Production of jets in association with W's and Z's at ATLAS

The study of final states with hadronic jets accompanying a W or Z boson is crucial at hadronic colliders. These processes provide an important test of perturbative QCD predictions and are the dominant background for many new physics searches. This talk summarizes the ATLAS prospects for the triggering, reconstruction and analysis of events with jets and leptonic decays of W and Z. Expectations for cross-section measurements with the first 1^-bf of data and estimate of the systematic uncertainties will be shown
