A process analysis system (1-300) processes event data describing real-world processes (1-100). The process analysis system performs the following acts: importing event instance data sets from an information management system (1-200), each set comprising one or more attributes describing an event instance in the real-world process (1-100); for each event instance, determining a corresponding process instance based on at least the attributes; determining event order attribute(s) for each imported event instance data set based on other event instance data sets corresponding to the same process instance; forming an analysis result set based on at least the event instance data sets and at least one first or second attribute; the client(s) presenting an analysis utilizing the analysis result set.
