This workflow strictly adheres to the "Process for collecting and verifying information" outlined in the ISO 19011 standard.

1. Audit Evidence (Step 3): Information gathered through sampling (Step 2) is verified and becomes audit evidence.
2. Evaluate against audit criteria (Step 4): The auditor must compare the gathered evidence against the specific requirements (criteria) to determine conformity or nonconformity.
3. Audit Findings (Step 5): The result of this evaluation is the generation of audit findings (e.g., conformities or nonconformities).
4. Review (Step 6): Before finalizing the conclusions, the findings are reviewed (often with the auditee to acknowledge accuracy) to support the final Audit conclusions (Step 7).

ISO 19011:2018 Guidelines for auditing management systems.

Figure 2: "Process for collecting and verifying information" (Visual flowchart matching the question).

Section 6.4.7: "Generating audit findings" (Describes the evaluation of evidence against criteria to determine findings).

Section 6.4.8: "Determining audit conclusions" (describes the review process leading to conclusions).

This sequence follows the logical progression of ISO 14001:2015 Clause 6.1.2. The process begins with the identification phase (Steps 1 & 2), where the organization identifies its environmental impacts and the associated environmental aspects (causes). To evaluate these, the organization must first establish criteria (Step 3) for significance. Using these criteria, the organization performs an evaluation to determine which impacts are significant (Step 4). Finally, the aspects associated with these significant impacts are designated as significant environmental aspects (Step 5). This final output is the necessary prerequisite for Clause 6.1.4, where the organization plans actions (Step 6) to address them.

ISO 14001:2015, Clause 6.1.2 (Environmental aspects): "The organization shall determine the environmental aspects... and their associated environmental impacts... The organization shall determine those aspects that have or can have a significant environmental impact."

ISO 14001:2015, Clause 6.1.4 (Planning action): "The organization shall plan: a) actions to address its: 1) significant environmental aspects..."

ISO 14004:2016, Clause 6.1.2.5 (Determining significant environmental aspects): Provides guidance on establishing criteria (environmental concerns, legal requirements) to determine significance.

ISO 14001:2015, Annex A.6.1.2: Explains the relationship between aspects, impacts, and the criteria used to determine significance.

The client's request constitutes a significant change to the audit scope, which was defined and agreed upon during the audit planning phase (typically following Stage 1). A lead auditor does not have the authority to unilaterally approve such a change on-site at the start of a Stage 2 audit. This request is formally known as an "extension to scope." The certification body must follow a defined process to evaluate the request, which may involve a new application, a contract review, allocation of additional audit time and resources, and ensuring the audit team has the necessary competence for the new activities. Option B correctly and professionally communicates this procedural requirement to the client.

A. This response is unprofessional and focuses only on a logistical constraint (time), failing to address the fundamental procedural issue of formally managing a scope extension.
C. While the audit programme manager is the correct contact, this response is incomplete. It fails to first explain to the client why this is necessary, which is a key part of the auditor's communication role.
D. This suggests an invalid audit method. To properly audit the environmental aspects and impacts of the installation process, it must be observed at the actual work site, not simulated in a meeting room.

1. ISO/IEC 17021-1:2015, Conformity assessment — Requirements for bodies providing audit and certification of management systems — Part 1: Requirements.

Clause 9.1.2, Application review: The certification body must conduct a review of the application and supplementary information to establish, among other things, the scope of certification. A request to extend the scope would require a similar formal review to assess its impact on the audit programme, time, and resources.

Clause 9.2.2.1, General (Audit Plan): "The audit team leader shall be responsible for the preparation of the audit plan..." The plan is based on the agreed-upon scope. A last-minute change invalidates the existing plan and cannot be accommodated without following the certification body's formal process for scope modification.

2. ISO 19011:2018, Guidelines for auditing management systems.

Clause 6.2.2, Defining the audit objectives, scope and criteria: This clause states that "The audit scope should be consistent with the audit programme and audit objectives." The lead auditor's role is to conduct the audit within the agreed scope, not to redefine it during the audit itself. Any changes must be managed through the individual responsible for managing the audit programme.

3. Sari, M., & Susanto, N. (2020). The Role of Lead Auditor in Management System Certification Audit Based on ISO/IEC 17021-1. IOP Conference Series: Materials Science and Engineering, 852, 012143.

