Functional and technical implementation of a system component

DB Energie GmbH is a wholly owned subsidiary of Deutsche Bahn and the group’s energy supplier. It operates a nationwide traction power grid.

MaibornWolff was responsible for the functional and technical implementation of a central system component for DB Energie GmbH. This component is embedded in an environment characterized by high regulatory complexity and a fixed, non-negotiable deadline.

Working closely with the subject-matter experts at DB Energie, the requirements were defined in the language of the domain and translated into a robust, automated process landscape.

Architecture Ensures Scalability for Peak Loads

The architecture was consistently aligned with the project’s key quality objectives: long-term traceability, scalability to handle peak loads, and the ability to correct errors.

This was ensured through a multi-stage, automated testing strategy that included business acceptance tests, which extended beyond company and technology boundaries to include external service providers.

On-time launch of the stable system

In addition, numerous peripheral systems were integrated into a multi-vendor environment. Thanks to forward-looking planning, the transition from the existing systems to the new one went smoothly.

Since its on-schedule launch, the system has been running stably in regular operation, with regular releases and short response times.
