Non-Conformity Report:

ISO 9001 Clause Number

Nature of Problem

ISO 9001 Requirement That Has Not Been Fulfilled

6.1.1

Several risks and opportunities have not been determined.

"The organization shall consider the requirements referred to in 4.2 and determine the risks and opportunities that need to be addressed."

6.1.2 (a)

Actions to address risks and opportunities not planned.

"The organization shall plan actions to address risks and opportunities."

Step-by-Step Reasoning:

Clause 6.1.1 - Determining Risks and Opportunities:

Requirement: The organization must determine risks and opportunities that are relevant to its Quality Management System (QMS). This ensures that the QMS achieves intended results and prevents undesired effects.

Problem Identified: While some risks and opportunities were discussed, the organization did not perform a systematic evaluation of all risks (e.g., health and safety legislation changes, retiring trainers).

Clause 6.1.2 (a) - Planning Actions for Risks and Opportunities:

Requirement: The organization must plan actions to address identified risks and opportunities. These actions should be integrated into the QMS processes to ensure continuous improvement.

Problem Identified: The Quality Systems Manager confirmed that no plans were made to address the risks and opportunities because the Managing Director deemed it unnecessary. This violates the requirement to plan actions.

Correct Options Selected:

Clause 6.1.1 with the nature of the problem as: "Several risks and opportunities have not been determined."

Clause 6.1.2 (a) with the nature of the problem as: "Actions to address risks and opportunities not planned."

ISO 9001 Requirements Not Fulfilled:

For 6.1.1:"The organization shall consider the requirements referred to in 4.2 and determine the risks and opportunities that need to be addressed."

For 6.1.2 (a):"The organization shall plan actions to address risks and opportunities."

Comprehensive and Detailed In-Depth Explanation:

ISO 9001:2015 emphasizes the importance of communication as part of an effective Quality Management System (QMS).

Clause References:

Clause 7.4 (Communication): This requires organizations to establish what, when, with whom, and how communication should take place to ensure effectiveness.

Quality Management Principle – Engagement of People: Effective communication allows stakeholders (employees, suppliers, customers) to fully participate and contribute to quality objectives.

Why is the Correct Answer A?

Appropriate communication means ensuring that messages are clear, relevant, and accessible to the intended audience.

Different stakeholders (employees, customers, regulatory bodies, suppliers) may require different formats, languages, or media to ensure they fully understand and engage.

This aligns with ISO 9001:2015, which emphasizes that communication must be tailored to the needs of the recipient for maximum effectiveness.

Why are the Other Options Incorrect?

B (Timely responses) → Important but does not specifically refer to appropriateness in communication.

C (Communicating processes and assumptions to all interested parties) → Communication should be relevant; sharing all details might not be necessary or appropriate.

D (Only top management handling external communication) → Communication must be distributed across relevant functions, not restricted to leadership.

Understanding Clause 7.1.5.2 – Measurement Traceability:ISO 9001:2015 requires organizations to ensure that measuring equipment (e.g., spectrometers) is calibrated and traceable to recognized standards. The failure to maintain calibration within valid dates directly violates this clause and raises concerns about the reliability of the measurement results.

Root Cause of the Nonconformity:The organization failed to plan for the possibility that the calibration service provider (X-TECH) might become unavailable, leading to expired calibration. This indicates inadequate risk-based thinking, which is required under Clause 6.1 of ISO 9001:2015.

Option Analysis:

A. Select one sample for external lab analysis to use as an internal standard:Incorrect. While using an internal standard could provide short-term verification of results, this action does not address the root cause (failure to consider risks associated with external providers).

B. Look for a local company to provide this service:Incorrect. While finding a new local service provider resolves the immediate calibration issue, it does not address the risk of future provider unavailability.

C. Double-check one out of ten samples externally:Incorrect. This corrective action ensures some quality assurance for batch release but does not resolve the nonconformance related to expired calibration.

D. Add this issue to the external issue register, assess its associated risk, and plan action to address that risk:Correct. This approach directly addresses the root cause (failure to anticipate the calibration provider leaving) and ensures proper risk management. ISO 9001:2015 emphasizes risk-based thinking under Clause 6.1, requiring organizations to identify risks and opportunities and implement plans to mitigate them.

Why D is the Best Option:

By adding the issue to the external issue register, the organization ensures it is monitored and tracked.

Assessing the risk ensures proactive measures are in place for similar issues in the future.

Planning actions to address the risk ensures a sustainable solution is implemented, such as identifying multiple service providers or ensuring backup plans for calibration services.

