HMPPS lacks absolute assurance to meet revised prison delivery deadlines due to higher risks
Conclusion
We asked HMPPS whether it was certain that it could meet the revised deadline.32 HMPPS told us that while it could not give absolute assurance that it would deliver to schedule, it had built contingency into its timelines to allow for factors outside of its control. It explained that this included an assessment of how likely things were to go to plan, using learning from other government projects, which allows it to build in more contingency where it identifies a higher level of risk.33 However, HMPPS also indicated that the remaining delivery sites carried more risk as it had started with sites it considered would be more straightforward.34
