ISO-9001-Lead-Auditor PECB QMS ISO 9001:2015 Lead Auditor Exam Free Practice Exam Questions (2025 Updated)

Comprehensive and Detailed In-Depth Explanation:

ISO 9001:2015, Clause 4.3 (Determining the Scope of the Quality Management System) states that when determining the QMS scope, an organization must consider:

External and internal issues (Clause 4.1)

The needs and expectations of interested parties (Clause 4.2)

The products and services provided by the organization

In the scenario, Bell only considered top management's input, which fails to address Clause 4.2 (interested parties' expectations)—such as customers, suppliers, and regulatory authorities.

A first-party audit is an internal audit conducted by auditors who are employed by the organization being audited but who have no vested interest in the audit results of the area being audited1. The purpose of a first-party audit is to assess the conformity of the organization’s quality management system to the requirements of ISO 9001 and to identify opportunities for improvement2. Therefore, the two auditors who would not participate in a first-party audit are:

•A. An auditor employed by an external consultancy organization: This auditor is not employed by the organization being audited, and therefore does not qualify as a first-party auditor. This auditor may be hired to conduct a second-party audit (if the external consultancy organization is a customer or supplier of the organization being audited) or a third-party audit (if the external consultancy organization is a certification body or registrar).

•F. An auditor from a customer: This auditor is not employed by the organization being audited, and therefore does not qualify as a first-party auditor. This auditor may be hired to conduct a second-party audit, as a customer is an interested party that has specific requirements for the organization being audited.

The other options are not correct, as they could participate in a first-party audit, as long as they are employed by the organization being audited and have no vested interest in the audit results of the area being audited:

•B. An auditor from an interested party: This auditor could be a first-party auditor, as long as the interested party is within the organization being audited. For example, an auditor from the finance department could audit the production department, as long as they are not involved in the production process or affected by its outcomes.

•C. An auditor trained in-house: This auditor could be a first-party auditor, as long as they are employed by the organization being audited and have no vested interest in the audit results of the area being audited. The source of the auditor’s training is not relevant for determining the type of audit, as long as the auditor is competent and qualified to perform the audit.

•D. An auditor trained in the IRCA scheme: This auditor could be a first-party auditor, as long as they are employed by the organization being audited and have no vested interest in the audit results of the area being audited. The IRCA scheme is a professional certification scheme for auditors of management systems, which provides recognition of the auditor’s competence and credibility3. However, being trained in the IRCA scheme does not determine the type of audit, as long as the auditor is competent and qualified to perform the audit.

•E. An auditor certified by IRCA: This auditor could be a first-party auditor, as long as they are employed by the organization being audited and have no vested interest in the audit results of the area being audited. Being certified by IRCA means that the auditor has met the requirements of the IRCA scheme and has demonstrated their competence and credibility as an auditor of management systems3. However, being certified by IRCA does not determine the type of audit, as long as the auditor is competent and qualified to perform the audit.

 First-party Management System audit → All members of an audited organisation

 Second-party Management System audit → Interested parties of an organisation

According to ISO 19011:2018 (Guidelines for Auditing Management Systems) and as reinforced in ISO 9001 Lead Auditor training materials, audit types are defined as:

First-party audit – conducted by the organization itself, or on its behalf (internal audit).✅ The audit client is all members of the audited organisation, because the audit is internal, involving all functional areas under the organization’s control.

Second-party audit – conducted by a customer or other person on behalf of a customer (external but not by a certification body).✅ The audit client includes interested parties of an organisation, such as customers who want to verify if their suppliers meet contractual or regulatory requirements.

These definitions are directly aligned with ISO 19011:2018, Clause 3.13 – Types of audits.

Why Other Options Are Incorrect:

Certification body / Accreditation body → These relate to third-party audits, not first or second.

Top management / Functions of an audited organisation → Refer to auditees or audit participants, not the audit client itself.