This publication discusses the responsibilities of the lead auditor, emphasizing adherence to the certification body's procedures and the requirements of ISO/IEC 17021-1. It reinforces that managing the certification scope and client contracts is a function of the certification body's management (i.e., the audit programme manager), not a decision to be made independently by the auditor in the field. (DOI: https://doi.org/10.1088/1757-899X/852/1/012143, Section 3.2, "Audit Activities").

Audit criteria are the set of policies, procedures, or requirements used as a reference against which objective evidence is compared during an audit. According to ISO 19011:2018, these criteria can include applicable policies, procedures, standards, legal requirements, management system requirements, contractual requirements, or codes of conduct. Therefore, the organization's own Management policy (specifically the environmental policy in this context) and the ISO 14001 requirements are fundamental components of the audit criteria for an environmental management system (EMS) audit. The auditor evaluates whether the organization's practices conform to both the international standard and its own stated commitments.

B. Financial objectives: These are generally outside the scope of an ISO 14001 audit unless they are explicitly linked to an environmental objective defined within the EMS.
C. Nonconformity report: This is an output or result of the audit process, documenting where evidence shows a failure to meet the audit criteria. It is not a criterion itself.
D. Audit conclusions: These are the final outcomes of the audit, determined by the audit team after evaluating the audit findings against the audit objectives.
E. Auditor competence: This is a necessary attribute of the audit team and a requirement for conducting the audit, not a criterion against which the auditee's system is measured.

1. International Organization for Standardization. (2018). ISO 19011:2018 Guidelines for auditing management systems. Clause 3.7, "Terms and definitions," defines audit criteria as the "set of policies, procedures or requirements used as a reference against which objective evidence is compared."

2. International Organization for Standardization. (2015). ISO 14001:2015 Environmental management systems — Requirements with guidance for use. Clause 5.2, "Environmental policy," requires top management to establish an environmental policy that is used as a framework for setting objectives. This policy becomes a key audit criterion. The standard as a whole constitutes the primary set of requirements.

3. Sârbu, R., & Bârsan-Pipu, N. (2018). The Role of Internal Audit in the Environmental Management System. Ovidius University Annals, Economic Sciences Series, XVIII(1), 538-542. This paper discusses how internal audits verify conformity with planned arrangements, including the requirements of the ISO 14001 standard and the organization's own established EMS requirements (such as its policy).

4. University of North Carolina at Chapel Hill. (n.d.). ENVR 675: Environmental Management and Policy Course Syllabus. Gillings School of Global Public Health. Course materials typically describe environmental audits as a systematic process of evaluating an organization's performance against a set of criteria, which explicitly include regulations, standards like ISO 14001, and corporate policies.

According to ISO 19011:2018, Guidelines for auditing management systems, the process of "conducting audit activities" (Clause 6.4) includes the formal execution of the audit. This phase begins with the opening meeting to confirm the audit plan with the auditee (Clause 6.4.3). It encompasses the collection and verification of information, generating audit findings, and culminates in preparing the audit conclusions (Clause 6.4.9) before the closing meeting. These conclusions form the basis of the audit report. Therefore, holding the opening meeting and determining the audit conclusion are integral parts of this specific phase.

B. Assign work to the audit team: This is part of "Preparing audit activities" (ISO 19011:2018, Clause 6.3.3), which occurs before the on-site audit execution begins.
C. Distribute the audit report: This is a distinct, subsequent phase, "Preparing and distributing the audit report" (ISO 19011:2018, Clause 6.5), which follows the conclusion of on-site activities.
D. Verify corrective action effectiveness: This is part of "Conducting audit follow-up" (ISO 19011:2018, Clause 6.7), which may occur long after the audit itself is completed.
E. Determine audit feasibility: This is an initial step performed during the "Initiating the audit" phase (ISO 19011:2018, Clause 6.2.3) to ensure the audit can be conducted.

1. International Organization for Standardization (ISO). (2018). ISO 19011:2018, Guidelines for auditing management systems.

Section 6.4, "Conducting audit activities," outlines the entire phase.

Section 6.4.3, "Conducting the opening meeting," explicitly lists this as a step within conducting the audit.

Section 6.4.9, "Preparing audit conclusions," specifies this as the final step within the conducting phase, before the closing meeting.

Incorrect options are addressed in separate clauses: 6.2.3 (E), 6.3.3 (B), 6.5 (C), and 6.7 (D).

