This is about Digital Service Standard, criteria 6 - consistent and responsive design. While it is great and should be always followed, here are some comments:
In my experience mobile first design strategy is easy for websites and simple applications, but when it comes to designing complex government applications / services where there is loads of content /questions / tables etc. sometimes it is easier to go responsive, rather than mobile first. I have seen some examples where mobile first approach leads to lot of juggling / navigation issues as often things are buried under icons / UI elements.
Mobile first should not be mobile only. I sometimes see same designs suggested for mobile and desktop - with the same hamburger icon and UI elements being used on desktop. Shouldn’t there be a desktop advantage?
Any similar experiences from anyone here?
