My first research project, back in 2002, was a collaboration with BMW. We were doing model-based testing of their MOST network master, using the approach Alex Pretschner had built in his PhD. We spent a lot of time with the BMW engineers building a detailed model in AutoFOCUS and
Also at the German Software Engineering conference, we had a keynote by Olaf Kolditz of the Helmholtz Centre for Environmental Research. He talked about the software side of his large simulations regarding water quality, water resources, geotechnical systems and geothermal energy. Here are my sketch notes:
During the German Software Engineering conference here in Stuttgart (organised by Prof. Steffen Becker, yours truly and a lot of others), we had a keynote speech by Jonas Huthmacher on Lab1886. It is a separate entity owned by Daimler which aims at kickstarting disruptive new businesses. Here are my sketch
Detlef Zerfowski of ETAS gave an interesting talk at the Embedded Software Engineering Kongress 2018 about how the domain of automotive software is changing. Here are my sketch notes.
Spreadsheets are everywhere in the corporate world. They have become a standard tool for a variety of professions for tasks like calculating a budget or predicting risks. Hence, multi-million decisions rely on the correctness of these spreadsheets. Yet, a spreadsheet is not just an innocent document as a Word
Philipp Diebold from Fraunhofer IESE gave the keynote at today’s International Workshop on the Agile Development of Safety-Critical Systems at XP 2018. He reported on his state of the practice survey on agile in embedded systems development and the resulting Agile Potential Analysis. Here are my sketchnotes of
One important part of software maintenance is perfective maintenance. I understand it here as adding new features and functionality to the software system. Especially for developers new to a system or developer beginners, adding a feature to a large, long-lived software system can be a challenge. While looking through
I truly believe that abstraction is at the core of computer science and software engineering. Abstraction is essential to be able to cope with complexity and allows us to build the tremendously complex systems we build today. Yet, it is hard to clearly define what abstraction is. Florian Deissenboeck and
Walid Maalej presented his paper on the automatic classification of app reviews published in the Requirements Engineering journal. Here are my sketch notes:
The second keynote at our European STAMP Workshop was given by Ortwin Renn who is also professor at the University of Stuttgart but in addition leads the Institute for Advanced Sustainability Studies. He gave us a more general view on risks and how they are perceived. Here are my sketch
John Thomas from MIT reported on his experiences on applying STPA to more modern automotive systems. Interestingly, they found a lot of influence of the human, and he detailed a bit the process model and the human controller part of the analysis. My sketch notes:
Claes Wohlin gave a great keynote last week at the International Symposium on Empirical Software Engineering in Ciudad Real, Spain. He emphasised that we need to get better at creating empirical results that are puzzle pieces that we can try to fit together. That doesn't mean that that
