> Another problem I've seen at work with the "design first" approach vs planning for technical feedback on an initial design: our frontend engineers would take the design and implement it exactly as is, papering over differences between the data entry and the underlying data model as needed — then users get confused about what exactly each option or interaction does. It's close enough to be serviceable (and not get fixed) but different enough to be annoying. This is where you should design wireframes first (e.g. rough greyscale sketches), turn them into clickable prototypes (Figma and InVision let you link up wireframes this way), and get feedback on these from user testing and the developers before creating high-definition designs or doing any coding.
