The challenge The challenge

DZ Bank Group had three different software platforms used by over 400,000 people to fulfill B2B payments.

The challenge was to converge all three platforms in a future-proof software solution compatible with the latest technology while complying with new transaction safety and IT standards. It also needed to be simple enough for 400,000 people to feel confident to use it.

Working together with product managers at DZ Bank Group, we designed a new payment solution capable of satisfying diverse user needs, while an updated IT architecture minimized the need for IT support.


The insight The insight

We started by working with stakeholders and users to analyze the existing platforms, their functions, and IT architecture.

We then identified three core functions to focus on in the new UX concept: execution of bank payments, invoice uploading, and a real-time overview of transaction data.

The methodology The methodology

Following a lean-startup approach, the whole project took place in DZ Bank Innovation Lab. Using a combination of Service Design, Design Thinking, and Agile Development, we created a prototype in just three months.

The core team was an interdisciplinary mix of product managers, UX designers, developers, and a method coach.

The UX phase included extensive competitor analysis, user interviews, contextual inquiry, and usability testing.

“It was impressive to see how quickly the team understood our context and daily work, offering us unique customer insights. I was surprised by how quickly we achieved our first results.”

The solution The solution

An easy-to-use and intuitive transaction payment UX concept, validated and iterated in close collaboration with the user. As a result, DZ Bank now nurtures relationships with corporate clients, while creating IT synergies and cross-selling opportunities.

We used mid-fidelity screens to develop a working prototype, applying a modern Technology Stack that created a sustainable, unique user experience.

The viability of the new B2B Software was secured by a thorough business case and pricing strategy.
