I develop firstly for data entry and smallest amount of user inputs then go design SW from there. The UX/UI is often the hardest in terms of making your SW the easiest or shortest way to get to your functionalities. When a SW design hits a roadblock based on misordering of UI data entry or missing (or even too extraneous) of a user input, then reconciliation effort is made on SW/UX.
