  We consider a supersymmetric QCD with soft supersymmetry breaking terms as
the dynamics for the electroweak symmetry breaking. We find various advantages
compared to the non-supersymmetric models, such as a natural incorporation of
the dynamical top-quark mass generation (the topcolor mechanism), the existence
of a boson-pair condensation (the composite Higgs fields) and a large anomalous
dimension of the composite operator to cure the flavor-changing-neutral-current
and the S-parameter crises of the technicolor theories. The knowledge of the
weakly coupled description (the Seiberg duality) enables us to perform
perturbative computations in strongly coupled theories. Working in a large
flavor theory where perturbative calculations are reliable in the dual
description, one can find a stable vacuum with chiral symmetry breaking. The
top/bottom quarks and also the Higgsinos obtain masses through a dynamically
generated superpotential.
