The audit schedule, including the sequence and timings of audit activities, such as opening meeting, document review, interviews, observations, closing meeting, etc.
The expected time and duration of each audit activity and location
The name and contact details of the auditee’s representative and other relevant parties
The allocation of appropriate resources to support the audit activities
The audit methods and techniques to be used, such as interviews, observations, sampling, etc.
The audit documents and records to be prepared and retained
