System engineering
From system and implementation concepts, technical project management and development of tender specifications to commissioning and system integration.
NEXTRAIL defines successful teamwork in a project as processes that seamlessly intertwine. For all technical, functional and operational aspects. With the highest level of professional expertise in all disciplines.
The systems engineering expert teams at NEXTRAIL focus on constructive and cooperative collaboration as well as the perfect interdisciplinary interaction of our technology and departmental experts. This is how we provide reliable support from system design and gathering requirements, the creation of guidelines, support for tendering processes, and taking charge of technical project management and approval processes through to roll-out with commissioning and system integration.
To this end, we draw up service descriptions, implementation concepts, LCC evaluations and develop tendering criteria, requirement specifications and interface descriptions. All this from a single source – so that a holistic view of technical, functional and operational aspects is always maintained and that losses due to communication are a thing of the past.

Our services in the area of system engineering:
NEXTRAIL accompanies the process management of test and system integration over the entire life cycle of the project – up to commissioning and beyond. NEXTRAIL takes care of stakeholder management, document management and tracking necessary and already achieved test coverage, as well as overall system integration, its entire organization, all coordination and the establishment of the corresponding processes.
In addition to the test and system integration process management, NEXTRAIL takes care of the creation of all relevant test documents, from test concept and test matrix (centralized tracing of requirements for the test cases and test results across different test phases including versioning and release management), to the documentation of test results and reports over the entire duration of the project. Only this process-bound documentation can ensure successful testing at all levels.
Everything from a single source. In addition to the specification of test scenarios, NEXTRAIL can also assume overall responsibility, carrying out the tests, including planning and monitoring of the test drives. From system and subsystem tests, integration and field tests all the way to long-term monitoring of the system in operation and technology.
