The new event generation framework SHERPA, i.e.\ Simulation for High Energy Reactions of PArticles, will be presented. As the well established tools Pythia and Herwig, it aims at a full simulation of events at current and future high energy experiments. In its current form SHERPA is able to provide hadron level predictions for e.g.\ $e^+e^-$, $pp$ or $p(\bar p)$ collisions. Owing to the fact that SHERPA has its own matrix element generator, more tree-level processes, for instance SUSY particle productions, can be studied on the signal level. The capabilities of SHERPA shall be demonstrated by showing a selection of results. One of the striking features of SHERPA is the inclusion of the CKKW prescription to combine tree level multijet matrix elements with the subsequent parton showers. On that score recent results related to the production of weak vector bosons in association with jets at the Tevatron and the LHC will be discussed.
