In order to remain competitive in the digital transformed
economic world, the perfect match of supply and demand
through supply chain management and operations management
is of essential importance. Productivity, quality, costs
and customer satisfaction are of major interest for companies.
Programs aimed at improving these factors are often
launched under the label "Operational Excellence" (OPEX),
which literally means "excellent operational performance"
. The pursuit of operational excellence contributes signi
cantly to the success of companies  and is intended
to secure long-term survival . The aim of this work is to
evaluate how decision support systems can help to achieve
operational excellence. For this purpose, literature was analyzed
to derive requirements for decision support via an
OPEX framework in manufacturing systems.
