The app UX for navigating large amounts of data still really sucks in most enterprise apps today. The hierarchical list of categories, subcategories, and sub-subcategories should have been left on those complicated web screens where we had the screen space and user patience to finagle with them.
Going mobile means changing the way people interact with their information. The whole “intuitive interface” phrase means the user expects to touch and interact with the data, not just flip between screens to narrow in on what they’re looking for. Yes, having a search field for combing through that data is helpful but it doesn’t solve the problem for enterprise app UX.
