In the full-length edition of this InfoQ article by Lejla Vulovic and Ana Nadwill, they share practical experiences and provide concrete examples from their work with multi-site teams that built a digital banking solution and delivered value to customers across various European markets.
Their banking group, headquartered in Vienna, operates in eleven Central and Eastern European (CEE) markets and serves approximately eighteen million customers. They aim to bring real-life stories and lessons learned from developing two banking products, Lending and Foreign Exchange (FX), and their evolving architecture over time.
In building a banking solution that spanned multiple countries, the team adopted a collaboration model grounded in Conway's Law, which helped them optimize for faster customer value delivery while avoiding the duplication of local solutions. By defining common goals early and ensuring they were well understood across markets, the teams could align architectural adaptations with business priorities and proactively manage risks and dependencies.
The approach relied on continuously evolving communication structures, IT architecture, and organizational design, enabling the delivery of unified, scalable digital solutions. Agility and modern engineering practices were reinforced through ongoing education, the involvement of agile coaches at both team and leadership levels, and the co-creation of collaboration agreements.
Finally, shared activities such as group roadmapping and retrospectives fostered a "one-team" mindset, improving cross-country collaboration and enhancing agile practices across the organization.
