Chair of Technology & Operations Management

TOM Mission

The Chair of Technology & Operations Management (TOM) is focused on issues of Technology & Operations Management which arise in technology-based enterprise with regard to new product introductions, operation and supply chain management, and the management of technology standards.

TOM’s mission is to be an internationally acclaimed academic institution with respect to development of new theories and concepts, transfer of research into practice, quality of its teaching, as well as the placement of its graduates.

The TOM chair is led by Professor Ralf W. Seifert.
