The recently proposed irreducible tensor formalism for hadron scattering and reactions is extended to pion production in NN collisions and a form akin to that of Wolfenstein for elastic NN scattering is derived together with exact partial wave expansions for the amplitudes. Explicit formulas are derived for spin observables relevant to differential as well as total cross section measurements employing a polarized beam on a polarized target which are currently of experimental interest