Day 3: Conducting an ISO 14001 audit. This module details the steps of audit execution as per ISO 19011, Clause 6.4, covering the opening meeting, communication, evidence collection, generating findings, and formulating conclusions. It clearly distinguishes these activities from the preparation (Day 2) and reporting/follow-up (Day 4) phases.

Slide 15, "The Audit Process," presents a flowchart based on ISO 19011. It clearly places "Opening Meeting" and "Review Findings & Prepare Conclusions" within the "On-site Audit" (Conducting) phase, while activities like "Assign Team" are in "Preparation," and "Issue Report" and "Follow-up" are subsequent stages.

The purpose of an ISO 14001 Stage 1 audit is to conduct a readiness review of the organization's Environmental Management System (EMS). This audit primarily focuses on the documented system design and planning to determine if it meets the standard's requirements and is ready for the Stage 2 implementation audit. An organization's financial statement (C) is not required as it falls outside the scope of an EMS audit. While the management review record (D) is mandatory documented information for a functioning EMS, its detailed review is typically a focus of the Stage 2 audit, which verifies implementation and effectiveness. The Stage 1 audit confirms that the process for management review is planned and in place, but the record itself may not yet be available or complete for a newly implemented system.

A. A list of planned emergency responses is a core requirement of Clause 8.2 (Emergency preparedness and response) and is essential for reviewing the system's design in Stage 1.
B. An internal audit schedule is necessary to demonstrate that the internal audit program (Clause 9.2) has been established and planned, a key readiness checkpoint for Stage 1.
E. Documented information on the environmental objectives is a fundamental requirement (Clause 6.2.1) that defines the EMS's goals and is a primary focus of the Stage 1 documentation review.
F. The list of environmental aspects is a foundational document for the entire EMS (Clause 6.1.2) and must be reviewed during Stage 1 to understand the system's scope and basis.

1. ISO/IEC 17021-1:2015, Conformity assessment — Requirements for bodies providing audit and certification of management systems — Part 1: Requirements.

Section 9.3.1.2.1 outlines the objectives of a Stage 1 audit. It emphasizes reviewing the client's documented information and evaluating if processes like internal audits and management reviews are "planned and performed" to substantiate readiness for Stage 2. This distinguishes the Stage 1 focus on planning from the Stage 2 focus on the results and records of performance.

2. ISO 14001:2015, Environmental management systems — Requirements with guidance for use.

Clauses 6.1.2, 6.2.1, 8.2, 9.2.2, and 9.3 specify the requirements for documented information related to environmental aspects, objectives, emergency response, internal audit programs, and management review results, respectively. The standard requires these to exist in a mature EMS, but audit practice, as defined in ISO/IEC 17021-1, separates the review of plans (Stage 1) from the review of implementation records (Stage 2).

3. Sârbu, R. (2017). The necessary steps for the certification of the environmental management system according to ISO 14001:2015. MATEC Web of Conferences, 121, 04013.

Section 3, Paragraph 2 describes the two-stage certification process. It states, "The first stage audit... is a review of the documentation... The purpose of this audit is to check if the requirements of the standard are documented..." This academic description supports that Stage 1 is primarily a review of the documented design (plans, procedures, objectives) rather than implementation records like management review outputs. (DOI: https://doi.org/10.1051/matecconf/201712104013)

The ISO 14001:2015 standard is explicitly based on the Plan-Do-Check-Act (PDCA) model. The 'Check' stage corresponds directly to Clause 9, "Performance evaluation." This clause comprises three sub-clauses: 9.1 Monitoring, measurement, analysis and evaluation; 9.2 Internal audit; and 9.3 Management review. Therefore, 'Monitoring performance' (F) and 'Management review' (E) are two fundamental elements that fall squarely within the 'Check' stage. These processes are designed to evaluate the environmental performance and the overall effectiveness of the Environmental Management System (EMS) against the organization's policies, objectives, and other criteria.

A. Control of the processes: This is part of Clause 8, "Operation," which belongs to the 'Do' stage where plans are implemented and executed.
B. Environmental policy: This is a core component of Clause 5, "Leadership," which is a foundational part of the 'Plan' stage.
C. Improvement: This is the title and subject of Clause 10, which represents the 'Act' stage, where actions are taken to enhance performance.
D. Nonconformities: The process for managing nonconformities and implementing corrective actions is detailed in Clause 10.2, which is part of the 'Act' stage.

