velopment of these models noted that they don’t use enough datasets that are of sufficient quality to guarantee accurate risk scoring: “I never thought we had enough data. I never thought the quality was good enough,” (Insight Bristol team) Purpose Limitation and Data Minimisation There was consideration of the exact purpose for which data was being used, which an IG specialist told us correlates to the tasks carried out by the staff teams that the TFD was designed for. The Insight Bristol team feel that this approach has been honed over time. They clarified that access to the TFD was granted on the basis of performing a safeguarding role, with a need to view data about a constrained group of individuals with defined support needs or possible safeguarding concerns.

In most cases this is explained by personal preferences, with practitioners able to access some of the datasets that the TFD visualises via other source systems, which can be accessed independently. Where users are unable to access datasets independently, such as with TFE users, many of those we spoke to described data as being minimised to the point of providing only broad contextual information: “There is minimal information on there, but it's probably enough to just give you a bit of an overview which can then potentially lead to some support conversations or helpful conversations with families.” (Family Support and Safeguarding Lead, Primary) However, in some cases some teams felt as though they had access to some data that went beyond the scope of their roles, for example, data from risk models which was developed only for ce
