Quality improvement through the identification of controllable and uncontrollable factors in software development

The software engineering community has moved from corrective methods to preventive methods shifting the emphasis from product quality improvement to process quality improvement. Inspections at the end of the production line have been replaced by design walkthroughs and built-in quality assurance techniques throughout the development lifecycle. Process models such as the Spiral, V, W and X-Models provide the principles and techniques for process improvement which, in turn, produces product improvement. Factors that affect the quality of software need to be identified and controlled to ensure predictable and measurable software. In this paper we identify controllable and uncontrollable factors and provide empirical results from a large industrial survey, as well as conclusions relating to the models and metamodels for the estimation, measurement and control of the totality of features and characteristics of software

Ethical issues invoked by Industry 4.0

Industry 4.0 is universally referred to as the fourth industrial revolution. It is a current trend of automation and data exchange in manufacturing technologies. The computerisation of manufacturing includes, amongst other, cyber-physical systems, the Internet of Things (IoT), cloud computing and cognitive computing. There are many challenges in the realisation of Industry 4.0. In order to adopt a "smart factory" and improved (software) processes many ethical considerations need to be identified and considered if a company is to obtain an ethical development and deployment of Industry 4.0. The purpose of normative ethics is to scrutinise standards about the rightness and wrongness of actions, the ultimate goal being the identification of the true human good. A rational appeal can be made to normative defensible ethical rules in order to arrive at a judicious, ethically justifiable judgement. In this position and constructive design research paper our steps are: First we report on the findings of a broad literature review of related research, which refers to the current challenges in the realisation of Industry 4.0. Second, we identify and list some basic generic Deontological and Teleological ethical principles and theories that can serve as normative guidelines for addressing the challenges identified in the initial step. Third, we prescribe a set of ethical rights and duties that must be exercised and fulfilled by protagonists/stakeholders in Industry 4.0 implementation in order for them to exhibit ethical behaviour. Each of these suggested actions are substantiated via an appeal to one, or a number of the normative guidelines, identified in the second step. By identifying and recommending a set of defensible ethical obligations that must be fulfilled in the development and deployment of smart factories, protagonists such as: employers, project managers, technology suppliers, trade unions, (on a microscopic level) and chambers of commerce, local and national government (on a macroscopic level) and other can fulfil their ethical duties. Thus, a deployed Industry 4.0 solution can result in technological change, social change and changes in the business paradigm, which are all ethically justifiable. Ultimately all the improvement processes of Industry 4.0 implementation must be underpinned with ethical consideration

The sociocultural dimension of the Software Process Improvement manifesto: pilot validation by experts

The SPI Manifesto is based on three basic values: people, business focus, and organizational change underpinning the philosophy of Software Process Improvement (SPI). In turn, these values bring up to date certain SPI principles serving as a foundation for action in software development. The authors of this paper carried out a pilot expert validation of the Sociocultural dimension of the STEEPLED (Sociocultural, Technical, Economic, Environmental, Political, Legal, Ethical and Demographic) analysis of the SPI Manifesto. Further, the authors report on the rationale and results of the pilot validation of both the survey instrument and the qualitative responses generated by the field experts, targeting to enlighten and reinforce the importance of the Sociocultural dimension of the SPI Manifesto in research and development. The related literature review findings and the pilot research study strengthen this target. The pilot study with experts in particular provided stronger indications that the Sociocultural dimension is considered of high importance by between 62% and 88% of the respondents, who were IT and Computing professionals and software practitioners from academia and industry

Towards a multidimensional self-assessment for software process improvement: a pilot tool

