Fault tree analysis has become an important tool for safety analysis of software and embedded systems. To address growing complexity component fault trees have been introduced. This paper focuses on the analysis of fault forests, an overlapping of multiple component fault trees. We present ideas to aid common cause analysis to effectively reduce the overall risk of top events within these forests. We try to visually aid the developer to find basic events which affect alarge number of top events, but also aid the risk reduction of one top event within the forest. We are not aware of any tool that supports common cause analysis.
