When understanding a client’s internal control, which issues should an auditor consider?

When understanding a client’s internal control, focusing on the design and implementation of the controls is crucial because it provides insight into how these controls operate within the organization. Effective internal controls are established through well-conceived design, which ensures they are capable of addressing the risks they are intended to mitigate. Additionally, understanding the implementation aspect allows the auditor to assess whether the controls are not only theoretically sound but also practically applied within the organization's processes.

This knowledge helps the auditor evaluate whether the controls can be relied upon to operate effectively and mitigate relevant risks, supporting the overall audit approach and risk assessment. Identifying weaknesses in the design or gaps in implementation can highlight potential areas of concern that may require additional scrutiny during the audit process, enabling a more focused evaluation of the client's internal control framework.
