Title: The Challenges in Operating a Large High Energy Physics Experiment


This talk presents a walkthrough of the challenges in the evolution of one of the largest HEP experiment at LHC in the years to come: how to combine the needs of large production of good data for high statistics for discoveries; and the evolution of the apparatus to cope with the outperforming accelerator, its evolution as a High Luminosity LHC and the aspiration of the community to an increasingly better detector.
