Questions for senior management
How are policy and objectives linked to strategy? Which risks could prevent intended results? What significant changes have occurred since the last management review?
Process-approach questions
What are the process inputs, outputs, owners and indicators? How are interfaces with other processes controlled? What happens when an output misses its acceptance criterion?
Customer-related questions
How are requirements identified and reviewed? How is satisfaction measured? Which recent complaints or trends have led to changes?
Supplier questions
How are suppliers selected and re-evaluated? How is the type and extent of control determined? What action is taken when performance is poor?
Risk and change questions
How are risks evaluated? How are changes approved? Which impacts, resources, competencies and documents are reviewed before implementation?
Nonconformity questions
How is the issue contained? How is the cause determined? How do you verify that the action prevents recurrence?
Improvement questions
Which recent improvements can be demonstrated with data? Which opportunities were prioritized and why? How was the resulting benefit verified?
Practical tip: Prepare answers that agree with real records. A convincing explanation without objective evidence is rarely sufficient.