According to the ISO 9001:2015 document, the organisation must continually improve the suitability, adequacy, and effectiveness of the quality management system1. However, among the six options given, only effectiveness is directly mentioned as an aspect of the quality management system that must be continually improved. Therefore, C is one of the correct answers.

Efficiency, on the other hand, is not explicitly stated as an aspect of the quality management system that must be continually improved, but it is implied by the quality management principle of improvement, which states that successful organisations have an ongoing focus on improvement2. One of the key benefits of applying this principle is improving operational effectiveness and efficiency2. Therefore, E is another correct answer.

Suitability, adaptability, responsiveness, and applicability are not aspects of the quality management system that must be continually improved, according to the ISO 9001:2015 document. They may be related to the quality management system, but they are not the focus of continual improvement.

Therefore, the correct answer is C and E.

According to the ISO 9001:2015 standard, clause 8.4.1 requires organizations to ensure that externally provided processes, products and services conform to requirements. Controls must be applied to externally provided processes, products and services when:

The products and services are intended for incorporation into the organization’s own products and services.

They are provided directly to customers by the external provider on behalf of the organization.

A process, or part of a process, is provided by an external provider as a result of a decision by the organization.

In this scenario, the auditee has chosen a supplier to manufacture their own brand products based on their design drawings, supplier questionnaire and trial batches. This means that the supplier is providing a process (manufacturing) as a result of a decision by the organization (the auditee). Therefore, clause 8.4.1 applies to this situation.

Here is the correct matching of the activities with the responsible parties in the context of a second-party audit:

Define the audit scope: Customer

Develop the audit plan: Audit team leader

Respond to the audit findings: External provider

Conduct the audit: Audit team

This reflects the typical division of responsibilities in a second-party audit, where the customer (the party commissioning the audit) sets the scope, the audit team leader manages the planning, the external provider responds to findings, and the audit team carries out the audit.

Questions no: 1 Verified Answer: = C, D, E Comprehensive But Short Explanation: = Potential threats to impartiality in an audit context include familiarity (having a close relationship with the auditee), intimidation (being coerced or feeling pressured), and self-audit (auditing one’s own work). These factors can compromise the auditor’s objectivity and the audit’s integrity. References: = The information is based on the ISO 9001 Auditing Practices Group documents which discuss threats to auditor impartiality and how they may compromise an auditor’s objectivity123.

Comprehensive and Detailed In-Depth Explanation:

ISO 9001:2015 promotes the process approach, which allows organizations to structure their activities into interrelated processes. This approach helps ensure that processes effectively achieve intended results.

Clause 0.3.1 (Process Approach) states that "The application of the process approach in a quality management system enables understanding and consistency in meeting requirements, considering processes in terms of added value, and achieving effective process performance."

This aligns directly with option C, making it the correct answer. The other options are either partially correct or do not fully capture the purpose of the process approach:

Option A (Improvement based on interested parties) is a benefit but does not define the main goal.

Option B (Financial value) is not the primary focus of the process approach.

Option D (Reduction of resource consumption) may be an indirect benefit but is not a core objective.

 Clause Reference – ISO 9001:2015 Clause 8.6 (Release of Products and Services):

ISO 9001 requires that products and services are not released to the customer until:

All planned verification activities have been completed.

Acceptance criteria have been met.

Any necessary approvals have been obtained.

In this scenario:

The sacrificial anodes for Project DK were shipped before the galvanic efficiency test results were analyzed.

This constitutes a nonconformity against Clause 8.6 because the products were released without completing the required tests.

 Option Analysis:

A. A retrospective concession was not sought from the customer once the test results had been approved by the Quality Manager:Incorrect. While obtaining a concession might mitigate the situation, the nonconformity pertains to the process failure of releasing the products without completing required tests, not the absence of a concession.

B. Release of the product without acceptable test results has been accepted by the customer for Project DK:Incorrect. The customer was not informed before the release, and there is no indication that this was accepted beforehand. Furthermore, ISO 9001 requires planned processes to be followed, regardless of later acceptance.

