Understanding the deep origin of the electroweak symmetry breaking is at the core of some of the remaining fundamental questions in particle physics and cosmology. The discovery of the Standard-Model (SM) Higgs boson at the Large Hadron Collider (LHC) in 2012 has been a milestone achievement in this quest and made this connection even more compelling and intriguing. Since then, measuring its properties and characterising its role in electroweak symmetry breaking has become a key tool in the search for physics beyond the standard model. The CMS and ATLAS experiments at CERN play a fundamental role in making precision measurements of Higgs boson properties. As the dataset increases, the experimental collaborations are using ever increasing levels of sophistication to collect, analyse and interpret Higgs boson data, making use of advanced tool-kits like machine learning. As we move towards the high-luminosity (HL) running of the LHC, ensuring the continued success of the precision Higgs measurement programme poses a significant challenge that requires new experimental strategies to overcome. By exploiting the data that we will have in this way, Higgs boson precision measurements will complement existing searches for new particles, hopefully leading to discovery of new physics at the HL-LHC or beyond it.
