N2 - We present the microscopic model for collective effects, built on string–string interactions (string shoving and rope hadronization), recently implemented in the PYTHIA8 and DIPSY event generators. Rope hadronization is shown to give a good description of strangeness enhancement across pp, pA and AA collision systems, while string shoving qualitatively describes the ridge observed in pp collisions.
