- PublikationEin menschlicher Eignungstest für objektorientierte Programmierung im Kontext von KI und maschinellem Lernen(Springer, 2023) Telesko, Rainer; Jüngling, Stephan; Dornberger, Rolf [in: Neue Trends in Wirtschaftsinformatik und eingesetzte Technologien]Viele aktuelle IT-Systeme werden auf der Grundlage des objektorientierten (OO) Programmierparadigmas implementiert, das sich in mehr als zwei Jahrzehnten als einer der erfolgreichsten Mechanismen für die Wiederverwendung und Erweiterung von Code erwiesen hat und in vielen Softwarekomponenten und -systemen verwendet wird. In Verbindung mit einem soliden Verständnis von Geschäftsprinzipien und guten Kommunikationsfähigkeiten gilt OO immer noch als eine der Kernkompetenzen bei der Entwicklung von Plattformen und Systemen, die unsere heutige IT-Landschaft bestimmen. Der Selbsteinschätzungstest, den wir als Frühindikator für angehende Studierende der Wirtschaftsinformatik (BIT) entwickelt haben, gibt Aufschluss über das Kompetenzniveau von Studienanfängern und -anfängerinnen und dient als Ausgangspunkt, um über Abstraktionsfähigkeiten im Kontext der aktuellen Digitalisierung und der Zunahme von Komponenten der künstlichen Intelligenz (KI) nachzudenken. Der Artikel erläutert die Relevanz des OO-Denkens auf verschiedenen Abstraktionsebenen im Kontext des Lebenszyklus aktueller Systemarchitekturen und gibt einen Ausblick darauf, wie diese Abstraktionsfähigkeiten beim Wechsel von einem OO-Entwicklungs-paradigma in einen neuen Bereich wiederverwendet werden können, in dem KI und maschinelles Lernen ihren Einfluss auf den Gesamtentwurf von Software-systemen stetig vergrößern werden.04A - Beitrag Sammelband
- PublikationEchtzeit Ressourcendisposition von Personal und Rollmaterial in der Eisenbahnbranche(Innosuisse, 2023) Ehrenthal, Joachim; Hanne, Thomas; Telesko, Rainer; Gachnang, PhillipZu wenig Personal und Rollmaterial, kurzfristig angesagte Arbeiten an der Infrastruktur mit den entsprechenden betrieblichen Behinderungen und Einschränkungen sowie kurzfristig auftretende Störungen prägen zurzeit die Berichterstattung über die Entwicklungen im öffentlichen Verkehr der Schweiz. Es ist absehbar, dass sich diese unbefriedigende Situation über eine längere Zeitspanne kaum massgeblich verbessern wird. Umso wichtiger ist es, vorhandene Ressourcen optimal einzusetzen und den zukünftigen Bedarf an Mitarbeitenden und Rollmaterial in den Griff zu kriegen. Die Fachhochschulen der Ostschweiz (OST) und der Nordwestschweiz FHNW entwickelten mit der Südostbahn (SOB), den luxemburgischen Eisenbahnen (CFL) und der Eisenbahn-Softwareherstellerin Qnamic eine zukunftsweisende Software zur Unterstützung der Eisenbahn-Disposition, um in Echtzeit über situationsspezifische Massnahmenpakete zur Störungsbehebung zu verfügen.05 - Forschungs- oder Arbeitsbericht
- PublikationRequirements engineering in agile software startups - insights from multiple case studies(Springer, 2021) Gupta, Varun; Hanne, Thomas; Telesko, Rainer; Silhavy, Radek [in: Software engineering and algorithms]This exploratory case study was conducted with five IT startups in order to investigate how requirement engineering-related activities are performed and what is the state of maturity with the practices & tools used. Another objective was to study that how the startups managed their practices during Corona Virus (COVID19) pandemic time. The results indicate that flexibility and access to the online tools were the main strengths of the startups to cope up with the pandemic situation while fluctuating market demands affected them marginally. The startups do vary in domain, team size, practices and selection of the tools, with matured startups having more structured (but flexible) processes compared to younger startups. The young startups have the opportunity to learn from the practices of the matured startups, to adopt the learning in their working context. The previous software development experience of the startups and its founders does affect the maturity of the practices and selection of the tools. The flexibility and agility as evident in the working context of the startups helped them to turn pandemic situation into their business opportunities.04A - Beitrag Sammelband
