According to ISO 9001:2015, clause 7.2, an auditor shall have the competence to:
Understand the requirements of ISO 9001 and how they relate to the audit Understand the organization's quality management system and its processes Understand the applicable legal, regulatory, contractual and other requirements that affect the audit Understand the needs and expectations of interested parties other than customers Plan and conduct audits in accordance with ISO 19011 Evaluate audit evidence and draw appropriate conclusions Communicate audit findings effectively1 Therefore, knowledge of ISO 9001 requirements and ISO 19011 audit principles are essential for every member of an audit team auditing an ISO 9001 quality management system.

Comprehensive and Detailed In-Depth Explanation:
According to ISO 9001:2015, Clause 7.5.2 (Creating and Updating Documented Information), the criteria for reviewing documented information include:
* Content - The accuracy and relevance of the information.
* Format - Ensuring readability and proper structuring (e.g., language, versioning).
* Procedure for managing documented information - Ensuring control, access, and updates.
Other options, such as internal audit reports and client feedback, are important for overall QMS evaluation but are not the main criteria for reviewing documented information.

When an organization wishes to extend the scope of their current certification to include new services or activities, such as the printing and compilation of computer documentation packages, it requires an extension to the scope of the audit. This involves a formal application process with the certification body to ensure that the new activities are included in the audit plan and that the organization's quality management system encompasses these new processes12. References: = The answer is based on the ISO 9001 Auditing Practices Group guidance on scope and applicability, which outlines the need for a formal application process when there is a change in the scope of the quality management system that affects the certification1. Additionally, the UKAS guide on the extension to scope (ETS) process provides information on how changes to the scope, including the addition of new services, require a formal application2.

Comprehensive and Detailed In-Depth Explanation:
An audit's feasibility must be assessed using multiple factors, not just resource availability.
Clause References:
* ISO 19011:2018, Clause 5.3 - Establishing the Audit Program: Requires consideration of logistical, technical, and cooperation factors when assessing audit feasibility.
* ISO/IEC 17021-1:2015, Clause 9.1.3 - Determining Feasibility of the Audit: Requires evaluating more than just resources to ensure a successful audit.
Why is the Correct Answer B?
* Audit feasibility should consider:
* Availability of information (documents, records).
* Cooperation from the auditee.
* Operational conditions that might affect the audit.
* Scope and complexity of the QMS being audited.
* Resource availability alone is not enough to determine feasibility.
Why are the Other Options Incorrect?
* A (Top management determines feasibility) # Incorrect because feasibility is determined by the certification body, not the auditee.
* C (Resources alone are sufficient) # Incorrect because other key factors must be evaluated.
* D (Final authority lies with the audit leader) # Incorrect because ISO requires multiple factors to be considered, not just an auditor's decision.

In this scenario, the audit team leader must balance maintaining the integrity of the audit plan while considering the auditee's request. The two best responses allow for flexibility without compromising the audit's rigor:
A: I could audit the other laboratories virtually at the end of this audit: Virtual audits can be a valid option, especially in multi-site audits. ISO 9001:2015 does not prohibit virtual audits, and in certain situations, they are practical for reviewing documentation or observing operations remotely.
C: I could try to revise the audit programme to see if I can audit all laboratories: Revising the audit programme to accommodate additional site visits is a reasonable compromise. ISO 9001:2015 audits are based on risk and sampling, but the audit team leader has the flexibility to adjust the audit scope if it fits within the audit duration and resources.
The other options, such as extending the audit duration (B, F) or strictly adhering to the original plan (D, E), may not be practical or necessary. Revising the plan to audit all laboratories or using virtual auditing ensures that the audit remains efficient while addressing the organization's concerns.
