A document based traceability model for test management

Software testing has became more complicated in the emergence of distributed network, real-time environment, third party software enablers and the need to test system at multiple integration levels. These scenarios have created more concern over the quality of software testing. The quality of software has been deteriorating due to inefficient and ineffective testing activities. One of the main flaws is due to ineffective use of test management to manage software documentations. In documentations, it is difficult to detect and trace bugs in some related documents of which traceability is the major concern. Currently, various studies have been conducted on test management, however very few have focused on document traceability in particular to support the error propagation with respect to documentation. The objective of this thesis is to develop a new traceability model that integrates software engineering documents to support test management. The artefacts refer to requirements, design, source code, test description and test result. The proposed model managed to tackle software traceability in both forward and backward propagations by implementing multi-bidirectional pointer. This platform enabled the test manager to navigate and capture a set of related artefacts to support test management process. A new prototype was developed to facilitate observation of software traceability on all related artefacts across the entire documentation lifecycle. The proposed model was then applied to a case study of a finished software development project with a complete set of software documents called the On-Board Automobile (OBA). The proposed model was evaluated qualitatively and quantitatively using the feature analysis, precision and recall, and expert validation. The evaluation results proved that the proposed model and its prototype were justified and significant to support test management

Using a Socio-Technical Model of a Global Software Development Project for Facilitating Risk Management and Improving the Project Structure

Any global software development project needs to deal with distances – geographical, cultural, time zone, etc. – between the groups of developers engaged in the project. To successfully manage the risks caused by such distances, there is a need to explicate and present the distances in a form suitable for manual or semi-automatic analysis, the goal of which is to detect potential risks and find ways of mitigating them. The article presents a technique of modeling a global software development project suitable for such analysis. The project is modeled as a complex socio-technical system that consists of functional components connected to each other through output-input relationships. The components do not coincide with the organizational units of the project, and their teams can be distributed through the geographical and organizational landscape of the project. The modeling technique helps to explicate and represent various kinds of distances between the functional components to determine which of them constitute risk factors. The technique was developed during two case studies, of which the second is used for presenting and demonstrating the new modeling technique in the article

Computational Intelligence and Human- Computer Interaction: Modern Methods and Applications

The present book contains all of the articles that were accepted and published in the Special Issue of MDPI’s journal Mathematics titled "Computational Intelligence and Human–Computer Interaction: Modern Methods and Applications". This Special Issue covered a wide range of topics connected to the theory and application of different computational intelligence techniques to the domain of human–computer interaction, such as automatic speech recognition, speech processing and analysis, virtual reality, emotion-aware applications, digital storytelling, natural language processing, smart cars and devices, and online learning. We hope that this book will be interesting and useful for those working in various areas of artificial intelligence, human–computer interaction, and software engineering as well as for those who are interested in how these domains are connected in real-life situations

PBL Student Projects and Sustainable Development Goals: A Case Study

Working with the Sustainable Development Goals can be a highly motivating factor in Problem Based Learning, especially if the solutions produced can be used afterwards and have an actual impact on people and communities. This paper describes how three engineering students from Aalborg University, Denmark, collaborated with the South African Organisation Green Shoots on bringing IT-supported Math education out to some of the most disadvantaged learners from townships and rural areas of the Western Cape. The project provided the Danish students with a unique learning experience and have a lasting impact on the communities involved. While the content of the project focused on bringing IT-supported Math education to learners in previously disadvantaged areas around the Western Cape, the project also provided valuable insight into how such students’ projects, where the outcomes benefit people and communities suffering from socio-economic challenges e.g. poverty, can be carried out. In addition to demonstrate that such projects are actually possible, we studied three critical aspects: How to ensure a good fit between learning objectives and project outcome, how to ensure that the project creates value for the partner organisation and communities, and how to ensure that the projects can be conducted without overloading the university supervisors. We believe that student projects focusing on SDGs have a big potential in terms of providing highly motivating student projects yet at the same time contribute to a better world through solutions that are being used even afterwards. However, our study was just a single case with one group of three students. We hope it will serve as inspiration for larger studies, where more quantitative data could be gathered in terms of how to establish a good framework around such projects, and in order to demonstrate the value for students and societies

International Student Projects and Sustainable Development Goals: A Perfect Match

Engineering Education is currently going through a transformation, driven by the need for educating better engineers and more engineers, and largely build on elements such as problem orientation, interdisciplinarity, internationalization, digitalization and sustainability. In 2020, the Erasmus+ Strategic Partnership EPIC (Improving Employability Through Internationalization and Collaboration) has combined all these elements, and demonstrated how international and interdisciplinary student projects, focusing on solving real-world problems related to sustainability, can be carried out in a setting where students mainly work together online. A total of 56 students from 7 EU and 2 international universities, with backgrounds ranging from Electrical Engineering and Mechanical Engineering to Textile Technologies and Business Informatics were working on 9 different projects throughout the spring of 2020. The paper presents the experiences from the setup and discusses some general recommendations for setting up this type of projects. The paper goes through the stages of defining and carrying out the projects: Defining the overall framework, identifying problems/project proposals in collaboration with relevant stakeholders, identifying the students and assigning students to projects, preparing students and supervisors, organising the physical kick-off seminar, and supporting the online collaboration. We also discuss evaluation and hand-over of the solutions, to ensure the projects have a lasting impact. We conclude that the sustainable development goals provide a highly motivating framework for interdisciplinary, international student projects based on problem-based learning. We also note that a careful design and execution of the all the preparatory stages are crucial in order for the projects to succeed, and discuss specific recommendations for these.</p

An evaluation of the challenges of Multilingualism in Data Warehouse development

In this paper we discuss Business Intelligence and define what is meant by support for Multilingualism in a Business Intelligence reporting context. We identify support for Multilingualism as a challenging issue which has implications for data warehouse design and reporting performance. Data warehouses are a core component of most Business Intelligence systems and the star schema is the approach most widely used to develop data warehouses and dimensional Data Marts. We discuss the way in which Multilingualism can be supported in the Star Schema and identify that current approaches have serious limitations which include data redundancy and data manipulation, performance and maintenance issues. We propose a new approach to enable the optimal application of multilingualism in Business Intelligence. The proposed approach was found to produce satisfactory results when used in a proof-of-concept environment. Future work will include testing the approach in an enterprise environmen

Factors Influencing Customer Satisfaction towards E-shopping in Malaysia

Online shopping or e-shopping has changed the world of business and quite a few people have decided to work with these features. What their primary concerns precisely and the responses from the globalisation are the competency of incorporation while doing their businesses. E-shopping has also increased substantially in Malaysia in recent years. The rapid increase in the e-commerce industry in Malaysia has created the demand to emphasize on how to increase customer satisfaction while operating in the e-retailing environment. It is very important that customers are satisfied with the website, or else, they would not return. Therefore, a crucial fact to look into is that companies must ensure that their customers are satisfied with their purchases that are really essential from the ecommerce’s point of view. With is in mind, this study aimed at investigating customer satisfaction towards e-shopping in Malaysia. A total of 400 questionnaires were distributed among students randomly selected from various public and private universities located within Klang valley area. Total 369 questionnaires were returned, out of which 341 questionnaires were found usable for further analysis. Finally, SEM was employed to test the hypotheses. This study found that customer satisfaction towards e-shopping in Malaysia is to a great extent influenced by ease of use, trust, design of the website, online security and e-service quality. Finally, recommendations and future study direction is provided. Keywords: E-shopping, Customer satisfaction, Trust, Online security, E-service quality, Malaysia
