ONR can advise on this as follows.
The quarterly report for the period January - March 2009 to which you refer indicated that 'Exclusion Guidance was being developed'. The development of this quidance was further discussed in subsequent quarterly reports; eg April - June 2009, April - June 2010, and July - September 2010.
The development of the guidance also included publication of a discussion document on this topic entitled 'Discussion document on the Management of GDA Design Acceptance Confirmations Version 1 dated 30 April 2009' which we placed on our website for comment in May 2009.
Taking account of the comments received on this discussion document, the guidance was published in June 2010 and is entitled 'The management of GDA Outcomes'.
In this guidance the term 'exclusions' has been superseded by the term 'GDA Issue'.
