Only 13 years ago in April 1998 Charles Hoffman, a CPA investigated how XML could be used for the reporting of business and financial information. By now many researchers are dealing with this topic. The high (practical) relevance of XBRL is emphasized by several laws and a large number of regulatory requirements stipulating the use of XBRL for business and financial reporting. Giving an overview of conducted research is complicated due to the rich diversity of XBRL. On top, traditional literature reviews are focusing on the performed research, not including any indication of the relevance of the investigated topic. We will go one step further and include discussed impacts and issues weighted by their occurrence in literature. Based on this approach the paper concludes that frequently mentioned impacts and issues of XBRL are not yet researched but in turn minor research questions are well investigated.

Die Evaluation beschreibt den Prozess, ein Forschungsergebnis hinsichtlich vorab definierter Ziele zu bewerten. Dieses Kapitel beinhaltet ein allgemeines und ubertragbares Vorgehen, mobile Assistenzsysteme in Bezug auf die Gebrauchstauglichkeit (Usability) anhand definierter Kriterien zu bewerten und iterativ zu verbessern. Zu diesem Zweck werden existierende Vorgehensmodelle, Normen und Standards sowie Best-Practices zu einem operationalisierbaren Leitfaden zusammengefasst.

ZusammenfassungDie zunehmende Durchdringung der Unternehmensabläufe mit IT-Systemen stellt den Prüfer vor neue Herausforderungen, bietet aber gleichzeitig auch neue Chancen zur Steigerung der Prüfungsqualität und -effizienz. Dies zeigt sich insbesondere an der Schnittstelle zwischen IT- und Prozessprüfung. Vor diesem Hintergrund stellt der Beitrag anhand eines Anwendungsbeispiels dar, in welcher Weise beide Prüfungsbereiche mit Process-Mining-Techniken integriert werden können, um zu einem umfassenden Prüfungsurteil auf Geschäftsprozessebene zu gelangen.

Maturity models are widespread used in several domains ranging from business processes to complete management frameworks like CMMI, ITIL or Cobit. In the paper on hand we develop a detailed maturity model for the management of segregation of duties in ERP systems. Our model includes several aspects starting with simple access rights management of individual systems and leading to comprehensive organizational aspects of multiple systems environments. Applying this model, organizations are enabled to improve compliance regarding access rights using a step by step approach. The approach described can also be used to assess existing segregation of duties processes of an organization in order to reveal further improvement opportunities.
