• Bodies should define at the outset how a programme is intended to be used in practice, and then continually develop their understanding of how it will operate as the programme develops. This should include considering what existing services and capabilities might be needed to support a new or enhanced service, and whether assumptions about the level of service to be introduced remain realistic. It should also include active engagement with whichever body will run the programme once in use.
• Wherever possible, entry into use should be carried out in stages to test and refine delivery and reduce the implementation risks of a larger improvement. However, bodies should develop arrangements for each stage in advance and in detail, including an understanding of what risks are being mitigated, and what is intended to be learned from each stage. Contingency arrangements for failure must also be in place regardless of whether or not a staged approach is adopted.
