According to ISO 9001:2015, clause 8.4, an organization is required to control the processes, products and services provided by external providers, including those that affect the quality of the organization's own products and services. This includes determining the controls to be applied to the external provision of processes, products and services, as well as the information to be communicated to the external providers. The organization is also required to monitor, measure, and evaluate the performance of the external providers and retain documented information of these activities.
Therefore, in the scenario given, ABC Ltd is responsible for controlling the processes, products and services provided by Teak Ltd, as they affect the quality of ABC Ltd's own products and services. This means that ABC Ltd should have established criteria and methods for evaluating the performance of Teak Ltd, as well as documented information of the results of such evaluation. ABC Ltd should also have defined the supply arrangements with Teak Ltd, including the specifications, requirements, and verification activities related to the products and services provided by Teak Ltd.
Hence, the best options to describe how to plan the audit of the interrelationship with Teak Ltd during the Stage 2 audit at ABC Ltd are A and D, as they are aligned with the requirements of ISO 9001:2015, clause
8.4. The other options are either irrelevant or beyond the scope of the audit, as they do not pertain to the control of external provision by ABC Ltd.

The activities that are specifically required by ISO 17021-1 as part of third-party (Certification Body) surveillance audit processes are:
*Option A: Audit use of certification marks on marketing materials. This option is correct because ISO 17021-
1:2015 clause 9.6.2.2 requires the certification body to audit the client's use of marks and/or any other reference to certification, as applicable, to ensure conformity with the certification requirements.
*Option B: Review changes to the QMS since last visit. This option is correct because ISO 17021-1:2015 clause 9.6.2.2 requires the certification body to review any changes affecting the client's quality management system and its ability to continue to fulfil the requirements of the standard used for certification.
*Option C: Confirm effectiveness of internal audit and management review. This option is correct because ISO 17021-1:2015 clause 9.6.2.2 requires the certification body to confirm the continuing effectiveness of the client's quality management system, including the effectiveness of the internal audit and management review processes.
*Option F: Review the status of previously raised findings and audit effectiveness of any outstanding findings.
This option is correct because ISO 17021-1:2015 clause 9.6.2.2 requires the certification body to review the status of findings and any corrective actions taken by the client in response to previous audits, and to verify the effectiveness of the implemented corrective actions.
*Option H: Verify legal compliance. This option is correct because ISO 17021-1:2015 clause 9.6.2.2 requires the certification body to verify the client's compliance with applicable statutory and regulatory requirements related to the scope of certification.
*Option I: Handling of customer complaints since last visit. This option is correct because ISO 17021-1:2015 clause 9.6.2.2 requires the certification body to review the client's handling of customer complaints related to the certified activities since the last audit.
The following options are not correct:
*Option D: Complete a full document review of the quality management system. This option is not correct because ISO 17021-1:2015 clause 9.6.2.2 does not require the certification body to complete a full document review of the quality management system during surveillance audits. A full document review is only required during the initial certification audit or when there are significant changes to the quality management system or the certification requirements.
*Option E: Failing to meet financial responsibilities. This option is not correct because ISO 17021-1:2015 clause 9.6.2.2 does not require the certification body to audit the client's financial responsibilities during surveillance audits. The certification body may have contractual arrangements with the client regarding the payment of fees, but this is not part of the surveillance audit process.
*Option G: Review the calibration status of the instrumentation. This option is not correct because ISO 17021-
1:2015 clause 9.6.2.2 does not require the certification body to review the calibration status of the instrumentation during surveillance audits. The certification body may audit the client's monitoring and measuring resources as part of the quality management system requirements, but this is not a specific activity required by ISO 17021-1.
*Option J: Conduct a minimum number of annual surveillance audits during the certification period. This option is not correct because ISO 17021-1:2015 clause 9.6.2.2 does not require the certification body to conduct a minimum number of annual surveillance audits during the certification period. The certification body may determine the frequency and duration of surveillance audits based on the risk and performance of the client, but this is not a specific activity required by ISO 17021-1.

To complete the sequence, you can drag and drop the options to the appropriate blank section.
Here is a brief explanation of each stage:
Establishing the audit programme objectives: This is the first stage of the audit process, where the purpose, scope, and criteria of the audit programme are defined. The audit programme objectives should be aligned with the strategic direction and policies of the organization, and should address the needs and expectations of the interested parties12.
Determining and evaluating the audit programme risks and opportunities: This is the second stage of the audit process, where the factors that can affect the achievement of the audit programme objectives are identified and assessed. The audit programme risks and opportunities should consider the internal and external issues, the requirements and changes of the interested parties, and the results and feedback from previous audits12.
Establishing the audit programme: This is the third stage of the audit process, where the audit programme is designed and implemented. The audit programme should include the audit programme procedures, the audit programme resources, the audit methods and techniques, the audit frequency and schedule, and the audit programme performance indicators12.
Initiating the audit: This is the fourth stage of the audit process, where the audit is prepared and planned. The audit initiation involves selecting the audit team, establishing the contact with the auditee, defining the audit objectives, scope, and criteria, developing the audit plan, and conducting the document review123.
Preparing all audit activity: This is the fifth stage of the audit process, where the audit activities are organized and coordinated. The audit preparation involves assigning the audit tasks, communicating with the auditee and the audit team, arranging the logistics, preparing the working documents, and conducting the opening meeting123.
Conducting the audit activities: This is the sixth and final stage of the audit process, where the audit evidence is collected and evaluated. The audit conduct involves performing the audit activities, such as interviews, observations, document reviews, and tests, documenting the audit findings, preparing the audit conclusions, and conducting the closing meeting123.
