How to teach blockchain in a business school
2018, Dettling, Walter, Dornberger, Rolf
There are different approaches to developing a syllabus for a “blockchain curriculum” in a business school. The following chapter identifies many questions which can guide lecturers through their own process of creating a blockchain syllabus. The list of topics and figures presented indicate how much time could be spent on these topics. This list does not present a definite syllabus, because the essence of blockchain is that it is a holistic approach which goes beyond naming topics. It raises certain questions and is intended to start a broader discussion which will eventually lead to a systematic approach to this multidimensional challenge. Structuring this journey leads to the following four main questions, which are considered relevant in this discussion: What are the key research topics in blockchain? What is the impact of blockchain and by what criteria do we define impact? Which building blocks of blockchain are relevant to understanding the blockchain mechanism? Which applications (beside Bitcoin) should be discussed and are expected to become important in the near and distant future? This journey closes with some methodological remarks based on my experience of teaching blockchain classes. Finally, it is obvious that any curriculum will be condemned to continuous adaption because blockchain technology is changing in an ongoing way.
Mobile Communication Price Parity and index: Making Money off the poor
2016, Dettling, Walter, Hitz, Anna
The price for mobile services is the most important determinant in the way low-income households use mobile phones. Based on existing data on mobile communication prices, a global index for measuring the price of mobile communication with 2G handsets has been developed. This index allows the comparison of price levels in different countries. The first step involves defining a mobile communication basket, containing a specific amount of speech and short messaging per month. The definition of this basket is based on the OECD definition of a standard basket of monthly mobile communication consumption (OECD, 2010) and targets the consumption Habits of low income users. Two different indices are proposed. A first calculation from the years 2009 to 2012 involving the indices of 149 countries provides a useful overview of the global mobile price landscape.
Netzreport 06: Informatik in Schweizer KMU - Die Bedeutung der Informatik in KMU und anderen Schweizer Organisationen
2006, Schubert, Petra, Leimstoll, Uwe, Dettling, Walter
In fast täglichen Auseinandersetzungen in der Fachpresse streiten sich Experten, welchen Stellenwert die Informationstechnik (IT) in Unternehmen bis heute erlangt hat. Dabei stehen sich oft zwei Meinungen diametral gegenüber. Die eine Fraktion glaubt in Anlehnung an die vor über 20 Jahren postulierten Theorien von Porter und Millar (1985) an ein besonderes Potenzial der IT zur Erzielung von Wettbewerbsvorteilen. Die andere Fraktion steht auf dem Standpunkt, der Diffusionsprozess der IT sei mittlerweile so weit fortgeschritten, dass sie im Unternehmen bereits zu einer so genannten "Commodity" (also zu einem für alle verfügbaren Gebrauchsgegenstand) geworden sei und damit ihre Tauglichkeit als strategisches Differenzierungsinstrument eingebüsst habe (Carr 2004).Ebenfalls kontrovers diskutiert wird seit Jahrzehnten die Frage, ob der Einsatz von IT zu einer höheren Produktivität führe.
Was man mit Blockchain nicht machen kann
2019-06-19, Dettling, Walter
Nach der ersten Begeisterung über Kryptowährungen und Blockchain ist eine gewisse Ernüchterung eingetreten. Im Gegensatz zu Kryptowährungen ist bei den übrigen Blockchain-Anwendungen ist noch keine «Killerapplikation» in Sicht. Grund dafür sind die völlig unterschiedliche Konzeptionen von herkömmlichen Datenstrukturen für Business Applikationen und dem Konzept der Blockchain, welche primär den Schutz der Daten vor Manipulation und die Anonymität gewährleisten.
Informatikausbildung in der Schweiz: Wir müssen dranbleiben!
2013, Dettling, Walter
Seit mehr als 20 Jahren hören wir, dass die Schweiz viel zu wenige Informatiker ausbildet. Aktuell droht über 2000 Informatikern bei der UBS die Kündigung. Haben wir nun zu viele oder zu wenige Informatiker? Oder vielleicht nicht die richtigen?
Roadmap on Blockchain Transformation for Organizations – Evaluation through Teaching
2019, Dettling, Walter, Flück, Lia, Dermol, Valerij
Even though blockchain technology is currently a widely discussed topic, it is hard to get a straightforward overview or understanding of this topic. For many organizations blockchain causes excitement about the opportunities for innovation but raises also doubt and fear of losing their competitiveness. Most managers have heard of blockchain technology before and feel the pressure to go with the market and implement the technology. However, most organizations do not know how to develop their company towards blockchain. The lack of knowledge includes how to build up knowledge, launch a suitable project, finding a use case that matches the organization, aligning it with their strategy, which kind of blockchain to focus on and how to start a business transformation. As a part of a research project about blockchain teaching and business transformation, a roadmap was developed that aims to support organizations in their transformation towards blockchain technology and in understanding the potentials of this new technology. This artifact was then evaluated through a proof-of-concept by gathering data on relevance and practical applicability of the roadmap. This was done by using the roadmap in a university class environment and an industry questionnaire. With the evaluation of the artifact in a class environment, a current state-of-the-art topic could be taught to students and, additionally, the learning process of the students enabled research contributions to the project results.

Informatiker-Ausbildung: Mehr Mut bitte!
2012-10-26T00:00:00Z, Dettling, Walter
Seit Mitte der 90er-Jahre werden wir auf einen eklatanten Mangel an Informatik-Fachkräften in der Schweiz hingewiesen. Das trifft auch heute im Jahr 2012 immer noch zu. Trotz der enormen Verbreitung von Informatik in Beruf und Alltag scheint es so, dass der Beruf Informatiker immer noch wenig attraktiv für junge Nachwuchskräfte ist.
