How to improve operational efficiency?

At the end of 2009 we had 26 days of successful beam commissioning. Nevertheless, the period also revealed a number of possible weaknesses in various aspects of the LHC operation: procedures, tools, discipline, equipment and organisation, which were discussed during the talk What are the weak points of operation? by B. Goddard. This paper tries to quantize in which points the operational efficiency was low such we have a criterion to establish priorities, and how to improve them.
