n Practitioner) For some practitioners this lack of information was enough to discourage their use of the risk models entirely: "'Does that mean it's quantified somehow, or is it just indicating that the risk is present? I don't know what I'm looking at; that's why I don't use it." (Social Care Practitioner) Such gaps in knowledge clearly present an issue in terms of the risk models enabling more effective practice. More broadly, it poses the potential issue of practitioners continuing to use the risk models to inform decision-making and still not being clear on what the outputs mean or how they are Social Finance Limited +44 (0) 20 7770 6836 87 Vauxhall Walk, London SE11 5HJ socialfinance.org.uk 46 derived. During our observation, however, it should be noted that the practitioners we spoke to described how the TFD and the risk models supported their decision making, rather than directing it. Indeed, many noted that, as it became clear the risk models were inaccurate, they decided to stop using them. 5.4.2 Time-saving There is evidence of inaccuracies leading to time wastage Staff members who were engaged in the process of crafting these models emphasized that their primary objective wasn't geared towards facilitating time-saving measures for practitioners. Nonetheless, it became apparent that the subsequent iterations of the CCE and CSE models, which created inaccuracies, inadvertently increased the amount of time needed to use them. Specifically, manually checking the model outputs that turned out to be false: “We spend a lot of time because we don't want to assume there's an error and just dismiss talking about that young person.” (Early Intervention Practitioner) "I used to spend a lot of time methodically going through the 30 names, emailing people, and checking al
