a PIQUE model; and describe algorithmic techniques that tackle normalization, aggregation, and interpolation of measurements.

Research on Enhancement Strategies for the Integration of Industry-Education Information Technology Platforms in Vocational Colleges

During this pivotal period in which China's vocational education is transitioning from a scale-oriented to a connotation-oriented development, efforts to reform vocational education are continuously intensifying, with the integration of industry and education consistently serving as the key logical thread in the reform of the modern vocational education system. Educational informatization stands as a crucial indicator of educational modernization, and the comprehensive promotion of educational modernization through educational informatization is a significant strategic decision for China's educational reform and development. However, integration of industry and education has not formed mutual integration and commonality between the entire school and enterprise levels in aspects such as talent cultivation, faculty construction, and scientific research cooperation, leading to a lack of a scientific evaluation system for assessing the effectiveness of this integration. Therefore, vocational colleges should actively construct an integration of industry and education information management platform based on the thinking of integration of industry and education and the ISO 25010 software quality model. This will further improve and enhance the service capabilities of the integration of industry and education information technology platform, facilitate multi-party interactive cooperation among governments, industries, enterprises, and schools, better meet the requirements of talent cultivation model transformation and innovative development in the construction of higher vocational colleges, and standardize the process of integration of industry and education, making it more transparent, visualizing data analysis, and comprehensively evaluating effectiveness.

Bridging the Gap Between Universities and Alumni: A User-Centered Evaluation of a Digital Alumni Engagement Platform

Universities face an ongoing challenge in fostering meaningful connections with their alumni communities. This paper presents the development and evaluation of the Alumni Tracer and Engagement Hub, a web-based platform designed to bridge the gap between universities and their alumni. The study employed a comprehensive approach, utilizing McCall's Software Quality Model for technical evaluation during the development and testing phases. Following deployment, a user-centric evaluation assessed the platform's effectiveness in achieving its objectives. This evaluation leveraged the ISO/IEC 25010 model and gathered feedback through surveys and interviews with alumni, administrators, and staff. The evaluation results revealed a strong technical foundation, with high marks for security, self-documentation, code clarity, and user-friendliness (McCall's model). User feedback (ISO/IEC 25010 model) indicated positive experiences with core functionalities like functional completeness, performance, and learnability. However, areas for improvement were identified in the user interface aesthetics, clarity of element purpose, and user perceptions of data security. This paper discusses these findings and proposes recommendations for optimizing the platform's user experience, strengthening data security measures, and ensuring long-term technical maintainability. By implementing these recommendations, the Alumni Tracer and Engagement Hub has the potential to become a valuable tool for universities to strengthen alumni connections and build a thriving alumni network.

Quality Control Methods Using Quality Characteristics in Development and Operations

Since the Software Quality Model was defined as an international standard, many quality assurance teams have used this quality model in a waterfall model for software development and quality control. As more software is delivered as a cloud service, various methodologies have been created with an awareness of the link between development productivity and operations, enabling faster development. However, most development methods are development-oriented with awareness of development progress, and there has been little consideration of methods that achieve quality orientation for continuous quality improvement and monitoring. Therefore, we developed a method to visualize the progress of software quality during development by defining quality goals in the project charter using the quality model defined in international standards, classifying each test by quality characteristics, and clarifying the quality ensured by each test. This was achieved by classifying each test by quality characteristics and clarifying the quality ensured by each test. To use quality characteristics as KPIs, it is necessary to manage test results for each test type and compare them with past build results. This paper explains how to visualize the quality to be assured and the benefits of using quality characteristics as KPIs and proposes a method to achieve rapid and high-quality product development.

A study of behavioral decay in design patterns

AbstractDesign patterns represent a means of communicating reusable solutions to common problems, provided they are implemented and maintained correctly. However, many design pattern instances erode as they age, sacrificing qualities they once provided. Identifying such instances of pattern decay is valuable because it allows for proactive attempts to extend the longevity and quality attributes of pattern components. Apart from structural decay, design patterns can exhibit symptoms of behavioral decay. We utilized a taxonomy that characterizes these negative behaviors and designed a case study wherein we measured structural and behavioral decay, hereafter referred to as pattern grime, as well as pattern quality and size, across pattern evolutions. We evaluated the relationships between structural and behavioral grime and found statistically significant cases of strong correlations between specific types of structural and behavioral grime. Furthermore, we extended the QATCH operational software quality model to incorporate design pattern evolution metrics and measured and correlated software quality to the presence of behavioral grime in software systems. Our results suggest a strong inverse relationship between software quality and behavioral grime.

