E-Government, which has been a buzzword for all kinds of computer usage in the governmental context for several years, has started to become an ordinary way for public administrations to organise their work. Document and workflow management systems as well as process reorganisation(More)
In this paper a new process modelling method especially for public administrations is presented. With established generic process modelling methods reorganisation projects in this domain could only identify limited reorganization potential and just led to small local improvements [1]. Therefore, we have created the domain specific modelling approach(More)
As banks have realized the need to look on their business in a process-oriented way, they have been engaged in numerous business process optimization or even reengineering (BPR) projects in the last decade to make their organizations more efficient.

It is described whether and why the semantic building block-based approach reduces the variations in comparison to traditional modelling approaches. Our argumentation is grounded on the assumption that(More)
The Digital Divide is a matter of fact in most countries. For instance, senior citizens, citizens without employment, or citizens with low education utilise online services in a distinct way, often to a lesser extent.

To measure the impact of ICT-investments all processes of a public administration have to be taken into account. The PICTURE modelling method has been proposed as a way to efficiently(More)
Business Process Management (BPM) is a topic with growing relevance for businesses as well as public organisations. Until today, the analysis part of a BPM cycle is mostly done manually. Process modelling methods are not designed to allow for automated analysis. Our aim is to show that meaningful weakness patterns that support semi-automatic analysis of(More)
