With the focus of manufacturing companies on the digital transformation, Manufacturing Execution Systems
are market-ready, modular software solutions for manufacturing companies to integrate the value-adding
and supporting processes horizontal and vertical in the company. Companies, especially small and mediumsized companies, face high internal and external costs for the implementation of the MES modules. An
advantage of MES is the possibility to implement the systems in a continually, module-by-module approach,
with the benefit of timely distributed investments. By realizing fast improvements, companies can use the
benefits for further module implementations. This paper proposes a maturity model to measure the impact
of an MES on the digital transformation of the company’s production systems. The model fulfils two
purposes. The first, companies can measure the impact based on the difference between its current maturity
index and the potential index of an implemented MES. The second is, the user can identify what impact an
MES has in general on the digital transformation since the developed maturity model is derived from an
established industry 4.0 maturity model. The development of the maturity model is based on the
methodologies of AKKASOGLU and focuses on the further development of an established model. As an
outlook, the application of the model will be described briefly. The proposed maturity model can directly be
used by practitioners and offers implications for further development of MES functionalities.
