6.4 Identify risks

Risks threatens achievement of

identified process objectives.

Two elements for classification:

1. Impact

2. likelihood

6.7 What are management assertions?

Assertion – is a representation, explicit or implicit, that is embodied in the activities, financial transactions and information pertaining to the audited entity, used by the auditor in considering different types of potential deviations. In the context of compliance audit, the compliance assertion would mean that the entity, including responsible public sector officials, is acting in accordance with applicable authorities (crtteria). Assertions may be embodied in subject matter information presented by the audited entity or stated explicitly in a management representation letter.

6.9 Criteria ISSAI 4100 Chapter 6

The criteria, or the benchmarks against which the subject matter will be compared, must also be identified. In performing compliance audits, the identification of the criteria is an essential step in the audit planning process.

• Walk-though tests

• Direct observations

• Reperformance

17

Page 18: Presentation 6, Steps of system based auditing, Workshop on System-based auditing, Tirana, 10-12 Sept 2014_ENG

6.15 Test of control: when?
