Stephanie Ulrich

Stephanie Ulrich belongs to those who were enthusiastic about software testing even back in the nineties, at a time when quality assurance did not have the status it has today. Consequently, she was not distracted by one of her former bosses, who asked her: „Why do you want to test? Do something interesting instead – data modelling for example.“ (...)

It was a Year 2K project which introduced Dr. Matthias Hamburg, a software engineer of long-standing experience, to the new world of systematic software testing. As he checked through entire IT landscapes, the IT expert, who today is Managing Consultant at Sogeti Deutschland GmbH, realized quickly that software quality assurance was not something that is here today gone tomorrow, but rather something promising significant potential for the future.(...)

Timea Illes-Seifert

What is so special about software testing? For Timea Illes-Seifert the answer is easy: For her, quality assurance is distinguished primarily through an engineering approach and through the great variety of activities associated with it. This was the experience the software technician has made in all assignments where she was responsible for testing: during her studies, in projects in the economy or in the context of research projects.

Maud Schlich

„You don’t test enough!“ Maud Schlich remembers these words from one of her former bosses very well, said during her time as a student trainee when she first came into contact with software testing. She soon realised that this work is not made up of dull theory and formal documentation, but rather points to new ways for quality assurance and testing, which will help to solve problems in organisations or prevent problems from arising in the first place.

Dr. Uwe Hehn

Dr. Uwe Hehn was already testing software when most computer scientists had not even heard of quality assurance (QA) as an independent discipline. In those days, QA was mainly limited to developer testing performed in parallel to programming. Even literature on the subject was difficult to find back in the nineties. (...)

Jörn Münzel

„At the start, things just happened this way “, says Jörn Münzel. After studying at the Technical University Darmstadt, he started out testing IT systems at Danet GmbH according to the requirements of the then postal authority. He soon realized that his mentality for analytical and structured thinking and testing matched perfectly. Twenty years on and considerably richer in professional experience, the software professional with a master degree in computer sciences today leads the Competence Center of the ITinera Consulting GmbH & Co.

Anke Löwer

„Anke Löwer came into contact with software testing at an early stage: The subject course „Software reliability“ at the Fulda University of Applied Sciences and a committed professor, who taught methods in step with actual practice, aroused her interest. Today, she works as a consultant for the IT-consultancy „corporate quality consulting GmbH”, and gives training courses herself on the subject of software testing. As a trainer for the ISTQB® Foundation Level she contributes to the things which fascinated her most during her study of computer sciences: to teach the course contents in a way that course participants can directly apply in their everyday work.
