I received this from the top(well near the top)
Haddon-Cave Review Implementation Team (HCRIT)
HCRIT is an independent organisation that has been directed by the Second Permanent Under-Secretary (2ndPUS) to set specific requirements on the key airworthiness organisations to ensure they deliver the required outcomes, as agreed by the Secretary of State. Thereafter, the Team will be responsible for the coherent management of the requirements and for policing the implementation across Defence against agreed outputs and timelines, with the appropriate organisations managing any changes that are called for within their respective areas of responsibility. Specifically:
a. Inform 2ndPUS and the Nimrod Review Analysis Sub Group
(NRASG) on the impact and implications of the recommendations made by the Review.
b. Produce an implementation plan for the required work to be agreed by NRASG.
c. Deliver clear understanding throughout the implementation
across all air domain stakeholders of the impact of the Haddon-Cave Review recommendations.
d. Lead and champion implementation across the air environment, negotiating as necessary the reprioritisation of activity to meet the Department's commitment to the delivery of Haddon-Cave findings.
e. Orchestrate any follow on work that is required to facilitate or understand the recommendations.
f. Provide periodic updates to 2ndPUS on progress, identifying barriers to implementation that cannot be resolved.
g. Liaise with external agencies where recommendations have
implications to both the non-air environment and agencies outside of the Ministry of Defence.
I am not sure about f. identifying barriers to implementation that cannot be resolved.But it sounds like a good start.
