His focus as a consultant and trainer is on test management, test process management and test process improvement.

After studying media informatics and information systems, he initially worked as a software developer for enterprise applications and as a research assistant at the Berlin University of Applied Sciences.

Dietrich Leimsner

Dietrich LeimsnerDietrich Leimsner likes to speak of the tester’s “dirty fantasy”, which cannot be replaced by machines, when he explains why even in times of test automation and AI-supported test case generation, the human element of the trained software tester must not be missing in comprehensive software quality assurance.

He has been with DB Systel GmbH, a Deutsche Bahn AG company, since 1999. At the then still quite new ticket vending machines, he learned directly at the interface of the digital (the sales data record) with the physical (the actual ticket) the attraction and challenges of comprehensive quality assurance. Therefore, since 2006, he has been dealing exclusively with this topic in various large systems with board and customer visibility.

In 2014, Dietrich Leimsner took over the design and further development of DB Systel’s test process as well as the responsibility for the associated methods and tools. In this context, he is now concerned with the challenges of software quality assurance and how this is perceived when the company reorganises itself in terms of structural and project organisation according to agile principles.

In the GTB, Dietrich Leimsner is involved in the Exam and Glossary working groups. In addition to this activity, he is active in the “Test, Analysis and Verification of Software” (TAV) section of the Gesellschaft für Informatik (GI) (German Informatics Society) (where he is a member of the “Job Profile Tester” working group).

Mr. Leimsner is a founding member of the ASQF working group “Test Data Management”.
