Hello! I think the strongest approach starts by understanding the users and identifying which parts of the process actually cause friction. From there, UX research and product strategy can guide the interface instead of simply making everything look cleaner.
I came across the digital product design agency Fireart Studio
https://fireart.studio/services/product-design/ approach and liked the idea of combining research, strategy, design, and development. It sounds suitable for applications where users need a simple experience despite complicated technology underneath.
