Distinguish containment, correction and prevention as three separate stages of a CAPA response.
Quality & Productivity

About the programme
Course Overview
Most organisations have a corrective and preventive action form; far fewer can prove that closed actions actually stopped the problem they were opened against. This course treats CAPA as a system with inputs, investigation methods and closure criteria, not a form to fill in after an audit finding. Sessions compare structured root cause methods, including the eight disciplines or 8D report, A3 problem solving and fault tree analysis, and show when each is proportionate to the size of the problem. Participants learn to separate containment, which protects the customer immediately, from correction, which removes the root cause of an existing problem, and from prevention, which stops a similar problem occurring somewhere it has not yet appeared. A substantial part of the course is spent on the step organisations skip most often: verifying effectiveness through a defined monitoring period, a genuine before-and-after comparison, or a shift visible on a control chart, rather than closing an action once the immediate symptom disappears. The course finishes with CAPA system governance, covering cycle time, overdue action metrics, recurrence tracking and how CAPA data should feed management review instead of sitting in a spreadsheet nobody revisits.
Expected Learning Outcomes
Select between 8D, A3 problem solving and fault tree analysis based on the scale of the problem.
Facilitate a root cause investigation that identifies a verifiable cause rather than a plausible guess.
Design an effectiveness verification check using a defined monitoring period or a control chart comparison.
Distinguish a corrective action that removed a root cause from one that only masked a symptom.
Track CAPA system metrics, including cycle time, overdue actions and recurrence rate.
Feed CAPA trends and overdue items into a management review agenda for genuine senior visibility.
Who Should Attend
Quality engineers who own the corrective and preventive action process within a management system.
Cross-functional problem-solving team leaders running 8D or A3 investigations.
Internal auditors assessing whether a CAPA system produces durable fixes rather than paperwork.
Quality managers reporting CAPA performance and recurrence trends to senior leadership.
Continuous improvement specialists supporting root cause investigations across multiple sites.
Engineers who repeatedly see the same failure reappear after previous corrective actions were closed.

01The Anatomy of a Corrective and Preventive Action System
2 sessions · 8 points
Session 1Containment, Correction and Prevention
- Separate containment, which protects the customer now, from correction, which removes the underlying cause.
- Define preventive action as addressing a potential problem that has not yet occurred anywhere in the system.
- Trigger a CAPA appropriately from sources such as audit findings, complaints, scrap data or near misses.
- Set a proportionate response so a minor issue does not receive the same investigation depth as a major failure.
Session 2Structuring a CAPA System That People Actually Use
- Design a CAPA intake process that captures enough detail without discouraging staff from raising issues.
- Assign clear ownership for each CAPA so investigation and closure do not stall for lack of a named owner.
- Set realistic target closure dates that reflect investigation complexity rather than an arbitrary standard interval.
- Choose how an electronic quality management system or simple register will track CAPA status and history.
02Root Cause Investigation Methods
2 sessions · 8 points
Session 1The Eight Disciplines and A3 Problem Solving
- Work through the eight disciplines from team formation and problem description to root cause and closure.
- Use an A3 problem-solving format to keep an investigation visible on a single page throughout its life.
- Separate a verified root cause from a contributing factor that made the problem worse but did not cause it.
- Test a proposed root cause against the evidence before committing resources to a corrective action.
Session 2Fault Tree Analysis and Choosing the Right Method
- Build a fault tree that traces a top-level failure down through intermediate and basic causes logically.
- Apply Boolean logic gates within a fault tree to distinguish causes that combine from causes that act alone.
- Match investigation method to problem scale, reserving fault tree analysis for complex or safety-related failures.
- Combine quantitative failure data with qualitative interviews when a root cause is not immediately obvious.
03Verifying That a Fix Actually Works
2 sessions · 8 points
Session 1Designing an Effectiveness Verification Check
- Define what evidence would prove a corrective action worked before the action is even implemented.
- Set a monitoring period long enough to capture the defect's normal frequency of occurrence.
- Compare defect or complaint data from before and after implementation using a consistent measurement method.
- Use a control chart to check for a genuine shift in performance rather than relying on a single good week.
Session 2Common Ways Effectiveness Verification Fails
- Recognise premature closure, where an action is marked complete before the monitoring period has finished.
- Identify a corrective action that removed a symptom while leaving the underlying root cause untouched.
- Reopen a CAPA when a monitored defect reappears instead of raising an unrelated new action for it.
- Distinguish a temporary improvement caused by attention to a problem from a durable process change.
04Governing the CAPA System
2 sessions · 8 points
Session 1Metrics That Reveal Whether CAPA Is Working
- Track CAPA cycle time from opening to verified closure across different problem categories.
- Monitor overdue and aging CAPA counts to catch a system that is quietly falling behind.
- Calculate a recurrence rate that shows how often closed actions fail to prevent the same problem returning.
- Segment CAPA metrics by source, such as audit, complaint or internal defect, to spot systemic weaknesses.
Session 2Connecting CAPA to Audits and Management Review
- Link CAPA arising from internal or external audit findings back to the specific clause or requirement raised.
- Present CAPA trends and overdue items at management review in terms leadership will act on.
- Escalate a CAPA that has failed verification more than once to a higher level of investigation and sponsorship.
- Audit the CAPA system itself periodically to confirm root causes, not just symptoms, are being closed out.
