As part of the Vendo program, a team of over 400 employees is developing DB’s new sales system for passenger transport. The “Komfort Check-in” team is replacing the original MVP infrastructure for KCi on the backend, thereby ensuring the process is future-proof.
The challenge
As the first customer-facing feature of the emerging Vendo platform, the Convenience Check-in Services are already establishing integration with the app, the ‘legacy’ sales core system, the BahnCard and reservation systems, and the ticket validator. Owing to this pioneering role, many development and operational processes for DB Vertrieb’s virtual private AWS cloud are only being established with and through the KCi team.
Our solution
The client has filled more than half of the mixed team with iteratec staff: technical product owners, architects, business analysts and developers; once again, the team is led by iteratec experts from the KCi MVP (“Beta”: check-in with reservation). The team develops and delivers new services using a test-driven approach within a DevOps framework. It will phase out the MVP ‘seamlessly’ in two migration stages before introducing new features such as check-in without a booking.
The added value
Passengers can use the new KCi ‘Check-in without a booking’ feature or be checked in by a member of the on-board crew.
KCi for mobile tickets from legacy systems has been migrated to the new Vendo platform at an early stage, ensuring it is future-proof. This eliminates the need for a dual investment in upgrading the legacy systems.
The KCi go-lives provide a wealth of insights for the development, roll-out, operation and security of Vendo services. The iteratec staff members responsible share these insights within a new cross-functional technical team to help prepare other development teams for their go-lives.

DB Vertrieb is the in-house service provider responsible for the sale of all mobility services across all sales channels (the DB Navigator app, bahn.de, customer service centres, ticket machines, on-board sales, call centres, partners, etc.).
The migration to Deutsche Bahn’s new Vendo sales system was completed in 2024. In this interview, Ralf Gernhold, Head of IT Sales Platform at DB Vertrieb, and Martin Schönhoff, Principal IT Consultant at iteratec, explain how they successfully modernised this business-critical system whilst operations continued as normal.
