If your company chose Qlik as a (self-service) BI tool, GDPR requires you, amongst other things, to be able to document which data you hold, where the data is stored, who has access to the data and how the data is used.
Do you observe a decline in Qlik platform performance? Do you have turnover in technical staff or changes in business structure or BI environment, and troubles dealing with it? Or do you think you might get more benefits from your QlikView or Qlik Sense investment? Then a Health Check is something you should look at!
