Van Lanschot Kempen, like many financial institutions, was moving quickly to adopt AI capabilities. However, it led to a fragmented internal experience. Different product teams were developing AI features in isolation, without a shared design language or consistent interaction model.

As a result, the organization experienced operational fragmentation. Bankers were forced to constantly switch contexts, while trust in AI tools declined due to inconsistent and unpredictable interaction patterns.

The cognitive load of "prompt engineering" often outweighed the benefits of AI. Users explicitly requested structured inputs (templates, presets) to bypass the "blank canvas" paralysis.

We assumed users wanted conversation. What they actually wanted was efficiency.

We found that trust in AI is risk-dependent. Users treat AI as a "Junior Analyst": helpful for drafting and exploratory work where they maintain control, yet potentially dangerous when used for advice that carries legal or professional liability.

A single “Chat” interface oversimplifies financial workflows. Depending on the situation, users may prioritize speed and convenience or demand transparency and accountability. These contextual shifts require flexible interaction patterns rather than a one-size-fits-all chat model.
