100 Difficult Inspector Questions P2

How can you prove that your data are reliable?

We maintain data integrity through ALCOA principles, audit trail reviews, access controls, and periodic assessments.

What evidence demonstrates data integrity compliance?

Audit trails, access logs, training records, procedures, and system validation documents.

How do you know data have not been manipulated?

Audit trail reviews and access controls provide evidence of data integrity.

Who reviews audit trails?

Authorized personnel review audit trails according to approved procedures.

How often are audit trails reviewed?

The frequency is defined by risk assessment and approved procedures.

What would you do if an audit trail review identified an issue?

We would investigate the event, assess impact, and implement CAPA if necessary.

Can users delete GMP data?

No. User permissions are controlled and restricted according to roles.

How do you control administrator privileges?

Administrator access is limited, justified, documented, and periodically reviewed.

How do you ensure electronic records are trustworthy?

Through validated systems, audit trails, security controls, and backup procedures.

How do you verify backup effectiveness?

Periodic restoration testing demonstrates that backup data can be recovered.

What would happen if your system failed today?

Data could be restored using approved disaster recovery procedures.

How do you know your computerized system is validated?

Validation documentation demonstrates that the system performs as intended.

Can you show evidence that the system remains validated?

We maintain change control, periodic review, and ongoing monitoring records.

Why was this system change not revalidated?

Risk assessment concluded that revalidation was not required, and supporting documentation is available.

How do you justify that decision?

The decision was based on documented risk assessment and system impact evaluation.

What evidence supports your validation status?

Approved protocols, reports, testing records, and periodic review documentation.

How do you know your validation acceptance criteria are appropriate?

They are scientifically justified and approved before execution.

What if validation results are borderline?

The results would be evaluated according to predefined criteria and quality risk assessment.

How do you know your process remains validated?

Continued process verification confirms ongoing process performance.

What trending data support that conclusion?

Process parameters, deviations, complaints, yields, and quality metrics.

How do you justify your cleaning validation limits?

The limits are scientifically justified based on toxicity, dosage, and risk assessment.

Why was this product selected as the worst case?

It represents the highest cleaning challenge based on predefined criteria.

How do you know your cleaning procedure is effective?

Cleaning validation results consistently meet acceptance criteria.

Can visual inspection alone demonstrate cleanliness?

No. Visual inspection is important but must be supported by validation data when required.

What evidence demonstrates cleaning effectiveness?

Cleaning validation reports, swab results, rinse results, and routine verification records.

How do you know cross-contamination is controlled?

We use validated cleaning procedures, segregation, and environmental controls.

What would happen if cleaning failed?

The equipment would not be released for production until the issue is resolved.

How do you assess contamination risk?

Through quality risk assessment and process evaluation.

How do you know environmental monitoring is effective?

Trend data demonstrate stable environmental conditions within limits.

What evidence supports your environmental control program?

Monitoring records, investigations, trend reports, and CAPA records.

How do you justify your sampling plan?

The plan is based on scientific rationale, risk assessment, and regulatory expectations.

How do you know the samples are representative?

Sampling locations and quantities are scientifically justified.

Why did you choose this testing frequency?

The frequency is based on risk, historical performance, and regulatory requirements.

Can you prove this process is capable?

Process performance data consistently meet predefined acceptance criteria.

How do you know your specifications are appropriate?

Specifications are supported by development, validation, and regulatory approval data.

What evidence demonstrates batch consistency?

Validation data, trend analysis, and product quality reviews.

How do you know operators consistently follow procedures?

Training records, supervision, audits, and performance monitoring provide evidence.

What if an operator intentionally bypasses a procedure?

The issue would be investigated and managed according to quality procedures.

How do you detect undocumented activities?

Through audits, supervision, data review, and quality oversight.

Why should I trust your documentation?

The records are contemporaneous, reviewed, controlled, and supported by objective evidence.

Can you prove this entry was made at the correct time?

The timestamp, record review, and supporting evidence demonstrate contemporaneous recording.

How do you prevent backdating of records?

Procedural controls, supervision, and data integrity measures help prevent backdating.

What would you do if you discovered a data integrity breach?

We would immediately investigate, assess impact, escalate appropriately, and implement CAPA.

How do you determine whether a quality issue is systemic?

Trend analysis and investigation findings are used to assess systemic impact.

How do you ensure lessons learned are implemented?

Lessons learned are incorporated into CAPAs, procedures, and training programs.

How do you demonstrate a culture of quality?

Employees report issues openly, investigations are evidence-based, and management supports quality decisions.

What is the strongest evidence of GMP compliance?

Consistent documentation, controlled processes, reliable data, and effective quality systems.

How do you prepare for regulatory inspections?

We maintain inspection readiness through compliance, training, self-inspections, and continual improvement.

What would concern you most if you were the inspector?

Any situation where product quality, patient safety, or data integrity could be compromised.

What is your approach when facing a difficult inspection question?

I provide factual, evidence-based answers supported by approved records and documented data.