ISO 9001 References:

Clause 6.1 (Actions to Address Risks and Opportunities): Requires organizations to consider risks and opportunities that could affect the intended results of the QMS.

Clause 7.1.5.2 (Measurement Traceability): Mandates that measuring equipment must be calibrated and traceable to ensure valid results.

Clause 10.2 (Nonconformity and Corrective Action): Requires organizations to determine the root cause of nonconformities and take actions to ensure they do not recur.

Comprehensive and Detailed Explanation From ISO 9001 / ISO 19011 Guidance:

ISO 9001:2015 requires audits to be planned and conducted objectively, but it refers auditors to ISO 19011 for detailed guidance on audit activities, including audit team meetings and preparation for closing meetings.

ISO 19011:2018 describes the purpose of the audit team meeting before the closing meeting as ensuring alignment, consistency, and clarity of audit conclusions and messages to the auditee.

Explanation of the selected tasks:

C. The audit team review any points raised by the auditee-nominated representative during the audit.

ISO 19011 requires the audit team to consider and evaluate information and concerns raised by the auditee to ensure audit findings are accurate, fair, and evidence-based before the closing meeting.

E. The audit team agrees on the audit opportunities for improvement to be presented to the supplier.

Before the closing meeting, the audit team must align on opportunities for improvement so that these are presented consistently and clearly, without contradiction between auditors.

F. The audit team agrees on the roles of each audit team member for the closing meeting.

ISO 19011 requires clear allocation of responsibilities within the audit team. Agreeing who will present findings, nonconformities, or conclusions is a normal and expected preparation activity.

G. The audit team leader writes all audit finding reports, taking into account the inputs provided by each auditor.

The audit team leader is responsible for consolidating audit inputs and ensuring consistency of reporting, even though individual auditors contribute evidence and findings.

H. Each audit team member completes the report of their individual findings.

ISO 19011 expects each auditor to document their findings and provide them to the audit team leader for consolidation into the final audit report.

J. The audit team agrees on the conformities and non-conformities to be included in the final audit report.

Before the closing meeting, the audit team must reach consensus on audit conclusions to ensure findings are clear, justified, and consistently communicated.

Explanation of why the other options are not selected:

A: Daily meetings with the auditee’s Quality Manager are not part of an internal audit team meeting and may compromise independence.

B: The final audit report is not completed and signed during the audit team meeting prior to the closing meeting.

D: Refusing to review corrective actions is inappropriate; however, corrective actions are normally reviewed after the audit, not during preparation for the closing meeting.

I: Informing the Procurement Manager is an administrative action, not a task of the audit team meeting.

ISO-aligned conclusion:

An audit team meeting prior to the closing meeting focuses on alignment, consolidation of findings, agreement on conclusions, and preparation for clear communication. The six correct tasks are therefore C, E, F, G, H, and J.

Comprehensive and Detailed In-Depth Explanation:

According to ISO 17021-1:2015 (Conformity Assessment – Requirements for Certification Bodies), Clause 9.3.1.2, the Stage 1 Audit typically consumes around 30% of the total audit time.

This time is allocated to:

Reviewing documented information.

Assessing the readiness for Stage 2.

Identifying potential nonconformities.

A 20% allocation (Answer A) is too low, and 40% (Answer C) is excessive, as the majority of the audit should be spent on Stage 2 (on-site verification).

Comprehensive and Detailed In-Depth Explanation:

Certification bodies must remain independent and impartial. If a certification body (ABC-CERT) provides consulting services to an organization through its subsidiary (Consultancy ABC), it cannot later certify the same organization.

Clause References:

ISO/IEC 17021-1:2015, Clause 5.2.5 – Impartiality Requirements:

A certification body must not certify an organization to which it has provided consultancy services.

ISO/IEC 17021-1:2015, Clause 5.2.6:

Subsidiaries of certification bodies must not provide consulting services to prevent conflicts of interest.

Why is the Correct Answer C?

Certifying a client after providing consultancy creates a conflict of interest and violates ISO/IEC 17021-1:2015 impartiality rules.

The certification body (ABC-CERT) and consultancy firm (Consultancy ABC) are related entities, making it impossible to remain objective and independent.

Why are the Other Options Incorrect?

A (Waiting two years) → ISO does not specify a time frame; the issue is impartiality, not just time.

B (Signing an agreement to ensure objectivity) → Conflicts of interest cannot be resolved through an agreement; independence is required.