PE-M: Prediction of malnutrition of Barangay 35 Tondo Manila using random forest algorithm

Malnutrition is still an ongoing problem in the Philippines as it poses a threat especially to children. There are multiple considerations for malnutrition in order to help find the root cause of malnutrition for each child, it is quite a tedious task to perform. According to the classification of undernutrition rates, the prevalence in the Philippines is of "extremely high" public health relevance. It was stated that in 2019, the prevalence of underweight and wasting was 19% and 6%, respectively. Poverty amplifies the risk of, and risks from, malnutrition. People who are poor are more likely to be affected by different forms of malnutrition. Also, malnutrition increases health care costs, reduces productivity, and slows economic growth, which can perpetuate a cycle of poverty and ill-health. The application Pe-M, is a web application which is aimed to predict the malnutrition rate within Barangay 35 in Tondo Manila City and also give food recommendations based on the classification the children are categorized. The application uses Random Forest Algorithm in calculating the prediction from the data provided in order to calculate the percentage of malnutrition present in Barangay 35 Tondo Manila City. To ensure that the web application performs as per its specified requirements, a comprehensive specification and evaluation of software product quality was conducted using the ISO 25010 software quality model. This study specifically seeks to evaluate the web application in terms of performance efficiency and usability. The following results show that there are kids that fall in the classification of malnutrition showing that there is malnutrition in the barangay. The confusion matrix shows that RFA gives 87.80% accuracy based on the risk factors given and the trained data in the system. The RFA predicted that 21.95% of the data is said to be the malnutrition rate in the barangay based on the given data and the highest risk factor in the data with 3.6% is mineral water consumption of the citizens. The model identified the risk factors which helped predict malnutrition rate making the model more reliable and transparent.

A Quality Model-based Approach for Measuring User Interface Aesthetics with Grace

User interface aesthetics, a particular sub-characteristic of the ISO 25010 software quality model, is correlated to the perceived or actual usability of a graphical user interface, its user experience, and trust. While many measures, such as balance, symmetry, proportion, alignment, regularity, and simplicity, can be computed, no consensus exists today on which measure to adopt, which formula to compute for each measure, and which interpretation to give for each computed formula. To accommodate these variations and to make the assessment explicit and interpretable, we present a quality model-based approach for measuring aesthetics that defines a quality function in terms of the formula of the measures, their weights, their composition, and their overall computation. This quality model is transformed into a configuration used by GRACE, a web application developed for this purpose. When the measures, their formula, their weights, or the quality function change, the quality model changes, which is re-computed to compare it with any other model, thus making the measurement process explicit and interpretable. We apply this approach to a large dataset "Lab in the Wild'' to investigate the correlations between aesthetic measures and perceived visual complexity and colorfulness. We discuss limitations through threats to validity.

Framework for selecting the best software quality model for a smart health application based on intelligent approach

There is difficulty in knowing how to weigh the factors of software quality models so that decision-making can be eased. Furthermore, previous work was limited to undertake evaluation and selection of appropriate software quality model based upon multi-criteria in the context of smart health applications. This paper aims to evaluate and select an appropriate model of software quality based on multi-criteria decision-making (MCDM) by three phases of framework. Firstly, investigation of software quality models and factors that were identified based on ‘fuzzy delphi’. Secondly, identification of quality models that have uniform multi-criteria so that a decision matrix could be established. Uniform multi-criteria were used in the decision matrix as the basis of the models of quality and the multi-criteria. Subsequently, MCDM approach is adopted and the bases used in the employment of the MCDM approach for the eva luation and selection of the software quality model were technique for order preference by similarity to ideal solution (TOPSIS) and fuzzy analytical hierarchy process (FAHP). The results demonstrated that seven quality factors could be considered as the key factors based upon fuzzy delphi, i.e., usability, maintainability, reliability, interoperability, portability, modifiability, and efficiency. Also, reults shows that McCall is the most appropriate model.
