Investigate root causes and manage CAPAs (Corrective and Preventive Actions) for compliance deviations. Covers investigation method selection (5-Why, fishbone, fault tree), structured root cause analysis, corrective vs preventive action design, effectiveness verification, and trend analysis. Use when an audit finding requires a CAPA, when a deviation or incident occurs in a validated system, when a regulatory observation needs a formal response, when a data integrity anomaly requires…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Investigate CAPA Root Cause

Conduct a structured root cause investigation and develop effective corrective and preventive actions for compliance deviations.

## When to Use

- An audit finding requires a CAPA
- A deviation or incident occurred in a validated system
- A regulatory inspection observation needs a formal response
- A data integrity anomaly requires investigation
- Recurring issues suggest a systemic root cause

## Inputs

- **Required**: Description of the deviation, finding, or incident
- **Required**: Severity classification (critical, major, minor)
- **Required**: Evidence collected during the audit or investigation
- **Optional**: Previous related CAPAs or investigations
- **Optional**: Relevant SOPs, validation documents, and system logs
- **Optional**: Interview notes from involved personnel

## Procedure

### Step 1: Initiate the Investigation

```markdown
# Root Cause Investigation
## Document ID: RCA-[CAPA-ID]
## CAPA Reference: CAPA-[YYYY]-[NNN]

### 1. Trigger
| Field | Value |
|-------|-------|
| Source | [Audit finding / Deviation / Inspection observation / Monitoring alert] |

How to install

The exact contents, by fingerprint
mdr add pjt222/agent-almanac/investigate-capa-root-cause@sha256:0b1391f595b31cd8

The line at the top of this page pins the label v1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
