At work, I connect business and IT using a variety of experiences and knowledge gained in different areas of activity – from testing, through analysis and requirements engineering, to process management.
Outside of my professional career, I am involved in a number of non-profit activities aimed at improving software development methods and I am an active member of several organizations acting to increase knowledge and maturity of requirements engineering and QA community.
Between 2011 and 2013 I was an active member of REQB® Board. Today, I continue work on RE standardization in IREB®. I am one of the main authors of IQBBA® certification scheme for business analysts and co-author of ISTQB® Acceptance Testing certification program.
From March 2018 to May 2020 I was president of Polish Testing Board (SJSI). Since March 2018 I am a member of the Executive Board at IREB®.

For more than twenty years, Rainer Grau has accompanied companies on their way enterprise agility. He supports companies in their efforts to continuously develop and create sustainable value for customers and employees. For him, it is particularly exciting to find out which methods, techniques and approaches are suitable for scaling agility and building the right product and the right service for the customer. Business analysis and requirements engineering are two essential disciplines in this context, which also generate high value in an agile setup - even if perhaps lived completely differently compared to a classic project approach.

Rainer's background of experience in business agility is based on his consulting work with companies from various industries. Stages of his professional life include Distinguished Consultant and Partner at Zühlke Engineering, Head of Business Development at digitec Galaxus, responsible for courses at universities of applied sciences on the topic of agility, founder of the Swiss Agile Leaders Circle, founder of Denkplan Verein and active involvement in communities around agility, business analysis and requirements engineering.

If there is still time left, Rainer Grau likes to spend it with his family, doing sports, playing his guitar and reading novels.
