Abstract	The First Long Shutdown (LS1) of the LHC and its Injector chain, which started in February 2013, was completed by the first quarter 2015. A huge number of activities have been performed; this paper reviews the process of the coordination of LS1 from the preparatory phase to the testing phase. The preparatory phase is a very important process: an accurate view of what is to be done, and what can be done is essential. But reality is always different, the differences between what was planned and what was done will be described. The paper will recall the coordination, reporting and decisional processes, highlighting points of success and points to be improved in terms of general coordination, in-situ coordination, safety coordination, logistics and resource management.
