Inspection Prep Checklist — CAPA Effectiveness

21 CFR 211.192 CAPA Effectiveness · Pre-Inspection Review ComplianceWorxs · 2026

CAPA effectiveness is the most frequently cited authorization gap in quality system inspections. The failure mode is consistent: the CAPA was implemented, the root cause was addressed, and the closure record contains a signature — but no document captures who authorized the effectiveness determination, what evidence they reviewed, or what standard they applied. This checklist identifies that gap before the investigator does.

01 For every CAPA closed in the review period

Investigator's question

"Who determined this CAPA was effective — and what is the record of that determination?"

A document exists that captures the effectiveness determination as a formal decision — not just a closure signature on the CAPA record
The individual who made the effectiveness determination is identified by name and title — with the date and time of their determination
The effectiveness determination was made by or reviewed and authorized by the Quality Unit — not solely by the department that implemented the corrective action
The effectiveness determination was made at the required timepoint(s) specified in the CAPA plan — not at an earlier or later point without documented authorization of the timing change

02 For the effectiveness evidence itself

Investigator's question

"What specific data did the reviewer examine to conclude this corrective action was effective — and where is that documented?"

The specific evidence reviewed is itemized — not described generically as "reviewed implementation records" but with actual documents, dates, and data referenced
The effectiveness threshold is stated — what metric, observation period, or outcome standard was used to conclude the action was effective
The pre-CAPA baseline is referenced — the effectiveness determination describes the condition before the corrective action and compares it to the condition after
The observation period is documented — how long post-implementation was monitored, and why that period was sufficient to conclude effectiveness

03 For CAPAs with recurrence risk

Investigator's question

"If this root cause recurs, will the prior effectiveness determination be defensible — or will it become evidence of a systemic failure to control the cause?"

The effectiveness authorization record is complete enough to reconstruct the decision if the same root cause reappears in a future inspection
Any prior CAPAs addressing the same or similar root cause are referenced — and their effectiveness determinations are evaluated in the current record
The record documents why the corrective action was concluded to address the root cause permanently — not just the immediate symptom

The gap that compounds

CAPA closed. Root cause recurred. Prior effectiveness record is empty.

When a root cause recurs, the investigator reviews the prior CAPA closure. If the effectiveness determination record is a signature without substance, the recurrence is not just a new finding — it retroactively invalidates the prior closure. A CAPA effectiveness authorization record must be complete enough to defend the determination if the root cause appears again twelve months later.

The CAPA Effectiveness Authorization case file produces a structured effectiveness determination record at the time of closure — capturing all five elements the investigator will look for.