The SPI Manifesto provides a framework for guiding software development organisations in their improvement efforts. Based on the Values of People, Business and Change, which are supported and informed by one or more of the ten principles, the designer and developer can avoid pitfalls, minimise risks and make their business successful. It has been established, in theory and practice, that improving the process results in improvement of the products and services emanating from that process. Following a number of earlier multidimensional analyses of the SPI Manifesto, carried out by the authors, a series of tabular representations identifying the nature, importance and strength of relationships between the Manifesto’s Values and Principles in terms of eight dimensions encapsulated in the acronym STEEPLED (Sociocultural, Technical, Economic, Environmental, Political, Legal, Ethical and Demographic) were developed. In this paper, we present a conceptualisation of a pilot automated tool (based on the STEEPLED Analysis), which could, potentially, be implemented/realised and used for self-assessment by software developing organisations. Starting with a self-assessment, current issues and requirements could be identified and revealed. The self-assessment using the pilot automated tool would, additionally, reveal areas requiring improvement, and would serve as a guide for the participating organisation to put focus on prioritising candidate process areas that require improvement. Also, the field testing of the pilot tool could enable the design and improvement of the tool itself, which, in turn, will be used in future for expert external/independent process assessment

Impact of the Covid-19 pandemic on education: experiences and feelings reported by primary school pupils from Greece and Turkey

Covid 19 pandemic had a huge impact upon life and the educational experience of students. One of the groups mostly affected from this pandemic is the school children. The sudden transition to distance education from traditional face-to-face education undoubtedly changed the implementation methods of the teaching programme in schools. The research study reported in this paper was carried out in Greece and Turkey. Responses were collected from primary school pupils who voluntarily and anonymously completed an online questionnaire with multiple choice questions. The latter were carefully worded in an appropriate and understandable way, using language suitable for primary school aged children. Comparisons between the responses from the two countries revealed similarities and differences. Through a comparative approach the research results are particularly scruitinised through the lenses of equal opportunities and social exclusion policies along with a cross cultural perspective, which is expected to have a useful impact during the post pandemic era. By sharing the collective knowledge and experience gained, we aspire to propose educational strategies for well-being and recovery, and overall educational process improvement

The impact of the COVID-19 pandemic on the learning and wellbeing of secondary school students: a survey in Southern Europe

The transition from the traditional model of learning and teaching to full online mode had to be implemented in many countries, in an extremely short time, as the 2020-2021 school year was in mid-stream. Secondary education, which includes students in the age range of 12-18, faced many challenges in this rapid change, as many research studies have shown. Researchers raise questions regarding the readiness of the secondary education community to transition to fully online learning. The pilot study reported in this paper deals with the impact of the transition to online learning on secondary schools in southern European countries. More specifically, this paper presents the results of a literature survey and an empirical survey using an online questionnaire which captured non-traceable responses from secondary schools that, voluntarily and anonymously, completed the questionnaire. The questions were mainly closed, with some open-ended questions for students to fill in. The study also aims to capture data on the socio-economic dimension, accessibility/ availability of the necessary technologies that enable online learning, as well as the families’ employment status and their ability to support students. A total of 90 students participated (62% female, 28% male) from three Mediterranean countries. The students’ perspectives as seen by the students themselves along with the difficulties and the issues they faced are compared and contrasted. This investigation offers a pedagogical and socio-technical analysis and highlights the needs for wellbeing as well as quality learning and teaching in the new social distance reality

Preferences of Hungarian consumers for quality, access and price attributes of health care services — result of a discrete choice experiment

In 2010, a household survey was carried out in Hungary among 1037 respondents to study consumer preferences and willingness to pay for health care services. In this paper, we use the data from the discrete choice experiments included in the survey, to elicit the preferences of health care consumers about the choice of health care providers. Regression analysis is used to estimate the effect of the improvement of service attributes (quality, access, and price) on patients’ choice, as well as the differences among the socio-demographic groups. We also estimate the marginal willingness to pay for the improvement in attribute levels by calculating marginal rates of substitution. The results show that respondents from a village or the capital, with low education and bad health status are more driven by the changes in the price attribute when choosing between health care providers. Respondents value the good skills and reputation of the physician and the attitude of the personnel most, followed by modern equipment and maintenance of the office/hospital. Access attributes (travelling and waiting time) are less important. The method of discrete choice experiment is useful to reveal patients’ preferences, and might support the development of an evidence-based and sustainable health policy on patient payments
