Yes.
Most organisations must document their processing activities to some extent. Both controllers and processors have their own documentation obligations, but controllers need to keep more extensive records than processors.
The GDPR provides a limited exemption for small and medium-sized organisations. If you employ fewer than 250 people, you need only document processing activities that:
- are not occasional (e.g., are more than just a one-off occurrence or something you do rarely); or
- are likely to result in a risk to the rights and freedoms of individuals (e.g., something that might be intrusive or adversely affect individuals); or
- involve special category data or criminal conviction and offence data (as defined by Articles 9 and 10 of the GDPR).
The GDPR includes “health” as a special category. Therefore as a health provider, GP practices DO have to produce an Information Asset Register, even if it employs less than 250 people.