1. International Organization for Standardization (ISO). (2015). ISO 14001:2015 Environmental management systems — Requirements with guidance for use.

Section 0.3, Plan-Do-Check-Act model, Figure 1: This figure explicitly maps the clauses of the standard to the PDCA cycle. It shows Clause 9, "Performance evaluation," as the 'Check' stage and Clause 10, "Improvement," as the 'Act' stage.

Clause 9, Performance evaluation: The text of this clause details the requirements for monitoring, measurement, analysis, evaluation, internal audit, and management review, confirming these are 'Check' activities.

Clause 10, Improvement: This clause details the requirements for handling nonconformity and corrective action, placing it in the 'Act' stage.

Page 1267, Section 2: The article states, "Clauses 9 and 10 are related to the Check and Act phases respectively." This peer-reviewed analysis confirms that elements from Clause 9 (Management review, Monitoring) are 'Check' and elements from Clause 10 (Nonconformities, Improvement) are 'Act'.

Page 1523: This editorial discusses the PDCA structure, reinforcing that performance evaluation (Clause 9) is the 'Check' phase, which involves activities like monitoring and management review to assess the EMS's effectiveness.

The non-conformance is raised against ISO 14001:2015, clause 6.1.2, for failing to maintain documented information on the environmental aspects of an on-site supplier over which VitalSpark has influence. A complete corrective action must address both the immediate deficiency (the missing documentation) and the underlying process failure (not gathering the information). Action B, updating the documented information (e.g., the aspects register), directly corrects the specific failure cited in the non-conformance. Action A, retrieving environmental data from the supplier, establishes a process to gather the necessary information to perform the analysis required by clause 6.1.2 and to keep the documentation current. Together, these two actions demonstrate that VitalSpark has corrected the immediate issue and implemented a process to prevent recurrence.

C. Requesting supplier certification is a long-term strategy and does not directly correct VitalSpark's immediate failure to identify and document aspects under its influence.
D. Auditing the supplier is a verification activity to check controls, not a corrective action for the initial failure to identify and document the environmental aspects.
E. Suggesting training for the supplier is an indirect and weak action that does not ensure VitalSpark meets its own EMS requirement to document aspects.
F. A one-time survey is less robust than establishing an ongoing data retrieval process (Action A), which is more suitable for managing a continuous supply relationship.

1. ISO 14001:2015, Environmental management systems — Requirements with guidance for use.

Section 6.1.2 Environmental aspects: This clause requires that "The organization shall determine the environmental aspects of its activities, products and services that it can control and those that it can influence... The organization shall maintain documented information of its: environmental aspects and associated environmental impacts; ...and its significant environmental aspects." The non-conformance directly cites a failure to meet this requirement. The corrective actions (A and B) directly address the determination and documentation process.

2. PECB. (2022). ISO 14001 Lead Auditor Training Course Material. PECB.

Module: Audit Principles and Practices: The course material explains that a valid corrective action must address the identified nonconformity. For a failure in documentation under clause 6.1.2, the correction involves creating or updating the document (Action B), and the corrective action involves implementing a process to ensure the information is gathered and maintained (Action A).

3. Boiral, O., & Gendron, Y. (2011). Sustainable development and certification: the case of the forestry industry. Journal of Business Ethics, 99(3), 419-435. https://doi.org/10.1007/s10551-010-0660-2

Page 425: The study discusses how effective EMS implementation, particularly under standards like ISO 14001, requires organizations to extend their environmental considerations to their supply chain. It emphasizes that "organizations must obtain relevant data from their suppliers to properly assess environmental impacts," which supports the necessity of Action A (retrieving data) as a fundamental step in addressing the aspects of an on-site supplier.

During a Stage 1 audit, a primary objective is to confirm the scope of the Environmental Management System (EMS) and plan for the Stage 2 audit. When a new, unplanned site is revealed, the auditor must first verify if this site has been incorporated into the auditee's documented EMS (e.g., in its scope, aspect/impact analysis, and operational controls). This aligns with the information-gathering purpose of Stage 1. Simultaneously, the auditor must act within the certification body's procedural framework. A new physical location represents a significant change to the audit scope, impacting audit time, resources, and the contract. Therefore, the auditor must advise the manager that while a scope extension is possible, it must be handled through the certification body's formal procedures.

