The Cabinet Office said that each cluster has undertaken a lessons learned exercise. For example, the ‘Synergy’ cluster’s outline business case explicitly goes through the lessons learned and says how those are addressed in their programme.42 The Department for Work & Pensions noted that one of the lessons learned from previous shared services strategies was the lack of alignment around data configuration. Its cluster now has a common top 50 data sets, which align to the work that the Cabinet Office is doing.43 The overseas cluster launched its new service in November 2022 and the Cabinet Office highlighted the importance of sharing lessons from this experience with the other four clusters.44 36 Q 67; C&AG’s Report, para 12 37 Qq 32, 64, 67 38 Qq 64, 67, 88 39 Qq 31, 88–90 40 Qq 41, 53, 55, 88, 91 41 Committee of Public Accounts, Use of evaluation and modelling in government, Fourth Report of Session 2022–23, HC 254, May 2022; Committee of Public Accounts, Measuring and reporting public sector greenhouse gas emissions, Twenty-Third Report of Session 2022–23, HC 39, November 2022; and Committee of Public Accounts, Improving the Accounting Officer Assessment process, Twenty-Eighth Report of Session 2022–23, HC 43, November 2022. 42 Q 61 43 Q 12 44 Q 67 14 Government Shared Services
