Humans in order to create, share and improve knowledge about business processes need a common, readable and preferably visual notation. So far, there was a lot of effort put into visualisation of process definition (e.g. recently published Business Process Modelling Notation BPMN). We postulate to put equal stress on visualisation of process execution allowing process performers to understand the process history, its current state and possible future execution (potential consequences of the current decision). In our opinion, putting activity of interest in its visualised context makes the user knowledge more comprehensive and, consequently, increases productivity. In this paper, we define the process instance notation as an extension of BPMN. The underlying premise for such approach is the reuse of well defined and commonly accepted concepts (also their graphical form) from process definition level on the process execution level this again increases chances for the notation to be understandable. The prototype implementation is integrated within the ICONS knowledge management platform.
