Service specification

January 28th, 2015

Doctoral thesis committee for Biljana Bajić’s thesis entitled ’Animation-Based Service Specification, Verification and Validation’, supervised by Prof. Alain Wegmann, EPFL.

“Service specifications are used to represent the service systems on different levels of abstraction: from business down to IT. High-level service specifications are mostly used for the communication among different participants, to catalyze the discussions between them, but only service specifications modeling IT systems have enough details to be simulated and executed. As a consequence, it becomes difficult to create precise specifications on high-level of abstraction, potentially leading to severe project problems. This can be compensated with use of formal methods and code generation techniques to get abstract, yet precise specifications, whose services can be simulated and prototyped. By capturing design decisions, the high-level service specifications can be refined into more detailed ones with possibility to validate the specification at any level of abstraction.

Winter school on design science

January 12th, 2015

Winter School on design science and design thinking in IS, organised by CUSO at Ovronnaz from January 12 to 16th, 2015, with Prof. Jean-Henry Morin, University of Geneva

The objective of this course is to offer PhD students in information systems (IS) and computer science (CS) the methodological foundation of design science research and design thinking. Combining theoretical, hands-on sessions and invited lectures, this course will provide PhD candidates with the required methodological foundation for their research.

The course will address design science from various viewpoints: frameworks, paradigms, theory, processes, patterns, evaluation, ideation and rationale. The design techniques will be used in creative ideation workshops, scientific literature reading and reviewing, writing research proposals, drawing scientific posters and presenting oral slideshows. The course is structured around two main aspects of design:
- Design Science (Vaishnavi and Kuechler, 2008) as the methodological foundation of research in IS and CS
- Design Thinking (Brown, 2008) as the creative foundation for innovation and design.

Business models in cloud computing

January 7th, 2015

Doctoral thesis committee for Andrea Giessmann’s thesis entitled ’Designing Business Models of Cloud Platforms’, supervised by Prof. Christine Legner and co-supervised by Dr Katarina Stanoevska-Slabeva, with Prof. Niels Bjørn-Andersen (Copenhagen Business School), as external referee.

“First, based on case study research, the thesis provides a deeper understanding of current Platform as a Service (PaaS) business models and their evolution. Second, it analyses and simulates consumers’ preferences regarding PaaS business models, using a conjoint approach to find out what determines the choice of cloud platforms. [...] The third part introduces a design theory for the emerging class of PaaS business models, which is grounded on an extensive action design research study with a large European software vendor.

Hitchhiker’s guide for dynamic ridesharing

January 5th, 2015

Bonazzi, R., Pigneur, Y. (2015) The Hitchhiker’s Guide to the Galaxy of Dynamic Ridesharing, HICSS

Dynamic ridesharing is a form of carpooling that allows anyone in a city to hitchhike a ride on short notice. Firms like Lyft and Uber have location-based applications for smartphones that are said to revolutionize this sector of transportation. Nonetheless, this mobile service is still in its infancy and there is a constellation of alternative solutions, with no reliable way to benchmark their diffusion across cities. We propose a method that treats dynamic ridesharing like a virus and (1) collects data from Google trends, as if it were a flu; (2) monitors its viral diffusion by implementing an epidemiological model; (3) infers strategic choices of a firm and represents them on a business model canvas. Our data analysis illustrates that (a) the Susceptible-Infected-Susceptible model performs better than the traditional S-shaped curve, and (b) our method allows us to estimate the evolution of new users and dropped users in every city.

Culture Map

December 30th, 2014

Nice skype chat with Alex and Dave Gray (blog) discussing his Culture Map. “Toolsmiths at work” dixit Alex …


Dave authored two interesting books: “Game storming” and “The Connected Company”. His company XPLANE has also drawn business model cases for BMGEN. Last year, he participated to our Business Design Summit (post) when he first introduced his Culture Map: “a tool that organizations can use to assess, map and transform their cultures. The Culture Map tool is still in the prototype stage and I am currently testing it with organizations large and small  … (more)
