We investigate the algebraic structure of supersymmetric Ward- and Slavnov-Taylor identities (STI) in field theories endowed with global supersymmetry. Developing diagrammatical methods for STI in supersymmetric gauge theories within a generalized BRST formalism is the key issue of this work. The above mentioned identities are essentially used as consistency checks for the implementation of phenomenological supersymmetric models of elementary particle physics in Monte Carlo simulations. We discuss the infrastructure necessary for generalizing the matrix element generator O'Mega to supersymmetric field theories.
