  I review in this presentation some aspects of phenomenology in High Energy
Physics which are related to recent and possibly future progress in lattice
QCD. In particular, I cover (i) the extraction of CKM matrix elements from B
physics, (ii) the determination of epsilon'/epsilon, as well as (iii) some
issues emerged in the physics of high energy jets produced in hadronic
collisions, where input from non-perturbative calculations would benefit our
capability to perform better theoretical predictions.