- PublikationA human aptitude test for object-oriented programming in the context of AI and machine learning(Springer, 2020) Jüngling, Stephan; Telesko, Rainer; Dornberger, Rolf [in: New trends in business information systems and technology. Digital innovation and digital business transformation]Many current IT systems are implemented based on the object-oriented (OO) programming paradigm, which over more than two decades has proved to be one of the most successful mechanisms for code re-use and the most powerful extension mechanisms used in many software components and systems. Combined with a solid understanding of business principles and good communication skills, OO is still considered to be one of the core skills in the design of platforms and systems that drive our current IT landscape. The self-evaluation test, which we developed as an early indicator for prospective Business Information Technology (BIT) students, revealed insights about the skill level of beginners and serves as a starting point to reflect on abstraction skills in the context of the current digitalization and the increase in artificial intelligence (AI) components. The article explains the relevance of OO thinking on different levels of abstraction in the context of the lifecycle of current system architectures and provides an outlook on how these abstraction skills can be re-used when switching from an OO development paradigm into a new area where AI and machine learning will steadily increase their influence on the overall design of software systems.04A - Beitrag Sammelband
- PublikationPreparing management science students for the digitalization era(IATED, 2019) Dannecker, Achim; Telesko, Rainer; Knechtli, Hanspeter; Gómez Chova, Luis; López Martínez, Agustín; Candel Torres, Ignacio [in: EDULEARN19. Conference Proceedings]One of the big challenges today are innovative teaching concepts for business students in the area of digitalization. At the beginning of their study, students mostly understand only the basics of IT mainly related to their private (mobile) environment and not real business scenarios such as data management, outsourcing and/or business process management.04B - Beitrag Konferenzschrift
- PublikationChecking the students aptitude for a bachelor program: experiences with a web-based tool(2018) Jüngling, Stephan; Telesko, Rainer; Reber, AndreasResearch Abstract: Checking the student’s aptitude for a Bachelor program: Experiences with a Web-based tool Research Objectives: In autumn 2014 the Bachelor program „Business Information Technology (BIT)” has been launched. BIT is about the application of information technology in business with the focus on building information systems. Since several terms, it can be observed that a considerable number of students faces difficulties in modules related to programming and mathematics at the beginning of the study. In order to monitor the aptitude of the program for beginners a project was launched with the aim to develop a method and a web-tool supporting the self-assessment related to indispensable competencies in the BIT program. Methodology: The aptitude test - built with Google Forms - currently consists of 31 predefined multiple choice questions and calculates an overall aptitude value and single aptitude values for the main categories logical and analytical thinking, understanding algorithms and abstract thinking. The questions are taken from well-established test systems like ELIGO-System, BOMAT, CASA etc. and are typically solved within less than 45 minutes. The students can check their suitability for the study programme by comparing their overall aptitude value with a given threshold. First test runs conducted with the tool confirm the validity of the aptitude test. The future scope will involve more students and deal with an analysis of concrete weaknesses that can be used as input to adapt the settings of programming and mathematics modules.06 - Präsentation
- PublikationRoad to agile requirements engineering: lessons learned from a web app project(Springer, 2018) Telesko, Rainer; Dornberger, Rolf [in: Business information systems and technology 4.0. New trends in the age of digital change]This chapter describes the research project Companion conducted at the University of Applied Sciences and Arts Northwestern Switzerland FHNW and its relationship to the research area Agile Requirements Engineering (ARE). ARE aims to establish requirements engineering practices, which are customized for agile development methodologies such like Scrum, XP, etc. Within the Companion project a Web App was developed to promote mental health of adolescents taking their first steps into working life. The description starts by giving some key information about the project, its context, the development of the Web App and the weaknesses observed during software engineering activities. Next, classical requirements engineering and ARE are compared and specific challenges for ARE based on experiences from the industry are presented. For the challenges in ARE, specific practices have been proposed which are described together with their limitations. This chapter ends with a selection of adequate ARE practices which may increase the performance of software engineering in situations similar to the context of the Companion project.04A - Beitrag Sammelband
