In: Proceedings of the 53nd Hawaii International Conference on System Sciences. Hawaii, USA 2020. doi:10.24251/HICSS.2020.452 Citation Details

    Self-tracking solutions have become globally widespread, as they promise numerous advantages (e.g. improving health) to their users. Despite their benefits, such solutions are often abandoned due to quality issues. This phenomenon can also be observed for digitized products in general. As self-tracking solutions are hybrid products, combining digital and physical components, traditional domain-independent and abstract quality models like the prominent ISO 25000 standard seem to not cover quality in an appropriate way. We address these issues by answering the research question of which factors affect quality perceptions of different stakeholder groups when interacting in a wearable ecosystem. We use a systematic literature review based on a research protocol to identify and analyze 98 quality-influencing factors from 19 studies that we cluster in a map. The identified factors are compared to the ISO 25000 standard, showing that certain factors like hedonic motivation are unconsidered thoroughly in the existing standard.

    Smart connected products (SCPs) have gained significant attention in different domains because they offer numerous benefits and change the way of competition and value creation. While quality is im-portant for SCPs, no holistic quality model is available to target the present quality problems. Further-more, since the concept of an SCP is quite abstract, a bottom-up approach that starts with a concrete example seems suitable. Therefore, this paper identifies the five key components of SCPs and maps them to self-tracking solutions (STS) in order to show that STSs are suitable substitutes. We also analyse quality models in corresponding areas to verify the absence of a holistic quality model for the selected example. This contribution identifies the research gap regarding holistic, stakeholder-oriented quality models and helps researchers understand SCPs better.

    Today, value is co-created in sociotechnical systems in which different stakeholders integrate resources (products and services) in an interactive process. For these systems to be successful, quality is very important. However, existing systems often fail to deliver the right level of quality, and the available quality approaches seem to be insufficient. Therefore, this paper provides insight into the role of quality by applying a service system perspective. We show that a holistic quality perception that reflects the modern expectations of stakeholders is necessary. In addition, different resources for modern services and their interaction need to be taken into account. This results in the need for quality management specific for sociotechnical systems, which integrates different existing approaches to cover these demands. Furthermore, the authors suggest future research on perceived quality and technical support in this context.

    1. EXECUTIVE SUMMARY

    This paper discusses the use of existing and new microformats for semantic injection of institutional websites in order to make their valuable information more accessible to students – directly via client tools or indirectly via information portals.

    1.1. Background

    The Bologna process increased the demand for information on degree programmes. The Faculty of Business Administration and Economics at University of Duisburg-Essen uses two higher-educationspecific content management solutions to satisfy this (and other) information demands by web-based course catalogues.

    Thanks to pan-European standardized degrees students may face a wide market for degree programmes. In the best case institutional websites present detailed information on degree programmes and related information in an intuitive way. Of course additional effort is necessary to compare different universities, their academics and degrees due to a lack of consistency and homogeneity.

    Microformats as a semantic technology enable the markup of existing websites and thus create semantically rich information. Since the two systems at the Faculty of Business Administration and economics are template based, inserting microformats seems an easily applicable solution – suitable microformats assumed.

    1.2. Focus

    After discussing the problem statement and introducing the concept of microformats the paper firstly presents the analysis of existing microformats for the given scenario. Secondly Metadata for Learning Opportunities (MLO) is reviewed as a possible blueprint for the semantic structure of course information to design new microformats for higher education. Thirdly scenarios for the future usage of these microformats in form of new application concepts for access of course related information are presented: web browser add-ons understanding the semantic, client tools retrieving the embedded semantic without the indirection via a web browser (e.g. a course catalogue reader for smart phones) and information portals retrieving semantically enhanced information of institutional websites from different universities for comparing their degree programmes.

    1.3. Conclusion

    This paper closes with a reflection of the approach, the current state of the analysis, possible alternatives and open work items.<span id="1252314128046S"> <span id="1252314278278S"> </span>

    1.   EXECUTIVE SUMMARY

    This paper addresses the problems in information management on modularized courses in an interdisciplinary working department. After this, the general system design goals of bolognaT3 are introduced, which is a web based, centralized system for the management of course catalogues at the Faculty of Business Administration and Economics at the University of Duisburg-Essen. The success factors of the system and the rollout-project conclude the article.

    1.1.   Background

    Universities in Europe and especially in Germany are facing new conditions due to the Bologna process and the introduction of tuition fees. The Bologna process – intending to make the degrees of universities comparable – requires new structures for study programmes. The introduction of tuition fees – intending to lift the quality of the education by financing a portion of the costs through students – makes students to customers. The first causes a higher need for information guiding students and staff to the new way of studying. The second causes students to request better services and correct information anywhere and anytime. The competition between universities in Europe is hereby no longer only about reputation and academics but also on student service and the use of modern information technologies.

    The design of study programmes and academics in German universities are under decentralise control of the departments. The need to create new study courses and to change the structure and content of existing ones results in a high information demand by the committees responsible. The necessary information is often neither available in a central system nor in a formal matter. Often enough some of the information is hidden inside exam regulations at the exam office or inside the content of a lecture.

    Once the information is collected it is seldom kept up to date, because there is no possibility to easily look up which information is used where. Especially in departments with interdisciplinary courses which make use of the exchangeability of course modules there is a need to overcome problems of redundancy and out-dated information.

    1.2.   Conclusions

    Existing university systems and processes did not fit the need for structured information and information reuse on the one hand and detailed and configurable views on this information for web and print on the other hand. So a new system was necessary that would overcome the problems presented. The TYPO3 based system bolognaT3 was chosen for this purpose.<span id="1252314076270S"><span id="1252314325711S"> </span></span>
