Besides the shared overall responsibility for SAP's strategy and business development, Kagermann also oversees the areas of product development for large enterprises, global communications, internal audit, and top talent management.

Kagermann joined SAP in 1982 and was initially responsible for product development in the areas of cost accounting and controlling. Later, he oversaw the development of all administrative solutions, including human resources, as well as industry-specific development for banking, insurance, public sector, and healthcare. His duties also included finance and administration as well as the management of all SAP regions. He has been a member of the SAP Executive Board since 1991. Together with Hasso Plattner, co-founder of SAP, he was co-CEO from 1998 to 2003, and became sole CEO when Plattner moved to the supervisory board in May 2003. In order to prepare for a succesful leadership transition, Kagermann asked the supervisory board to nominate Léo Apotheker co-CEO in April 2008.
