Corrective and preventive actions: CAPA and examples
Corrective and preventive actions: CAPA and examples
The corrective and preventive actions are the heart of any quality management system in the food industry. However, many quality teams manage them reactively, incompletely, or without proper follow-up, causing the same problems to repeat over and over. In this article we explain how to design a system of corrective and preventive actions that actually works, from opening to closure, including its connection to non-conformities and audits.
Difference between corrective and preventive action
Before delving into the mechanics of the process, it's essential to have a clear conceptual distinction between these two types of actions. Confusing them is one of the most common mistakes among quality teams.
A corrective action responds to a problem that has already occurred. Its objective is to eliminate the root cause of a detected non-conformity to prevent it from happening again. It's not about patching the symptom, but attacking the origin: why did the process fail? What condition allowed it? The corrective action acts on the past to protect the future.
A preventive action, on the other hand, is activated before the problem occurs. It starts from identifying a potential risk or a worrying trend and seeks to eliminate the cause of a potential non-conformity. This is where data analysis, system reviews, and proactive monitoring of quality indicators come into play.
In regulatory terms, as established by the International Organization for Standardization in its ISO 22000 and ISO 9001 standards (ISO, n.d.), management systems must include structured mechanisms for both types of actions, ensuring the system's continuous improvement and the prevention of failures before they impact product safety or quality.
In practice, many food companies only document corrective actions because they are visible and urgent. Preventive actions are pushed into the background, and that is precisely what holds back the maturity of the quality system.
Well-documented corrective and preventive actions: how to open and close them
A poorly documented action is almost as useless as never having opened it. For a corrective or preventive action to be effective, it must follow a complete and traceable cycle.
Opening the action: The starting point is always identifying the problem or risk. It must be clearly recorded who detected the situation, when, and in what context. Next, a rigorous root cause analysis is essential. Tools such as the 5 whys, the Ishikawa diagram, or fault tree analysis are useful for not stopping at the surface.
Planning the action: Once the root cause has been identified, the measures to implement, the people responsible for carrying them out, and a realistic due date are defined. Without an owner and a date, the action becomes just an intention.
Effectiveness verification: This is the step that gets skipped most often and is the most critical. Once the action has been carried out, it's necessary to check whether it has actually eliminated the cause of the problem. The verification must be documented and signed by someone with the authority to validate it.
Formal closure: The action can only be closed once effectiveness has been demonstrated. The closure must be recorded with a date, evidence, and the signature of the quality manager.
A well-documented system also makes it possible to demonstrate, in any audit, that the organization has a genuine, not merely formal, continuous improvement cycle.
Connection to non-conformities and audits
Corrective and preventive actions don't exist in isolation within the quality system. Their value multiplies when they are properly linked to the non-conformities detected and to the findings of internal and external audits.
When a non-conformity is detected — whether during the production process, in final product checks, or in an audit — the option to open an associated corrective action should be generated automatically. This traceability between the non-conformity and the action is what allows the cycle to be closed and demonstrates that the problem hasn't gone unanswered. You can dive deeper into how to manage this flow in the incident management.
In the context of audits, auditors for standards such as BRCGS Global Standards (BRCGS, n.d.) expect to find a system of corrective actions that demonstrates not only that they have been opened, but that they have been closed with verified effectiveness and have generated organizational learning. Open and unclosed actions, or actions closed without evidence of effectiveness, are warning signs that can lead to major non-conformities during the audit.
La vinculación también debe extenderse a las auditorías internas. Cada hallazgo de una auditoría interna debería traducirse en una acción —correctiva si ya se ha producido el desvío, preventiva si se detecta un riesgo potencial— y ambas deben quedar trazadas en el sistema.

Un buen sistema de gestión permite cruzar los datos de no conformidades recurrentes con las acciones abiertas y cerradas, detectando patrones y priorizando los focos de mejora más críticos. Sin esa visión global, los responsables de calidad trabajan a ciegas.
How to automate follow-up in Solved
Managing corrective and preventive actions with spreadsheets or emails creates documentation chaos that makes follow-up, traceability, and audit preparation difficult. Solved is specifically designed to solve this problem for companies in the food industry.
With Solved, you can open a corrective or preventive action in seconds, directly linked to the non-conformity or incident that caused it. The system assigns owners, sets due dates, and sends automatic alerts so that no action is ever forgotten in a drawer.
The follow-up module lets you see the status of all open actions in real time: how many are on track, how many are overdue, who the owner is, and what evidence has been attached. This dashboard is especially useful for quality managers who need an overall view of the system without wasting time manually consolidating information.
The effectiveness verification is also built into the workflow. Solved guides you to document whether the action has been effective before allowing formal closure, ensuring the cycle is always completed correctly and in an auditable way.
When an audit arrives, all the information is centralized, tracked, and available with one click: open and closed actions, their links to non-conformities, evidence of effectiveness, and due dates met. That's what makes the difference between a stressful audit and one you face with confidence.
If your goal is to build a quality system that genuinely improves with every deviation and every risk identified, corrective and preventive actions managed in Solved are the engine that makes it possible.
