Ministerial responsibilities - who's doing what?

So what have Government Ministers been doing for the last week? Almost five working days after they were appointed, there are many junior Ministers who seemingly do not yet know what they are supposed to be doing. Only a handful of departments have published the responsibilities of their Ministerial team. So what have they been up to? Arguing over who is in charge of photocopying? Debating the wallpaper for their new offices?

And if they do not what they are doing - why haven't we been told?