According to ISO 9001:2015, clause 9.1.1, the organization is required to determine what needs to be monitored and measured, the methods for monitoring, measurement, analysis and evaluation, as applicable, to ensure valid results, and when the monitoring and measuring shall be performed. The organization is also required to retain appropriate documented information as evidence of the results.

Therefore, in the scenario given, the organization should have planned for monitoring and measuring the billet temperature, as it is a critical factor for the quality of the product and the process. The organization should also have established a procedure that provides instruction in taking billet temperature, using the pyrometer or other suitable methods, to ensure consistency and accuracy. The organization should also have performed periodic analysis of the results of temperature checks, to identify trends, problems, and opportunities for improvement.

Hence, the options that would provide evidence of conformance with clause 9.1.1 of ISO 9001 are A, E, and F, as they are aligned with the requirements of the clause. The other options are either irrelevant or not directly related to clause 9.1.1, as they do not pertain to the monitoring and measurement of the billet temperature.

Comprehensive and Detailed In-Depth Explanation:

ISO 9001:2015 requires collaboration between the auditee (TD Advertising), the certification body, and the audit leader when making changes to audit scope.

Clause References:

ISO/IEC 17021-1:2015, Clause 9.2.3 – Conducting the Audit: Any change in audit scope must be agreed upon by all parties before proceeding.

Why is the Correct Answer C?

TD cannot unilaterally change the scope without agreement from the certification body and audit leader.

The certification body must ensure the scope remains relevant and that resources are allocated properly.

Why are the Other Options Incorrect?

A (Anne cannot withdraw) → Incorrect, Anne CAN withdraw if the changes make the audit unfeasible, but she must consult with the certification body first.

B (TD cannot change the scope) → Incorrect, scope changes are allowed but must be formally approved.

D (Anne has full authority to reject scope changes) → Incorrect, scope changes require mutual agreement among all parties.

Here is the correct matching of actions to the statements in the context of leading the internal audit:

If practicablecarry out a formal opening meeting

You should notaudit production (as you are a supervisor in that area, and this would compromise audit objectivity)

You need notchange the audit team (unless there is a specific reason, such as conflict of interest)

You mustraise audit findings if necessary (this is a key responsibility of an auditor when nonconformities are found)

You must notsend the audit report to the Quality Manager (the audit report must be reviewed first; it is typically part of the internal audit process to go through necessary channels before final submission)

You shouldsend the audit report to the Quality Manager (after appropriate reviews and approvals)

This reflects key principles of conducting an internal audit according to ISO 9001:2015, ensuring objectivity, proper documentation, and clear reporting procedures.

Comprehensive and Detailed In-Depth Explanation:

According to ISO 19011:2018, Clause 5.2 (Audit Program Management):

The audit committee is responsible for establishing the internal audit program.

The audit schedule (A) is determined within the program, but it is not the main role of the committee.

Thus, C is the correct answer.

Comprehensive and Detailed In-Depth Explanation:

As per ISO 9001:2015, Clause 10.2 (Nonconformity and Corrective Action), all identified nonconformities, including minor ones, must be documented and communicated to the auditee.

Minor nonconformities can lead to major issues if left unaddressed. The auditor must inform the organization before moving to the next audit phase so that corrective actions can be taken. Clause 9.2.2 (Internal Audit) states that audit findings should be reported without undue delay.

Since Li Na did not report the minor nonconformities immediately, her decision was incorrect. Minor nonconformities should always be documented and communicated before proceeding to the next phase.

ISO 9001:2015 requires audits to be planned and conducted to ensure the quality management system conforms to requirements and is effectively implemented. While ISO 9001 sets the requirement, it explicitly refers auditors to ISO 19011 for detailed guidance on audit planning and execution.

ISO 9001:2015, Clause 9.2.2 (NOTE) states that guidance for auditing management systems is provided in ISO 19011 .

Based on ISO 19011:2018 (Clause 6.3 – Initiating and preparing for the audit), the audit team leader is responsible for finalising key planning issues before documenting the audit plan, especially for multi-site and multi-country audits.

Explanation of the selected options:

A. Arrangement of translation of the audit report

ISO 19011 requires consideration of communication and language arrangements during audit preparation. Where sites are located in different countries, potential language difficulties must be addressed during planning, including translation needs for reports and communications.

C. Structuring the audit plan to account for audit trails

ISO 19011 requires audits to follow audit trails across processes, functions, and interfaces. The audit plan must be structured to allow logical progression through interrelated processes, which must be decided before the plan is documented.

D. Determining available IT infrastructure for remote participation

ISO 19011 allows the use of remote auditing techniques. When audit team members are located in different countries, the audit team leader must confirm the availability of IT infrastructure to support remote participation in opening and closing meetings as part of audit planning.

