Slow news day?
I would say that large numbers of organisations capture information that is not looked at after initial capture.
Typical example is for compliance purposes. Let's say an organisation needs to keep their email and telephone records for x years - those records are probably never inspected. The simple answer to the Data Protection issue is that the records are being kept for compliance purposes.
Any organisation that raises invoices will say that they have to keep copies of them for compliance purposes. Do they make use of them? Probably only if there's a query.
Of course those records could be made much more useful by sticking them in a Data Warehouse, or similar, but I get the impression that this is not within the context of the survey.
