Process Audit Techniques Flashcards

An auditor reviewing a production process notes that control plans reference inspection criteria not found in any current work instruction. This most likely constitutes a nonconformity against:

Answer: Clause 8.5.1 — Control of production and service provision

Clause 8.5.1 requires documented information defining the results to be achieved; misalignment between control plans and work instructions violates this requirement.

Which question type is most effective for probing whether a process actually achieves its intended outputs?

Answer: 'What happens when this process does not produce the expected result?'

Asking about failure scenarios encourages the auditee to demonstrate real understanding of process controls and response mechanisms, revealing actual effectiveness.

The SIPOC model used in process auditing stands for:

Answer: Supplier, Input, Process, Output, Customer

SIPOC maps Suppliers, Inputs, Process steps, Outputs, and Customers to give auditors a holistic view of a process's boundaries and interactions.

During a process audit, you find that a critical measurement device is out of calibration. What is the auditor's immediate obligation?

Answer: Record the finding and assess its impact on product conformity since the last calibration

ISO 19011 requires auditors to record findings and assess their significance; for an out-of-calibration device, this includes evaluating the validity of previous measurements.

Process performance indicators (PPIs) differ from process effectiveness measures in that PPIs primarily measure:

Answer: The efficiency with which the process converts inputs to outputs

PPIs focus on efficiency metrics such as cycle time, yield, and resource consumption, while effectiveness measures assess whether intended results are achieved.

An auditor wants to verify that the 'Plan-Do-Check-Act' cycle is applied to a logistics process. Which evidence would best confirm the 'Act' phase is functioning?

Answer: Corrective action records showing improvements implemented based on performance data

The 'Act' phase of PDCA involves taking action on significant differences between planned and actual results; corrective action records demonstrate this closing of the loop.

When an auditor identifies a cluster of minor nonconformities in the same process area, the best practice is to:

Answer: Consider whether the cluster indicates a systemic issue warranting a major nonconformity

A cluster of related minor nonconformities may indicate a systemic breakdown; auditors must assess whether the pattern elevates the finding to a major nonconformity.
