Since this Committee last reported on shared services, the Cabinet Office responded to concerns about its understanding of costs, benefits and value for money by updating its strategy’s case for change.20 The Cabinet Office has also created a dashboard designed to bring together cluster-held data on costs, benefits and delivery milestones.21 The Cabinet Office told us that 1,600 people consult the dashboard daily, and that the tool helps manage challenges to delivery.22 The dashboard relies on the Cabinet Office commissioning returns from clusters about their plans.23 As the Cabinet Office lacks the mandate to enforce these commissions, the quality and completeness of the data the dashboard contains varies significantly. For example, one part of the dashboard had missing data for 21 out of 64 returns. Incomplete data has undermined the dashboard’s usefulness to the Cabinet Office, including on understanding clusters’ performance and value for money.24
