You are carrying out an audit at an organisation seeking certification to ISO 9001 for the first time. The organisation offers health and safety training to customers. Training courses are offered either as open courses, delivered at a public venue, or online, or as courses that are tailored to meet specific requirements. The business operates from a single office and those who deliver the training are either full-time employees or subcontractors.
You have just completed the opening meeting. You are interviewing the Managing Director (MD).
You: “Good morning. I would like to gain an understanding of your business and its strategic direction.”
MD: “Of course. We are facing challenging times. The market is extremely competitive, and customers typically look for the least expensive option when arranging health and safety training. Our annual sales revenue has struggled to grow over the past two years. Most of our employed trainers are planning to retire over the next 12 months, and we are looking for more subcontract trainers. Achieving ISO 9001 certification will, I hope, give us the capability to improve our operational performance. Also, many of our competitors do not have any form of management system certification, so I hope it will give us that competitive edge needed to secure orders. We intend to promote our ISO 9001 certification on our website and across all other customer-facing media.”
Which three of the following audit trails would you take to explore the extent to which external and internal issues have been determined and used to enable the business to achieve the intended result(s) of its quality management system?

The company has around 14,000 employees working in different sectors which help with the design, painting, assembling, and test drives of the final product. The company is widely known for its qualitative products and affordable prices. In order to retain their reputation, POLKA implemented a quality management system (QMS) based on ISO 9001.
Before applying for certification, the company decided to conduct an internal audit to check whether there are any nonconformities in their QMS and if the requirements of ISO 9001 are being fulfilled. The top management appointed Sean, the internal auditor, as the team leader of the internal audit team. Sean required from the top management to have unrestricted access to the employees and executives of POLKA and to the documented information. Furthermore, Sean required to establish a team with a large number of auditors, considering the size and the complexity of the organization. The top management of POLKA agreed with Sean ' s requirements.
The top management, in cooperation with Sean, assigned 10 more employees to the audit team. Following that. Sean planned the audit activities and assigned the roles and responsibilities to each auditor.

Scenario 5: Mechanical-Electro (ME) Audit Stages
Mechanical-Electro, better known as ME, is an American company that provides mechanical and electrical services in China. Their services range from air-conditioning systems, ventilation systems, plumbing, to installation of electrical equipment in automobile plants, electronic manufacturing facilities, and food processing plants.
Due to the fierce competition from local Chinese companies and failing to meet customer requirements, ME ' s revenue dropped significantly. In addition, customers ' trust and confidence in the company decreased, and the reputation of the company was damaged.
In light of these developments, the top management of ME decided to implement a quality management system (QMS) based on ISO 9001. After having an effective QMS in place for over a year, they applied for a certification audit.
A team of four auditors was appointed for the audit, including Li Na as the audit team leader. Initially, the audit team conducted a general review of ME ' s documents, including the quality policy, operational procedures, inventory lists, QMS scope, process documentation, training records, and previous audit reports.
Li Na stated that this would allow the team to maintain a systematic and structured approach to gathering documents for all audit stages. While reviewing the documented information, the team observed some minor issues but did not identify any major nonconformities. Therefore, Li Na claimed that it was not necessary to prepare a report or conduct a meeting with ME ' s representatives at that stage of the audit. She stated that all areas of concern would be discussed in the next phase of the audit.
Following the on-site activities and the opening meeting with ME ' s top management, the audit team structured an audit test plan to verify whether ME’s QMS conformed to Clause 8.2.1 (Customer Communication) of ISO 9001.
To do so, they gathered information through group interviews and sampling. Li Na conducted interviews with departmental managers in the first group and then with top management. In addition, she chose a sampling method that sufficiently represented customer complaints from both areas of ME ' s operations.
The team members were responsible for the sampling procedure. They selected a sample size of 4 out of 45 customer complaints received weekly for electrical services and 2 out of 10 complaints for mechanical services.
Afterward, the audit team evaluated the evidence against the audit criteria and generated the audit findings.
According to scenario 5, Li Na conducted group interviews with departmental managers and top management by herself. Is this in accordance with audit best practices?
Among others, what does Clause 4.4 (Quality Management System and Its Processes) of ISO 9001 require from organizations?
XYZ Corporation is an organisation that employs 100 people. As audit team leader, you are conducting a
certification audit at Stage 1. When reviewing the quality management system (QMS) documentation, you
find that quality objectives have been set for every employee in the organisation except top management.
The Quality Manager complains that this has created a lot of resistance to the QMS, and the Chief Executive
is asking questions about how much it will cost. He asks for your opinion on whether this is the correct
method of setting objectives.
Three months after Stage 1, you return to XYZ Corporation to conduct a Stage 2 certification audit as Audit
Team Leader with one other auditor. You find that the Quality Manager has cancelled the previous quality
objectives for all employees and replaced them with a single objective for himself. This states that " The
Quality Manager will drive multiple improvements in the QMS in the next year " . The Quality Manager indicates
that this gives him the authority to issue instructions to department managers when quality improvement is
needed. He says that this approach has the full backing of senior management. He shows you the latest
Quality Improvement Request that was included in the last management review.
After further auditing, the issues below were found. Select three statements that apply to the term ' audit trail '
According to the guidance provided in ISO 19011, a second-party opening meeting should cover many elements.
From the following options, select the four items that should not be included in the opening meeting.
Select the term which best describes the quality management system process of modifying a non-conforming product to bring it within acceptance criteria.
You are conducting a Stage 1 audit at an organisation that services refrigeration equipment for a large customer base. The scope of certification is “Provision of refrigeration equipment maintenance and repair services”. You are interviewing the Managing Director to learn more about the organisation and to explore how the requirements for policy, objectives, and risks and opportunities in ISO 9001 are addressed.
The Managing Director explains that they only use sub-contract refrigeration engineers and do not have any full-time refrigeration engineers, which helps to optimise overhead costs. The full-time staff employed are essentially a small team of office staff who process customer enquiries, schedule jobs and process invoices.
The Managing Director adds that the ISO 9001 requirements for competence of personnel extends to both sub-contract and full-time staff. He also states that the full-time staff are aware of the Quality Policy, objectives and plans to address risk and opportunities.
You ask if the sub-contract engineers have been informed of the Quality Policy, objectives and plans to address risks and opportunities, to which the Managing Director replies that this is not applicable as they only use sub-contractors who operate ISO 9001 certificated quality management systems. The documented information provided to the auditor confirms this.
Which clause in ISO 9001 is most likely not to have been fulfilled in this instance?
