  Combining measurements of many production and decay channels of the observed
Higgs boson allows for the highest possible measurement precision for the
properties of the Higgs boson and its interactions. These combined measurements
are interpreted in various ways; specific scenarios of physics beyond the
Standard Model (SM) are tested, as well as a generic extension in the framework
of the Standard Model Effective Field Theory. The latest highlight results of
these measurements and their interpretations performed by the ATLAS
Collaboration are discussed.
