7 We interviewed the senior management team at CCS, as well as the former chief executive and the former chairman. We also conducted interviews with the commercial directors of 15 government departments to get their opinion and insight into the functioning of CCS. We carried out a survey with these departments, focusing on their opinion of CCS's service offer, the value CCS adds and the savings reported by CCS.
8 For our process-mapping work, we carried out further analysis with the procurement teams of three departments (the Ministry of Defence, the Department for Communities and Local Government, and the Department for Transport). These departments transferred their spending in 2014-15. We chose them to provide a range of department size, function, and procurement activity. It provided evidence of departments' practical experience of working under the new arrangements and highlighted any performance issues.
9 We also discussed procurement with the Local Government Association and with the Welsh Audit Office. While these discussions could not represent the view of the wider public sector, they did provide useful context of the procurement landscape.
