In addition to identifying areas of potential weakness, auditors must assess whether the system of internal controls is effective. To determine whether an internal control is effective, auditors use different procedures. For example, an auditor may test capital expenditure authorization by sampling the transactions and examining related documents. Other types of audits involve observations and investigations. The process is described in this article. If you are unsure of how to implement the necessary audit controls, it is important to seek professional advice.
Testing the effectiveness of controls requires careful planning. An audit should consider whether one control addresses the risk of misstatement that affects more than one assertion. The objective is to determine the impact of the control on the business, and the effectiveness of management’s assessment. While an audit should not focus on the dollar amount of a transaction, it is essential to test the controls to determine whether they are operating effectively. To determine if an audit is effective, auditors must consider the mix of procedures used by management.
Some tests are more effective than others. For example, an auditor may re-perform the same control that a client has performed. An auditor may verify whether an account exists, confirm its balance, or review relevant documentation. An audit may provide sufficient evidence of a control’s effectiveness if it is applied consistently. An audit may include more than one test, depending on the type of controls. Some tests are not applicable for all controls, while others require a combination of procedures.
The complexity of an organization’s operations and process will influence the risk level of an audit. Inherently occurring risks are more likely to occur if a company is more complex than it appears. For example, an auditor will need to assess the likelihood of a particular control failing due to incentives or pressures. This is especially true for companies with multiple levels of management. The risks assessment will identify the best controls and evaluate the effectiveness of those controls.
The process of testing the control is very important. During the audit, auditors will look at documents and re-perform client-performed controls. They will also verify that a company has implemented a variety of processes to protect itself. During the test, the auditor may need to examine all of these documents in detail. For example, an auditor may test the internal control of a bank account to assess the effectiveness of its loan-related security systems.
The testing procedure will include a number of procedures. The process may involve observation, inquiry, and examination of relevant documentation. It may also include re-performance of a control. An assessment of a control’s effectiveness is essential for the overall effectiveness of the audit. As a result, an assessment of the effectiveness of the controls will help an auditor determine whether the system is effective or not. It is essential to follow the procedures of the auditing firm and ensure that the controls have been correctly implemented.
