BioBoston Consulting – One Stop Solution for Life Sciences

Before You Begin — Are These Internal & Supplier Audit Challenges Impacting Your Operations?

• Are you unsure whether your suppliers consistently meet GMP, GDP, or ISO compliance requirements?
• Do you lack a structured internal audit program to identify gaps before regulators do?
• Are recurring deviations, documentation issues, or uncontrolled processes slowing down your approvals?
• Is your audit team understaffed or lacking expertise in FDA, EMA, or global regulatory expectations?
• Do you struggle to manage supplier qualification, requalification, and ongoing performance monitoring?

If these questions feel familiar, you may have hidden risks within your operations or supply chain—making Internal and Supplier Audits essential to protect compliance, product quality, and patient safety.

What Are Internal & Supplier Audits?

Internal Audits

Internal audits are systematic, independent evaluations of your own processes, systems, documentation, and compliance practices. They help identify gaps, verify adherence to GxP standards, and ensure your Quality Management System (QMS) is functioning effectively.

Internal audits typically cover:

• Document control
• Training records
• Change control
• Deviations and CAPA
• Equipment and facility controls
• Data integrity and Part 11 compliance
• Manufacturing and laboratory practices
• Supplier oversight
• Risk management

Supplier Audits

Supplier audits (also known as vendor audits or third-party audits) assess the compliance, capability, and reliability of your external partners who provide raw materials, packaging, equipment, testing services, logistics, or contract manufacturing support.

Supplier audits ensure:

• Materials meet quality standards
• Processes comply with GMP/GDP/ISO requirements
• Data integrity and documentation are robust
• Facilities and controls are adequate
• Risks in the supply chain are minimized

Together, internal and supplier audits form a complete quality oversight framework, protecting your operations from costly compliance failures.

Why Are Internal & Supplier Audits Important?

1. Prevent FDA 483s & Regulatory Findings

Audits help identify and correct gaps before regulators discover them. Strong audit programs significantly reduce inspection risks.

2. Strengthen QMS & Operational Excellence

Regular audits keep your systems aligned with regulatory expectations and ensure continuous improvement.

3. Ensure Supplier Reliability & Product Quality

Poor supplier performance can lead to contamination, product failures, or batch rejections. Supplier audits protect your supply chain.

4. Maintain Data Integrity Across Operations

Audits highlight issues in electronic systems, batch records, lab documentation, and audit trails—areas frequently examined during FDA inspections.

5. Reduce Costly Deviations & Rework

Identifying issues early helps avoid expensive remediation, product delays, or compliance escalations.

6. Build Better Audit Readiness

A strong audit program prepares your teams for regulatory audits with confidence, clarity, and documented controls.
