7. Continuous Audit Analysis and Reporting System 4 th world continuous auditing and reporting symposium A. Nutz, E / University of AugsburgUniversity of Salford, April 18 th 2002 Pilot Engagements / Findings & Results Piloting took place in six European engagements (F, GER, CH, UK) Different size of engagements Different evaluation focus (audit efficiency respectively cooperation with third party users) Different scope and location of data mart Some of the pilot findings are: Within half of the pilots third party users joined the project Within these pilots no data capture had to be performed by the audit team as it was completely automated By providing modules of different complexity (query, OLAP, cockpits) more auditors with less technical skills are using analytics. Engagement teams were regarded as “the audit teams that are doing the better audit”

8. Continuous Audit Analysis and Reporting System 4 th world continuous auditing and reporting symposium A. Nutz, E / University of AugsburgUniversity of Salford, April 18 th 2002 Pilot Engagements / Findings & Results Pilot findings (cont.): Time savings were achieved by improved integration of modules. With standard audit routines time savings for analytic procedures are estimated to approx. 15 to 30 % of time spent for the current ad hoc approach. With standard audit routines integrated, AIS will be ‘THE SOLUTION’ and a competitive advantage. Especially the use of the OLAP-module improved the image as auditor.
