Ask HN: Can Overly Streamlined UIs Lead to Unintentional User Actions?

We make software for very busy people (clinical and analytical laboratories) and two things we need to always keep in mind:

- our users are not (always) technically literate but will quickly learn very specific workflows (eg click there, then click there, then do that, done). If the workflow is always the same, eventually they won't always pay attention to what the UI says. They rely on muscle memory to get things done.

- If workflows end up being too complicated (too many clicks, or screens) we get told that it gets in the way. But because of #1 they quickly adapt.

So we need to keep a balance between too easy to make mistakes, and too complicated to make it quick.
