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.
