I think GDPR is a bit of a minefield, not helped by the initial panic mode from many organisations, and some pretty dodgy guidance out there on some unofficial sites. I’m an Information Manager and so have spent many an hour in some pretty mind numbing workshops on it so far!! The key to me, is the word “consent”. It’s a very simplistic starting point and some scenario’s do need a lot of digging into the guidance, but if you keep that word in mind, then you won’t go far wrong.
