First off it is a nice clean design.
However I'm going to present some counter opinions.
I'm not a fan of the collapsible sections.
- If they start collapsed then the user has to take an extra step to expand then to do their work
- however if they start expanded, I don't see the benefit in closing the sections (and thus even providing the option)
The caveat would be if the sections are drastically different, accessed by many users and thus each may want to hide the sections they don't care about.
The progress bar is neat, but if it isn't for a multi step form split across screens (where knowing how far into something you are is important) then I think it is actually just visual noise.
Eg the user's task is to fill in the employee form... I don't think part of the way through they are wondering... "I wonder, am I 67% the way through this form?"
In my experience the user's main goal is to complete a form as quickly as they can so they can do whatever it is they need to do next. Everything we can do to simplify forms making them quick, easy & clean is what improves their user experience.
