We discuss the role of polarization measurements and scattering amplitudes for elastic nucleon-nucleon processes at high energy. The relative normalization of these amplitudes involves a {open_quote}{open_quote}leading order form factor{close_quote}{close_quote} which we determine empirically. These amplitudes provide an economical description of a large body of existing data and make some nontrivial predictions for spin observables. In particular, we have investigated cross sections and asymmetry data at large angles (including 90{degree} c.m.) and the fixed {vert_bar}{ital t}{vert_bar}, large {ital s} region, dominated by the three-gluon exchange mechanism. Our results indicate that polarization experiments can test basic QCD elements such as helicity conservation, wave function properties and the interplay between various interaction mechanisms. The significance of this analysis will be discussed in terms of specific polarization experiments, which can be performed at Fermilab and Brookhaven (RHIC, AGS). {copyright} {ital 1995 American Institute of Physics.}
