rve. Who developed these views and apps? The different views of TFD data have been developed by the Insight Bristol team in collaboration with the teams requesting and using the views and apps. Typically, in response to a request, exploratory work and prototyping is carried out prior to more substantive development work. The Insight Bristol team also get requests from teams to build new views, apps, or provide access to new analysis. To submit this request, teams fill out a work request form, which is then received and reviewed by a centralised team and the work is then allocated to the Insight Bristol team. However, requests can also be made directly to the Insight Bristol team. Who uses these views and apps? The Strategic and Aggregated views are used by managers across Bristol City Council to access TFD information at a ‘context level’ and as part of particular use cases. Examples include:  Early Intervention team managers (School Demand app)  Teams that use Qlik apps for management and reporting purposes (various teams and service managers) 4. Methods 4.1 Introduction To understand the overall effectiveness of the TFD as an approach, it isn’t sufficient to understand the outcomes it delivers alone, since these outcomes are contingent on the local delivery approach taken. Therefore, our research firstly focussed on evaluating the extent to which the TFD enables, or doesn’t, anticipated outcomes for practitioners and managers, as listed in the clarified theory of change (see below). We also undertook a process evaluation of the extent to which necessary implementation activities took place and to what levels of quality. In doing so, we were able to arrive at a rounded understanding of the value and effectiveness of the TFD as an approach, as well as determining whet
