Audit Samples According to International Audit Standards

– valid audit results by means of methodic professional examination efforts –


Due to limited resources as well as a process-oriented examination procedure, fewer risk-oriented functional and case-by-case audits generally are conducted. For this reason alone, such examinations must be based on a qualitative intrinsic-value random sample. Practicing auditors often expect an increased effort due to the employment of risk-oriented random samples. Based on empiric examples, this particular consultancy module demonstrates and teaches that significant time savings can be achieved through the appropriate utilization of random-sample procedures. When such examinations are conducted in compliance with standards established by the Institute for Internal Auditors (IIA), among others, their results are accompanied by an increased audit quality. Within the framework of procedures covered in the course of instruction, participants are capable of applying the various random-sample techniques properly and conduct focused case-by-case audits at the same time.

In order to perform in accordance with both international and national audit standards – those of the IIA, the Institute of Public Auditors in Germany (Institut der Wirtschaftsprüfer in Deutschland = IDW), the International Standards on Auditing (ISAs), as well as those issued by the German Institute for Internal Auditing (Deutsches Institut für Interne Revision = DIIR) – it is necessary to conduct plausible and risk-oriented random-sample procedures.
