You work as an external quality consultant for an organisation, ‘A’, which provides packaged food to the public. You are asked to lead a team (you as the leader and two other auditors) to audit a supplier, ‘B’, to ISO 9001 which provides packaging materials to your organisation. It is 4 pm and the audit is close to an end; you are having an internal meeting with the team to decide what will be presented to the auditee during the Closing meeting. The Closing meeting was scheduled at 5 pm.
You, as Audit Team Leader, audited top management. You explain to the audit team that you identified two nonconformities:
a. There is no documented information on Top Management Reviews, as required in clause 9.3 of ISO 9001:2015.
b. There is no evidence of Top Management Commitment as required in clause 5.1 of ISO 9001:2015. (e.g., not ensuring the availability of resources to operate the QMS, not ensuring the establishment of objectives, no promotion of improvement, no promotion of the process approach).
All agreed to present these two nonconformities. They went to meet the Top Management of ‘B’ and noticed that the General Manager and three other managers (Production, Human Resources, and Sales) were present in the meeting room.
Considering the seriousness of the two nonconformities to Top Management, as audit team leader, from the following select the best option:
- A . Present the nonconformities to the whole group and inform that you will recommend your company to remove them from the approved suppliers list.
- B . Present the nonconformities to the managers, inform them that the report will be sent within 10 days, close the meeting and leave the site.
- C . Ask the General Manager to have a private conversation in which you present the nonconformities only to him because of their sensitive nature.
- D . Present the nonconformities to the whole group and analyse with them how to overcome this situation.

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.

You are auditing an organisation that has been certificated to ISO 9001 for ten years. The organisation is a privately-owned, multi-site car tyre fitting organisation. You are auditing one of the sites. You are auditing the car tyre fitting service. You are interviewing the Site Manager (SM).
You: "Would you explain the car tyre fitting service?"
SM: "Of course. Customers typically call us by phone with their requirements. We ask them what they want. We check whether we have the tyres
they need in stock. If we don’t have the tyres in stock, we contact our supplier to confirm when they would be able to supply the tyres. We then determine the cost. We then check what availability we have in our busy schedule to fit the new tyres. We then inform the customer with details of cost and when we can fit the tyres. If the customer is happy to proceed with the booking, we update our Work Schedule. The same process applies for customers who walk into our office and for online requests."
You: "What information do you retain should there be a defect reported by a manufacturer of tyres that you have fitted?"
SM: "We maintain records of customer names, addresses and contact phone numbers. We maintain a record of the type of tyre fitted and the tyre manufacturers batch information. We also maintain a record of the registration numbers of the vehicles we have fitted tyres to. All records are in our Work Schedule."
Which two of the following options you would take to enable you to gather further audit evidence to validate what the Site Manager has told you?
- A . Interview a customer to determine how satisfied they are with the service.
- B . Interview a tyre fitter to determine how long they have worked for the organisation.
- C . Interview a tyre fitter to determine the type and batch of each tyre fitted to a car.
- D . Review the training record of the site manager.
- E . Review the Work Schedule dated three years ago and verify what information has been recorded.
- F . Review the Work Schedule for the past three weeks and verify what information has been recorded.

You, as auditor, are in dialogue with the quality lead and managing director of a small business that supplies specialist laboratory equipment and furniture.
You: "I’d like to look at how you manage change in the organisation.
What changes have you made as a business, say, over the last 12 months?"
Auditee: "We have made some strategic changes, the main one being that we no longer manufacture our
own products in house."
You: "That sounds like quite a significant change.
What has been the impact of that?"
Auditee: "We now mainly sell other manufacturers’ products, under their brand names, and have outsourced manufacture of our own brand products to one of our suppliers. Unfortunately, we had to make six members of our staff redundant. This represents about 20% of our workforce, so this has been quite a challenging time."
You: "I’m sure.
What were the reasons for making the change?"
Auditee: "Our manufacturing section was a small operation, and we struggled to cope with fluctuations in demand. During busy periods, we found it hard to meet lead times, and in quiet periods we had staff with little to do. This was having an impact on customer satisfaction and meant we had to charge premium prices that made our product uncompetitive."
You: "How did you go about the change?"
In relation to the auditor’s question about how the change was managed, the auditee mentions the steps listed below. Match the ISO 9001 clauses to the steps.
To complete the table, click on the blank section you want to complete so it is highlighted in red and then click on the ISO 9001 clauses listed below. Alternatively, drag and drop each clause to show which step the requirement applies to.
