The systematics of strangeness enhancement is calculated using the HIJING andVENUS models and compared to recent data on $\,pp\,$, $\,pA\,$ and $\,AA\,$collisions at CERN/SPS energies ($200A\,\, GeV\,$). The HIJING model is used toperform a {\em linear} extrapolation from $pp$ to $AA$. VENUS is used toestimate the effects of final state cascading and possible non-conventionalproduction mechanisms. This comparison shows that the large enhancement ofstrangeness observed in $S+Au$ collisions, interpreted previously as possibleevidence for quark-gluon plasma formation, has its origins in non-equilibriumdynamics of few nucleon systems. % Strangeness enhancement %is therefore tracedback to the change in the production dynamics %from $pp$ to minimum bias $pS$and central $SS$ collisions. A factor of two enhancement of $\Lambda^{0}$ atmid-rapidity is indicated by recent $pS$ data, where on the average {\em one}projectile nucleon interacts with only {\em two} target nucleons. There appearsto be another factor of two enhancement in the light ion reaction $SS$ relativeto $pS$, when on the average only two projectile nucleons interact with twotarget ones.Comment: 29 pages, 8 figures in uuencoded postscript fil
