Corrective and Preventive Action (CAPA)
The structured improvement workflow triggered by quality failures — root cause investigation, corrective actions taken, preventive measures implemented, effectiveness verification, and closure approval.
Why This Object Matters for AI
AI-assisted CAPA requires a machine-readable history of past corrective actions and their outcomes; without it, the system cannot recommend effective fixes or predict closure timelines.

CMC Dimension Scenarios
What each CMC level looks like specifically for Corrective and Preventive Action (CAPA). Baseline level is highlighted.
Corrective actions happen informally. When a quality problem recurs, the supervisor says 'we need to fix that' and someone adjusts the process. There's no record of what was done or why. Six months later, the same problem returns and nobody remembers the previous fix.
AI cannot recommend corrective actions because no history of what worked or failed exists.
Require any written record when corrective action is taken — even a notebook entry describing the problem and what was done.
CAPAs are documented in a shared folder or email thread. When a significant quality issue arises, the quality manager writes up what happened and what was done. The format varies — some are detailed, others are 'fixed the machine, issue resolved.' Finding past CAPAs means searching through folders by memory.
AI can count CAPAs and search by keyword, but cannot analyze effectiveness patterns or recommend actions because documentation is inconsistent and unstructured.
Standardize CAPA documentation with required fields: problem statement, root cause, corrective action, preventive action, verification method, and closure date.
A standard CAPA form exists with defined sections: problem description, root cause analysis method (5-Why, fishbone), immediate containment, corrective action, preventive action, and verification plan. All CAPAs use the same template. But CAPAs aren't linked to triggering NCRs or outcome data.
AI can generate CAPA status reports and track closure rates. Cannot correlate CAPAs with triggering events or measure actual effectiveness.
Link CAPAs to triggering NCRs, inspection failures, and customer complaints as structured references. Add post-verification outcome tracking.
CAPAs are structured records with entity links. Each CAPA references the triggering NCR(s), affected products, process steps involved, and verification results. The quality team can query 'show me all CAPAs triggered by supplier defects in 2025 and their recurrence rates' and get data.
AI can analyze CAPA effectiveness by correlating with outcome data. Pattern detection across root causes and successful remedies is possible.
Add formal ontological relationships — CAPAs as nodes in a graph linked to root causes, corrective action types, verification outcomes, and similar historical cases.
CAPAs exist in a quality knowledge graph with typed causal relationships. Each CAPA links to root cause categories, corrective action patterns that worked, and long-term effectiveness metrics. The graph captures which actions prevented recurrence vs. which failed. An AI can ask 'what corrective actions have been most effective for tool wear root causes?'
AI can recommend corrective actions based on historical effectiveness. Predictive CAPA prioritization based on impact likelihood is possible.
Implement real-time graph updates — CAPA outcomes and recurrence data feed back into the graph automatically as new evidence arrives.
The CAPA knowledge graph learns continuously. When a new NCR arrives, the system identifies similar historical cases and recommends proven corrective actions. When a CAPA is verified, effectiveness data strengthens or weakens the associated action patterns. The organization's quality improvement knowledge compounds over time.
Fully autonomous CAPA recommendation. AI can propose root causes, suggest corrective actions, predict effectiveness, and learn from outcomes without human pattern-matching.

Capabilities That Depend on Corrective and Preventive Action (CAPA)
Other Objects in Quality Management
Related business objects in the same function area.
Product Specification
EntityThe formal definition of what constitutes an acceptable product — tolerances, dimensions, material properties, GD&T, and acceptance criteria that every quality decision references.
Inspection Record
EntityThe documented result of a quality inspection event — measurements taken, pass/fail outcomes, inspector identity, and traceability to the specific lot, part, or process step evaluated.
Non-Conformance Report
EntityThe formal record of a product or process deviation from specification — what went wrong, when, where, severity classification, and disposition decision (scrap, rework, use-as-is, return).
Supplier Quality Profile
EntityThe aggregated quality performance record for each supplier — incoming inspection results, audit findings, certification status, delivery performance, and risk scores maintained by the supplier quality team.
Process Control Record
EntityThe SPC data, control limits, process parameters, and control charts that define and monitor the statistical behavior of a manufacturing process — owned by process engineers and reviewed per shift or per run.
Regulatory Requirement
RuleThe external compliance obligations from regulatory bodies (FDA, ISO, industry standards) and customer contracts that products and processes must satisfy — maintained as a structured database of applicable requirements.
Customer Quality Feedback
EntityThe structured record of customer-reported quality issues — complaints, warranty claims, return reasons, field failure reports, and satisfaction survey data linked back to internal production lots and processes.
Quality Cost Record
EntityThe tracked cost of quality — scrap costs, rework costs, warranty expenses, inspection costs, and prevention investments categorized by product, process, and time period for quality economics decision-making.
