The global colour model (GCM) of QCD is a quark-gluon quantum field theory that very
successfully models QCD for low energy hadronic processes. An effective gluon correlator
models the interaction between quark currents. Functional integral calculus allows the GCM
to be hadronised. The dominant configuration of the hadronic functional integrals is
revealed to be the constituent quark effect, and is identical to the truncated quark
Dyson-Schwinger equations (tDSE). However the GCM shows that hadronic physics requires
processes that go beyond the tDSE. In this review examples of meson and nucleon processes
are given. The GCM also plays a pivotal role in showing how QCD may be related to many
other hadronic models.
