Abstract: An event analysis system and method of analysing events are provided. The method comprises the steps of displaying event element icons in a user interface, updating the location of moved event element icons in the user interface, and determining an organization of the event elements based upon the location of the event element icons in the user interface. The event element icons represent event elements in an event or chain of event elements. The event element icons are movable in a coding panel of the user interface. The event analysis system comprises a presentation module for generating a user interface and event element icons for the user interface, a controller module for controlling the display of the user interface, and a data model module for holding a data structure representing the event elements and used to generate the event element icons.