E. Considering processes not operating at the time of the audit

ISO 19011 requires the audit team leader to consider process availability. If some processes are not operating during the audit period, alternative audit methods (such as records review or rescheduling) must be planned in advance and reflected in the audit plan.

Explanation of why the other options are not selected:

B: ISO 19011 requires identification of roles and functions to be audited, not specific names, at the audit planning stage.

F: Moderation or grading of nonconformities is performed after audit findings are raised, not during audit planning.

G: Post-audit communication arrangements are addressed during reporting and follow-up activities, not before documenting the audit plan.

H: Follow-up audits are planned only if required after audit results are known, not during initial audit planning.

Comprehensive and Detailed In-Depth Explanation:

ISO 9001:2015 requires organizations to identify and control nonconforming outputs to prevent unintended use or delivery.

Clause References:

Clause 8.7 (Control of Nonconforming Outputs): Organizations must ensure that nonconforming outputs are identified and controlled to prevent unintended use or delivery.

Clause 10.2 (Nonconformity and Corrective Action): Requires organizations to take appropriate actions when nonconformities are found, including during or after service provision.

Why is the Correct Answer C?

If nonconforming products or services are identified after delivery or during service, organizations must take corrective actions to protect customers and stakeholders.

Actions may include recalls, rework, customer notifications, compensation, or process improvements.

This approach aligns with ISO 9001:2015, ensuring that products/services consistently meet requirements.

Why are the Other Options Incorrect?

A (Retaining documentation only) → While documentation is required, it alone does not ensure proper handling of nonconforming outputs.

B (Verifying conformity before correction) → While verification is good practice, ISO 9001 prioritizes corrective action over mere verification.

D (Allowing employees to handle nonconformities without structure) → ISO 9001 requires documented procedures for handling nonconformities (Clause 8.7).

ISO 9001:2015 requires organisations to take corrective action to eliminate the cause of a nonconformity in order to prevent recurrence, not merely to contain or correct individual instances.

Relevant ISO 9001 requirements

Clause 10.2.1 – Nonconformity and corrective actionThe organisation shall react to the nonconformity, evaluate the need for action to eliminate the cause(s), and implement actions to prevent recurrence.

Clause 8.5.1 – Control of production and service provisionProduction shall be carried out under controlled conditions, including suitable infrastructure and environmental conditions.

Explanation of the correct corrective actions:

D. Redesign the factory layout to better handle finished products

This addresses a systemic cause of the problem by improving how finished products are handled after ejection, reducing the likelihood of products falling to the floor. This is a true corrective action aligned with Clause 10.2.

E. Set up a system of regular inspection of the floor condition

The dirty and wet floor is a contributing cause to product rejection. Establishing regular inspection and maintenance of floor conditions addresses the environmental conditions for production, as required by Clause 8.5.1, and helps prevent recurrence.

G. Install guides at the point of ejection to better direct products into the baskets

This directly eliminates the root cause of products missing the collection baskets by improving equipment control. It is an effective corrective action that prevents the nonconformity from happening again.

Explanation of why the other options are not corrective actions:

A: Recording nonconformities is detection, not prevention.

B: Placing a worker is a temporary containment action, not elimination of the root cause.

C: Asking customers to accept dirty products is unacceptable and contrary to ISO 9001.

F: Awareness alone does not remove the cause of the problem.

H: Cleaning products before release is correction, not corrective action, and does not prevent recurrence.

ISO-aligned conclusion:

Corrective actions must remove the root causes of nonconformities. In this scenario, improving product handling design, controlling environmental conditions, and modifying equipment to ensure correct ejection are the only actions that effectively prevent the recurrence of rejected products. Therefore, the correct answers are D, E and G.

Comprehensive and Detailed In-Depth Explanation:

Before accepting an audit, the certification body must assess the integrity of the auditee and the nature of its operations to ensure compliance feasibility.

Clause References:

ISO/IEC 17021-1:2015, Clause 9.1.2 – Audit Planning:

The certification body must review the auditee’s background, reputation, and operational complexity before accepting the audit.

Why is the Correct Answer C?

The auditee’s integrity and reputation impact the credibility of certification.

The nature of operations determines audit complexity and resource allocation.

Why are the Other Options Incorrect?

A (Integrity and reputation only) → Correct but incomplete; nature of operations is equally important.

B (Nature of operations only) → Integrity is also a factor, not just operations.

D (No previous major nonconformities required) → Auditees with past major nonconformities can still be audited if corrective actions are taken.
