Looking back over 25 years of professional experience, a lot has come up: a company... 6 books... 55 employees... countless articles and presentations... and a whole lot of experience. My passion for project consultation might account for the fact that, until now, I do not "only" manage, but I am still directly involved in projects and remain close to customers. What drives me is the vision to implement good ideas so that developers, contractual partners, and users-both direct and indirect-face an intelligent, sophisticated, and beneficial product. In doing so, I work with a range of methods and approaches in agile and non-agile environments. In order to standardize qualification for requirements engineers/business analysts, I founded the IREB e.V. (International Requirements Engineering Board).
