Halden Logistics is a new audit client with a major ERP implementation during the year. The audit manager proposes to change the planned approach and rely less on testing controls and more on substantive procedures part-way through fieldwork because the new system proves unreliable. Which statement is consistent with ISA 300?

The auditor should update the overall strategy and audit plan as necessary during the audit, documenting significant changes and why they were made. Here, an unreliable ERP justifies shifting toward substantive procedures; the strategy is not fixed and resignation is not required.

ISA 300 requires the auditor to update and change the overall audit strategy and audit plan as necessary during the audit, for example due to unexpected events or results of procedures. Significant changes and the reasons for them are documented. It does not require resignation.
