  While supersymmetric extensions of the Standard Model can be fully described
in terms of explicitly broken global supersymmetry, this description is only
effective. Once related to spontaneous breaking in a more fundamental theory,
the effective parameters translate to functions of two distinct scales, the
scale of spontaneous supersymmetry breaking and the scale of its mediation to
the standard-model fields. The scale dependence will be written explicitly and
the full spectrum of supersymmetry breaking operators which emerges will be
explored. It will be shown that, contrary to common lore, scale-dependent
operators can play an important role in determining the phenomenology. For
example, theories with low-energy supersymmetry breaking, such as gauge
mediation, may correspond to a scalar potential which is quite different than
in theories with high-energy supersymmetry breaking, such as gravity mediation.
As a concrete example, the Higgs mass prediction will be discussed in some
detail and its upper bound will be shown to be sensitive to the supersymmetry
breaking scale.
