The initial situation

In 2008, the business processes in the bus department of MAN Truck & Bus AG in Salzgitter were changed. In the course of the reorganisation, the responsibility for the specific applications in the bus department were assumed by the central IT departments in Munich. It was as part of this change that MAN Truck & Bus also decided that the maintenance, support and the development of certain applications should be outsourced to external service providers.

The solution

TRIOLOGY GmbH had already been a service provider to MAN Truck & Bus AG in the area of application development for many years before 2008. Starting in 2008, the services of TRIOLOGY were then also called upon as service provider (maintenance and support) for entire application packages by MAN Truck & Bus AG. A team of permanent contact partners takes over the transparent communication with MAN Truck & Bus AG, controls the activities and so ensures the functionality and the operation of the applications.


  • Release management
  • Coordination and planning of changes
  • Technical documentation, as well as documentation of the maintenance and support activities carried out
  • Drafting of a functional and technical concepts
  • Development in accordance with Kanban and Scrum. The preparatory development takes place in an in-house development environment. The implementation of new releases is carried out remotely with restricted access.
  • Coordination with the data centre provider
  • Schedule planning and coordination as well as participation at regular meetings held on site
  • Test management and automation

The result

TRIOLOGY GmbH ensures MAN Truck & Bus AG continuous and secure operation thanks to the maintenance and support of the application packages.

The professional development specifically stands out through the comprehensive understanding of the processes because changes and demands are tested for plausibility and suitability within the application package.

This is guaranteed by the team through active participation, as well as conception and technical know-how, which involves new specifications being agile developed and optimally incorporated into the existing business processes.
