The NAO published its latest report on Crossrail on 9 July. The report highlights a number of positives: Crossrail Ltd and the sponsors are controlling costs and improving performance. The project is now hitting 90 per cent of the (revised) milestones.
However, the Benefits section (Section 4) makes interesting reading. Return on investment has been revised from £1.97 to £1.37 (for every £1 spent). The 2021 report highlights two further things about benefits management: 1) More clarity is needed around how the benefits are going to be realised; and 2) changes to working life as a result of Covid-19 and lockdown could remove the benefits originally forecast.
