You are conducting an ISO 9001:2015 audit of the Human Resource department. You ask the Human Resource Manager how the organisation ensures that personnel performing work are suitably competent. He replies that all personnel are qualified and trained. You then sample the records of five people working in the customer service department. On each person’s record is a list of the academic qualifications they hold, as well as a list of the in- house training courses they have attended. You note that all five people have attended the same courses: an induction course, a behavioural safety course, a managing people course, and a basic IT course

1-Explain what a concern here may be

2-Based on the concern you identified in Part A above, briefly describe four audit trails you would follow to determine conformity or nonconformity to the requirements of ISO 9001:2015. For each, identify the applicable clause(s) of ISO 9001:2015 and any audit evidence you would gather.
