The Expert Team Lead leads a group of specialists, e.g. a group of SMEs or a specific technical area such as a group of operators. For example, this role can lead and steer a virtual group of experts with the participation of other IT departments on the topic of print management. The role serves as the interface and contact of the SAP basis to other specialist areas such as memory management or operating systems. In cooperation with other IT departments, the Technical Team Lead leads expert groups. These expert groups are usually virtually organised and their existence limited in time. The role of the Technical Lead functions as (partial) project leader for topics and projects of particular importance to the SAP basis. He takes care of all the activities involved in project management and control.
