The CAB establishes Working Groups (WGs) to accomplish tasks within its responsibilities which require more, or more specialized, preparation and discussion than can be accommodated within the framework of the twice-yearly CAB meetings. Terms of reference and membership are decided in advance for each WG.
WGs report regularly to the CAB, and any conclusions or decisions arising from their work are placed on the CAB’s agenda and decided there.
WGs are normally of limited duration and are disbanded by the CAB when no longer needed.
