Description	The Wheeler-DeWitt equation of Friedmann models with a massless scalar field is formulated with arbitrary factor ordering of the Hamiltonian constraint and a scalar product of wave functions is constructed. A critical energy of the matter field turns out to be necessary for a dynamical evolution of the wave function of the model. The introduction of a cosmological constant does not change the essential features.
