Bingo. Training should be done to show users how to operate software if good UX can’t make it apparent.
Very stupid example: you want to save a document. I could put a save button on the toolbar, put it within File menu, or bury it under File -> Document Actions -> Write To Disk.
If EHR does the latter and ppl need training how to save their work, u will almost always need useless training and hand holding, where a better UX design would have avoided this.
