Quality Assurance
CAPA, 483 & Warning Letter Remediation
Root-cause investigation, corrective action, and formal FDA response when it counts.
What It Is
Corrective and Preventive Action (CAPA) is the engine of a quality system — how you investigate problems to root cause, correct them, prevent recurrence, and verify effectiveness. When FDA finds problems during an inspection, it issues a Form 483 with observations; unresolved or serious issues can escalate to a Warning Letter. Both demand a structured, evidence-backed response and a credible remediation plan on a tight clock.
When You Need It
You need this service when your CAPA system is generating findings it cannot close, when an audit or inspection produced observations, when you have received a Form 483 or Warning Letter, or when you need to remediate a quality system before it triggers enforcement. Speed and substance both matter — FDA expects a response to a 483 within 15 business days to receive full consideration.
What We Do
We lead disciplined root-cause investigations, write corrective and preventive actions that actually close, and draft the formal FDA response with a credible, dated remediation plan and evidence of correction. We can stand up or repair your whole CAPA system, and we stay through effectiveness verification so the finding does not come back.
We Live It, Not Just Advise It
We run a real CAPA system inside an FDA-registered operation — investigations, corrections, and effectiveness checks that get inspected. We know the difference between a CAPA that closes and one that an investigator reopens, because ours are held to that standard. When we write your response, it reads like it came from an operator who has lived the consequences, because we have.
How AuditIQ Helps
AuditIQ helps triage which quality records and procedures contributed to a finding, accelerating root-cause investigation and helping ensure your remediation covers the systemic issue, not just the symptom.

How quickly do I need to respond to an FDA 483?
To receive full consideration, FDA expects a written response within 15 business days of the inspection close. A strong response acknowledges each observation, states corrections already made, and lays out a dated, credible remediation plan with root-cause analysis. We help you hit that window with substance.
What is the difference between correction and corrective action?
A correction fixes the immediate problem (for example, reworking a nonconforming lot). Corrective action addresses the root cause so the problem does not recur. FDA and auditors look for both — and for effectiveness verification proving the corrective action worked.
Can you help prevent findings in the first place?
Yes — that is what our audit and mock-inspection service is for. The most cost-effective remediation is the 483 you never receive because a mock inspection caught the issue first.
