Towards automated financial process auditing: aggregation and visualization of process models Mueller-Wickop, Niels; Schultz, Martin; Gehrke, Nick; Nüttgens, Markus Nüttgens, Markus; Thomas, Oliver; Weber, Barbara Internal and external auditors face an enormous amount of financial entries in accounting information systems. For many reasons - like legal regulations - a process-oriented view of these entries is urgently needed in order to understand the way financial entries are produced in accounting information systems and to infer the underlying processes. Traditional modeling languages focus on processes but pay no regard to the financial value-flows. Furthermore, automated process retrieval approaches only reconstruct single process instances, which need to be aggregated for reasons of comprehensibility, simplification and clearness. The paper wants to close this gap and integrate the process with the accounting perspective followed by an aggregation of single process instances. As a result we present a visualization form capable of integrating the financial view with process flows. In this way, auditors are able to trace how balance sheet items have been produced in the system during the fiscal year.

Some guidelines for the conception of domain-specific modelling languages Frank, Ulrich Nüttgens, Markus; Thomas, Oliver; Weber, Barbara While the potential prospects of domain-specific modelling languages (DSML) are undisputed, the design of a DSML faces specific challenges that have raised only little attention so far. They relate to the boundaries between a DSML and corresponding models as well as to the question how specific a DSML should be. Addressing these challenges does not only contribute to the development of meta modelling methods, it also relates to judging the economics of a DSML. This paper suggests guidelines to support typical decisions that occur with the design of a DSML. They mainly concern the level of abstraction a potential language concept should be defined on. The guidelines are not intended to serve as recipes for design, but rather to improve the transparency of design decisions.

Applying soft systems methodology in enterprise architecture creation workshops Nakakawa, Agnes; Bommel, Patrick van; Proper, Erik Nüttgens, Markus; Thomas, Oliver; Weber, Barbara Lack of effective involvement of stakeholders is one of the main drawbacks of enterprise architecture initiatives. Ongoing attempts to overcome this involve using Collaboration Engineering to develop a collaboration process that enterprise architects can execute to facilitate collaborative sessions with stakeholders during architecture creation. However, a field study evaluation of this process revealed that it offered inadequate support for stirring vigorous and rigorous discussions during activities that required organizing and assessing problem or solution aspects that resulted from brainstorming activities. Since Soft Systems Methodology (SSM) helps to structure rational thinking about messy situations, its techniques can be adapted to supplement the design of the collaboration process with support for triggering discussions and creating a shared understanding and vision among stakeholders. This paper therefore presents a script that shows how this can be done, and discusses its evaluation in a real case.

Fast pattern matching in conceptual models – evaluating and extending a generic approach Dietrich, Hanns-Alexander; Steinhorst, Matthias; Becker, Jörg; Delfmann, Patrick Nüttgens, Markus; Thomas, Oliver; Weber, Barbara Identifying structural patterns in conceptual models serves a variety of purposes ranging from model comparison to model integration and exploration. Although there are a multitude of different approaches for particular modelling languages and application scenarios, the modelling community lacks an integrated approach suitable for conceptual models of arbitrary languages and domains. Therefore, a generic set-theory based pattern matching approach has recently been developed. To prove that this approach is beneficial in terms of performance, we conduct a statistically rigorous analysis of its runtime behaviour. We augment the original approach to include a caching mechanism that further increases performance. We are able to show that the original algorithm is able to identify arbitrary patterns within milliseconds. The caching extension further increases performance by up to fifty per cent given the model base and patterns we used.
