Due to the changes in the structures of public administrations within the European Union, business process management has moved into the focus of public decision makers. Several projects with established modelling and reorganisation approaches from the private sector show (Fraser et al. 2003; Seltsikas and Palkovits 2006), that the specific legal, personnel, and political conditions rule out a careless adoption of these approaches for the public sector. Especially, the high amount of public services requires an efficient representation of the entire process landscape in order to measure the overall reorganisation potential. Focusing on isolated processes only leads to small local improvements (Raster 1994). In this paper the PICTURE-approach for an integrated business process management in public administrations is presented. The PICTURE-method allows for an efficient documentation of the entire process landscape in a public administration and a detailed analysis of the resulting process descriptions.
