Context
Wagner develops safety-critical fire protection systems that regulate oxygen concentration in enclosed spaces. The operating corridor is narrow: too little oxygen endangers human life; too much oxygen compromises fire suppression. Every system change requires TÜV certification. Traditionally, certification cycles were long and unpredictable, severely limiting the organization’s ability to deliver changes quickly.
Wagner’s objective was not merely to improve modeling, but to build a development platform that would drastically reduce certification lead time while maintaining safety and compliance.
Architect for Flow
Wagner invested in a coherent Structure engineering platform that integrates model-based design, traceability, Verify automated regression testing, simulation, and hardware-in-the-loop infrastructure. MBSE approaches such as structured interfaces, ports, and traceability allow requirements, architecture, implementation, and tests to remain consistently linked.
Package Certification itself is embedded into this platform. Package Regression tests are executed in a controlled (phyiscal) TÜV-supervised environment where neither Wagner nor TÜV can alter the setup independently. Test inputs and outputs are fully digital. This stabilizes the certification interface and turns approval from an ad-hoc event into a defined system capability.
Rather than optimizing individual projects, Wagner optimized the platform that produces them.
Accelerate
Once the platform was in place, automation enabled continuous regression testing, simulation, and structured integration workflows similar to a software factory. Not notably, Verify certification readiness is continuously maintained instead of prepared manually for each release.
Package As long as no fundamentally new test categories are required, TÜV approval can now be completed within days. Changes that once required many months can be delivered within a few weeks, including certification. The organization reports being roughly three times faster than before, while improving quality.
Speed emerged not from shortcuts, but from architectural investment and disciplined automation.
Outcome
By building a certification-ready engineering platform, Wagner transformed regulatory approval from a rigid bottleneck into a predictable, repeatable process. Certification speed became a systemic property of the platform rather than a project-specific negotiation, as well as a competitive advantage.
The key was not modeling in isolation, but platform architecture that enables automation, traceability, and trusted collaboration with the regulator. Certification is no longer the constraint that dictates delivery speed.