C. Products for Project DK have been released before product approval through the quality control process:Correct. This description accurately reflects the nonconformity. The quality control process required test results to be analyzed and verified before release, which did not happen.

D. The untested product was not recalled until the galvanic efficiency of the anodes was verified:Incorrect. The issue is not about recalling the product but about releasing it without completing the required tests. Recalling the product is not mentioned in the scenario.

 Why C is Correct:

The nonconformity is a clear breach of Clause 8.6, where the products were released without meeting the planned verification requirements.

This demonstrates a failure in adhering to quality control processes, which is a critical aspect of ISO 9001 compliance.

 Key ISO 9001 Reference:

Clause 8.6: Products and services shall not be released to the customer until all planned activities (e.g., testing) have been satisfactorily completed, or the customer has approved the release with knowledge of deviations.

The purpose of conducting a document review is to determine the conformity of the system, as far as documented, with audit criteria and to gather information to support the audit activities. A document review is a systematic and objective examination of the documented information that is relevant to the audit objectives and scope. It can help the auditor to verify if the documented information is complete, accurate, consistent, and up-to-date. It can also help the auditor to identify any gaps, errors, or nonconformities in the documented information that may affect the audit findings or conclusions.

The other options are not correct because they do not reflect the true purpose of a document review. Option A describes the purpose of an audit report, which is to communicate the audit results and recommendations to the management and other interested parties. Option B describes the purpose of an audit plan, which is to define the scope, objectives, criteria, methods, resources, and schedule of an audit. Option C describes the purpose of an audit evidence report, which is to provide evidence of nonconformities or opportunities for improvement identified during an audit. Option D describes the purpose of an audit decision report, which is to justify or explain why certain decisions were made during an audit.

I hope this answer helps you understand why option F is correct and why options A-C-D are incorrect. If you want to learn more about ISO 9001 Lead Auditor exam questions and answers, you can check out some of these resources:

Comprehensive and Detailed In-Depth Explanation:

Toning down (or de-escalation) is a conflict resolution technique where:

Common agreements are emphasized to reduce tension.

Disagreements are addressed with a rational and constructive approach.

Option A describes compromise, and Option B describes authoritative resolution, which are different conflict resolution techniques.

Comprehensive and Detailed In-Depth Explanation:

The audit schedule provides a structured timeline of activities to be conducted during the audit.

Clause References:

ISO 19011:2018, Clause 6.4.2 – Preparing the Audit Plan:

Requires the development of an audit schedule, including the sequence and timing of activities.

ISO/IEC 17021-1:2015, Clause 9.1.3 – Audit Program:

Certification bodies must establish a schedule for conducting audits.

Why is the Correct Answer C?

The audit schedule ensures systematic execution of the audit by defining activities, responsible auditors, and timeframes.

A well-planned schedule improves efficiency and helps auditors cover all necessary areas within the given time.

Why are the Other Options Incorrect?

A (Audit objectives) → Define why the audit is conducted, not the schedule.

B (Audit criteria) → Define the standards and requirements to be evaluated, not the timeline.

D (Audit offer) → Refers to the initial proposal sent to the auditee, not the activity timeline.

Comprehensive and Detailed In-Depth Explanation:

According to ISO 19011:2018, Clause 6.4.9 (Audit Conclusions & Reporting):

One consolidated audit report should be drafted based on all team members’ findings.

Each auditor does not draft separate reports (B) unless explicitly required.

Thus, A is the correct answer.

Comprehensive and Detailed In-Depth Explanation:

Reliability in service quality refers to the consistent and dependable delivery of promised services.

ISO 9001:2015 emphasizes reliability through:

Clause 8.2.1 (Customer Communication) – Ensuring clarity in service commitments.

Clause 8.5.1 (Control of Service Provision) – Ensuring processes meet requirements consistently.

Other options do not fully define reliability:

Option A (Safe services) relates to safety, not reliability.

Option B (Readiness and goodwill) relates to responsiveness, not reliability.

Option D (Low cost) focuses on pricing, not quality.
