Small hole in all data governance plans
Users are allergic to digital hygiene. Unlike missing a shower, you won’t smell funny and your coworkers aren’t going to mock you. There’s no social incentive whatsoever to clean up after your digital self.
And thus only the rare neurotic ones ever bother.
Any data management exercise that doesn’t realise there will be zero actual buy in from day to day users is doomed to failure at the start.
