This is a ready-to-use controlled register, the single source of truth for the response, the periodic update letters, and the follow-up inspection. When FDA returns, they pull the response and verify each commitment one at a time; a clean, evidenced register is what shows an organization in control. Replace each <<FILL: ...>> placeholder with your own specifics. A filled specimen follows.
Document control header
| Field | Entry |
|---|---|
| Register title | 483 / Warning Letter Commitment and Effectiveness Register |
| Register number | <<FILL: LOG-ID>> |
| Linked response | <<FILL: 483 or Warning Letter reference and response date>> |
| Owner | <<FILL: role, e.g. Head of Quality>> |
| Review cadence | <<FILL: weekly during active remediation>> |
| Retention | Life of the matter plus the records retention schedule, not less than <<FILL: retention period>> |
Purpose
To hold every commitment made to FDA in one place, mapped to its owner, its date, its evidence, and its effectiveness check, so that nothing promised is lost and no gap opens between what was promised and what can be shown. The register is the spine of the remediation: it drives the standing remediation meeting, it feeds the periodic update letters, and it is what an investigator is handed at the follow-up inspection.
Field definitions
| Field | Format | Required | Who enters | When |
|---|---|---|---|---|
| Commitment ID | Stable ID | Yes | Quality | When the response is finalized |
| Observation / finding | Observation number | Yes | Quality | At entry |
| Commitment text | Text, quoted from the response | Yes | Quality | At entry |
| Type | Immediate correction / systemic action / effectiveness check | Yes | Quality | At entry |
| Owner | One named person, not a department | Yes | Quality | At entry |
| Committed date | Date told to FDA | Yes | Quality | At entry |
| Status | Not started / in progress / complete / at risk | Yes | Owner | At each review |
| Evidence reference | Document, record, or system entry that proves it | Yes at completion | Owner | On completion |
| Effectiveness check date and result | Date verified and outcome | Yes for systemic actions | Quality | At the check |
| Disclosure note | Any FDA notification of a change or slip | Yes when applicable | Quality | On any change |
Instructions for use
- Create one row per discrete commitment the moment the response is finalized; quote the commitment text exactly so there is no drift between what was promised and what is tracked.
- Assign one accountable person per row, never a department, so accountability is unambiguous.
- Review the register at a standing meeting, weekly during active remediation. Set any row that will miss its date to “at risk” before the date, not after.
- If a committed date will slip, notify FDA in writing before the deadline, record the notification in the disclosure note, and enter the revised date. Silent slippage discovered at the follow-up inspection is the worst outcome; disclosed slippage managed in the open reads as a functioning system.
- A commitment is not complete until its evidence reference points to a real record, and a systemic action is not closed until its effectiveness check has a date and a result.
- Use the register to build periodic update letters (often every 30 or 60 days) that report progress against each commitment.
Acceptance criteria
- Every commitment in the response appears exactly once, with text quoted from the response.
- Every row has one named owner and a committed date.
- No completed row lacks an evidence reference.
- Every systemic action has an effectiveness check with a date and a result before it is closed.
- Any date change was disclosed to FDA before the original date and is recorded.

Row C-04 is the one to manage: it is “at risk” ahead of its week-6 date. The right move is a written note to FDA before week 6 with a revised date, recorded in the disclosure note, not a silent slip discovered later. Row C-03 shows partial progress (11 of 17) with the effectiveness check already scheduled, which is exactly what an investigator wants to see: a plan, live progress, and a defined proof point.
Common inspection findings this register prevents
- A gap between what was promised and what can be shown at the follow-up inspection.
- Commitments owned by a department, so no one was actually accountable when a date slipped.
- A completion claimed with no evidence, or a systemic action closed with no effectiveness check.
- A missed commitment discovered by the investigator because the slip was never disclosed.
How to adapt this register
- Set your register number and the linked response reference in the header.
- If your CAPA system can hold these fields, run the register inside it and export for the update letters, so the commitment tracking and the CAPA records are one system.
- Add a column for the periodic update letter in which each commitment was last reported, so the letters and the register never diverge.
- Keep the register the single source of truth: the response, the update letters, and the follow-up inspection all read from it.
- Confirm every regulation in the references against the current published version before you rely on it.
