ake the new system more expensive to run overall. Scaling the system to add more processing storage and processing power when needed would also be simpler as this can be done through the cloud package’s application programming interface (API), rather than having to acquire and physically install new hardware. It would mean the responsibility for supporting and maintaining hardware, and aspects of network security, does not lie with the council, though it also carries a risk of technical lock-in. This is, broadly speaking, where the cost and technical difficulty of switching any element of the system away from the chosen provider becomes prohibitive, which can mean significant problems when the provider decides to raise the prices of or stop offering particular services. Analysis This describes the step in the processing of data where the data used to create aggregated statistics derived from data in the main database, such as averages, totals and historical trends, are created, visualised, and then stored. The TFD’s main purpose is to compile and visualise existing data from disparate sources. Generally, it does not produce new pieces of data, save for the results produced by the targeted risk models, which work off TFD data and are then presented in the TFD frontend view alongside other data. Visualising Data and Insights: Dashboards and other tools The data is presented to practitioners in a useable and insightful way to complement their decision making. Practitioners access the data through an internally available website and apps. The site provides several ‘views’ which present information from the TFD in different ways including focuses on individuals, families, and professionals involved in a case. A permissions system ensures professionals can only access the vie
