System analysis and development of information systems

Currently, career counselling services are offered in most of the higher education institutes in Saudi Arabia, however, there are no systems installed to automate these services. This paper takes Dar Al Hekma College (DAHC) in Saudi Arabia as motivation case and discusses the need of automating the college's counselling and career services. By following the stages of SDLC, an effective system was developed for a real-world environment. The methods used for fact finding techniques were observations, interviews, questionnaires, and discussions. The survey outcomes have also shown a positive reaction regarding the impact of installation of such a system. Insights from this study can be applied to other higher education institutes in Saudi Arabia.

The information systems analysis and design methodologies devised at the outbreak of the third industrial revolution shaped the systems analysis disciple and have trickled down to all systems influencing most aspects of human development. To cope with the explosion of digital technology, these methodologies had to be developed rapidly, drawing from a wide range of theoretical backgrounds, based mainly on the "hard" scientific method and the "softer" systems approach. In the run-up to industry 4.0, with multiple information systems emerging, reflection on systems' design fundamentals is important. Intended to serve human activity and well-being, information systems are anthropocentric. Their success lies in their ability to serve human goals. Information systems analysis and design methodologies play a role in this by ensuring the best match between what is sought from systems and what they deliver in terms of the systems' underlying final cause, or "telos". The paper investigates the teleological orientation of four founding systems analysis and design methodologies. Using the Wood-Harper and Fitzgerald taxonomy in order to identify the conceptual origins of the four methodologies under review, it categorizes and subsequently incorporates them in an extended taxonomy, assesses whether and how they are devised to cater to the incorporation of goals and explains the inferred results based on the taxonomy. The paper posits that the founding information systems analysis and design methodologies do not have a marked teleological orientation and do not dispose of techniques for adequately incorporating systems' goals.

Check Teck Foo discusses the interdisciplinary and holistic roots of Systems Engineering (SE) in the paper Systems Engineering Perspectives on the 2500-Year-Old Art of War by Sun Tzu. He identifies the importance of subsystems illustrations related to systems. He also highlights Sun Tzu’s prediction that performance is related to quantification. Foo finally parallels the Institute of Electrical and Electronics Engineers (IEEE) and International Council on Systems Engineering (INCOSE) seven facets of systems engineering as they compare to Sun Tzu’s work and the ASEAN region corporate strategy. We can begin to see Foo’s perspective on philosophical and systems thinking from the subsystems perspective related to Sun Tzu’s work.

Systems of systems exhibit characteristics that pose difficulty in modelling and predicting their overall performance capabilities, including the presence of operational independence, emergent behaviour, and evolutionary development. When considering systems of systems within the autonomous defence systems context, these aspects become increasingly critical, as constraints on the performance of the final system are typically driven by hard constraints on space, weight and power. System execution modelling languages and tools permit early prediction of the performance Communicated by Dr. Kai Sachs and Catalina Llado. of model-driven systems; however, the focus to date has been on understanding the performance of a model rather than determining whether it meets performance requirements, and only subsequently carrying out analysis to reveal the causes of any requirement violations. Moreover, such an analysis is even more difficult when applied to several systems cooperating to achieve a common goal-a system of systems. In this article, we propose an integrated approach to performance prediction of model-driven real-time embedded defence systems and systems of systems. Our architectural prototyping system supports a scenario-driven experimental platform for evaluating model suitability within a set of deployment and real-time performance constraints. We present an overview of our performance prediction system, demonstrating the integration of modelling, execution and performance analysis, and discuss a case study to illustrate our approach.

Using the descriptive and developmental design, the study developed and evaluated an eHealth application for women using decision tree classifiers. It focuses on the development of an eHealth application system using open-access datasets from UCI Machine Learning Repository. This attempts to predict the onset of diabetes and chronic kidney diseases grounding from the generated predictive models. These decision models are created using C4.5, ID3 and CART algorithms with RapidMiner data science platform. Performance metrics are deployed such as accuracy, recall, precision and error rate to compare the reliability of each model. Models incurred the highest assessment are the bases of the developed system following Agile Software Development Life Cycle Model. Easy access to healthcare workers through teleconsultation, diabetes and chronic kidney disease (CKD) online diagnosis, and maternal care videos are possible with this study. The summary of the evaluation showed that the eHealth Application got an overall average weighted mean of 3.98, which is described as high extent. Based on the respondents' response, the strongest point of the system was its portability, which earned the highest average mean among categories of system evaluation. Thus, the system addresses the shortcomings of healthcare in terms of distance and timeliness of treatment fostering an equal access to healthcare.

