The systematics of strangeness enhancement is calculated using the HIJING and
VENUS models and compared to recent data on pp, pA and AA
collisions at CERN/SPS energies (200AGeV). The HIJING model is used to
perform a {\em linear} extrapolation from pp to AA. VENUS is used to
estimate the effects of final state cascading and possible non-conventional
production mechanisms. This comparison shows that the large enhancement of
strangeness observed in S+Au collisions, interpreted previously as possible
evidence for quark-gluon plasma formation, has its origins in non-equilibrium
dynamics of few nucleon systems. % Strangeness enhancement %is therefore traced
back to the change in the production dynamics %from pp to minimum bias pS
and central SS collisions. A factor of two enhancement of Ξ0 at
mid-rapidity is indicated by recent pS data, where on the average {\em one}
projectile nucleon interacts with only {\em two} target nucleons. There appears
to be another factor of two enhancement in the light ion reaction SS relative
to pS, when on the average only two projectile nucleons interact with two
target ones.Comment: 29 pages, 8 figures in uuencoded postscript fil
