The MB supervises the work of the Project as a set of formal activities.  It maintains the overall programme of work and all other planning data necessary to ensure the smooth execution of the work of the Project.  It provides quarterly progress and status reports to the OB. 

The MB endeavours to work by consensus but, if this is not achieved, the LCG Project Leader shall make decisions taking into account of the advice of the Board. 

The MB membership includes the WLCG Leader and deputies, representatives of the Tier-0 and Tier-1 Centres, the Computing Coordinator of each Experiment, the Chair(s) of the Technical Coordination Board, the WLCG service and operation coordination manager(s), and a Scientific Secretary and other members as decided from time to time by the Board.

MB meetings are held on a regular basis (usually monthly) on a Tuesday, at 16:00 and last 1-2 hours.