The purpose of this study is to know the library needs and to implement new library system for the development of the Dumaguete City Public Library.

The results of this study is to implement the new library system which can help the users to have a fast and easy access to the collections of the library. In conclusion the library need to change library system from traditional to digital format in order to cater the needs of the library users.

The increasing number of times that water was announced to be off at the National University of
Samoa (NUS) IHE1
campus during working hours has caused alarming concerns among staff and
students about a quality, healthy working environment at NUS. This situation originated an idea
amongst some of the academic staff of the Faculty of Science in NUS to approach this problem by
way of research. Six (6) research projects under the title – “Sustaining Healthy Quality
Environments – Ensuring Running Water Systems (SHQEERWaS) were proposed to: (i) look at
various ways with which may improve the situation at a higher education workplace, (ii) inform
development of quality working environment strategies at management level and (iii) find out the
perceptions of NUS campus occupants on the impacts of water outage during working hours at
NUS. This paper completes the suite of 6 research projects proposed. Its focus is on highlighting
the real and perceived impacts of water shortage during working hours on staff and students of
NUS IHE campus.

Technological innovation in a business organization becomes the trend in the 21st century. With more progress on hand, e-commerce has paved its way to the mainstream giving transformation opportunities such that in socioeconomic field. This paper presents the socioeconomic situation of a fisherfolk community in the province of Siquijor, Philippines and its development of a marine sanctuary park that created livelihood opportunities to the local fisherfolks in the area which led to the presence of Guiwanon Spring Park Resort. With close competition to other tourism-related establishments, the resort decided to adopt an e-commerce solution to keep abreast of technology innovation. Thus, the researcher creates an interactive mobile-ready application known as the GSPR e-Booking System which includes features that help the resort catch a wider market online. Further, creating conceptual foundations from existing practices, the author develops a new, integrated business transformation framework that helps explain how an e-commerce solution has generated a supplemental aid in the socioeconomic development of the said community. This framework is then presented to motivate other developing business communities to embrace more appropriate solution for issues brought by the current technological situation.

Elsewhere* we proposed a systemic methodological support for information systems development. One of our conclusions was about the importance of paralleling analysis and synthesis, and its internal detailed steps, which are usually executed serially in the traditional systematic methodologies, as in the case of "waterfall model". Parallelism and concurrence between analysis and synthesis, and among theirs detailed internal steps, make possible the existence of feedback and feedforward loops in order to achieve the flexibility required by the adaptability to a dynamic environment. But to manage an information system development project, requires milestones and, then, serial activities. Since analysis and synthesis (and theirs detailed internal steps) are not serial anymore in the framework we are proposing, they can support no milestones for project management. Consequently we are proposing a paradigmatic shift for milestones identification, based on a Conjoined Co-Evolutive Incremental Methodology. Instead of serializing analysis and synthesis, we propose to serialize effectiveness and efficiency, and their respective internal detailed activities, which will be given in the paper. We will find these internals activities by crossing fundamental dichotomies, such as thinking/acting, external /internal, feedback/feedforward, etc. As a result, we will have seven activities oriented toward achieving effectiveness, and seven oriented to achieving adequate efficiency.

In this paper we will try to show that the software crisis is effectiveness, not an efficiency one as it is assumed, explicitly or implicitly, by most authors, practitioners and methodologists. Indeed, some efficiency problems are rooted at a lack of effectiveness. Solutions to both kinds of problems are not necessarily the same. On the contrary: in a dynamic context one kind of solution could oppose the other. Consequently, conceptual differentiation between both kinds of problems should explicitly be done by methodologists, while designing software development methodologies, and by practitioners and projects managers, while planning and controlling information systems development projects. Efficiency orientations are supported by positivistic epistemologies, which were identified by Livari* as the kernel of present methodologies. We present a general guideline for an effectiveness orientation based on a non-positivistic epistemology. Then, we will differentiate between systematic and systemic methodologies being the firsts associated with efficiency orientation, and the seconds, with an effectiveness one.