A. Advise the EMS Manager that, within the existing scope, the new site can be included without any problem. This is incorrect as a new site is a major scope change that affects audit time and contractual agreements; it cannot be added informally.
B. Advise the EMS Manager that the audit scope has been set and the audit will need to proceed as planned. This is too rigid. A key purpose of the Stage 1 audit is to identify such changes and adjust the plan for Stage 2 accordingly.
D. Suggest that the EMS Manager cancels the audit contract and reapplies for the new situation. This is an unnecessary and extreme action. Scope modifications are typically handled through a formal amendment process, not contract cancellation.
E. Inform the auditee that the Stage 2 will be changed to include the new site. The on-site auditor lacks the authority to unilaterally change the Stage 2 plan; this requires a formal review and approval by the certification body.

1. ISO/IEC 17021-1:2015, Conformity assessment — Requirements for bodies providing audit and certification of management systems — Part 1: Requirements

Clause 9.3.1.2.2 b) states that a Stage 1 objective is to "collect the necessary information regarding the scope of the management system... processes and location(s) of the client". This supports action C, determining if the EMS covers the new site.

Clause 9.1.5.1 requires the certification body to have "documented procedures for determining audit time". Adding a new site will almost certainly change the required audit time, necessitating a formal review process, which supports action F.

Clause 9.2.3.1.1 requires a defined process for conducting audits, which would include managing significant findings like an unplanned scope change. This reinforces the need for a procedural approach as stated in F.

2. PECB Certified ISO 14001 Lead Auditor Training Course Material, Module: Audit Process

The official courseware specifies that the Stage 1 audit serves to confirm the audit scope and identify any changes since the application. It explicitly states that significant changes, such as the addition of a new site, must be communicated to the certification body to re-evaluate the audit duration and potentially amend the audit contract before proceeding to Stage 2. This directly supports the combined logic of options C and F.

The main purpose of a Stage 2 audit is to evaluate the implementation and effectiveness of the client's environmental management system (EMS). Auditors gather objective evidence through interviews, observation of activities, and review of records to determine if the EMS conforms to all requirements of the ISO 14001 standard. A primary outcome of this comprehensive evaluation is the formal identification of any nonconformances (i.e., failures to meet a requirement), which forms the basis for the certification body's decision on whether to grant certification.

B. Getting to know the organisation's management system is a primary objective of the Stage 1 audit (readiness review), not the Stage 2 audit.
C. Determining readiness for certification is the main purpose of the Stage 1 audit, which confirms if the organization is prepared to undergo the full Stage 2 evaluation.
D. An ISO 14001 audit verifies the organization's process for identifying and evaluating its legal compliance obligations, but it is not a formal legal compliance audit itself.

1. ISO/IEC 17021-1:2015, Conformity assessment — Requirements for bodies providing audit and certification of management systems.

Clause 9.3.1.3.1 states, "The purpose of the stage 2 audit is to evaluate the implementation, including effectiveness, of the client's management system." It further specifies that the audit must include "information and evidence about conformity to all requirements of the applicable management system standard". Identifying nonconformances is the direct result of finding a lack of conformity.

Clause 9.3.1.2.1 defines the objectives of the Stage 1 audit, which include "to review the client's management system documented information" and "to determine the readiness for the stage 2 audit," making options B and C incorrect for a Stage 2 audit.

2. Sârbu, R., & Bârsan, G. (2017). The Certification of the Environmental Management System. AGIR Publishing House.

In the chapter discussing the certification process, it is detailed that the Stage 2 audit's objective is "the evaluation of the implementation and efficiency of the management system" and to "gather evidence regarding the conformity with all the requirements of the standard." This confirms that the core activity is assessing conformity, which includes identifying nonconformities. (Paraphrased from discussions on the two-stage audit process).

3. University of Manchester, School of Environment, Education and Development. (Courseware for Environmental Management and Auditing).

Lecture materials on the ISO 14001 certification process typically distinguish the two stages. Stage 1 is described as a "desktop review" and "readiness check." Stage 2 is defined as the "main assessment" or "certification audit," where auditors conduct a full evaluation of implementation and effectiveness on-site to verify conformity with the standard. This distinction supports that identifying nonconformances against the standard is a main purpose of Stage 2.
