Standard approaches to non-equilibrium dynamics in many-particle quantum systems such as the Quantum Boltzmann equation are based on perturbative truncations of the BBGKY hierarchy. In contrast, integrable systems (in the Euler scaling limit) are described by the recently developed theory of Generalised Hydrodynamics. I show how the two viewpoints can be explicitly related by developing a perturbative approach to integrability.
