Understanding the Users

The user is the one who spends the most time and effort working with the tool. Their efficiency multiplied by the number of users = HIGHEST PRIORITY AND ROI.

Designing from "backend forward" does not work. Backend designers/developers are not the end-users who request specific UX/UI. Their technical worldview often clashes with the mental models and needs of the general employee base.

Management's Vision vs. Reality "In the Trenches". If management is disconnected from the practical daily reality of workers, their ideas about tool functionality often create friction and unusable processes.
