Root Cause Analysis in Maintenance Management is essential to identify and correct equipment failures, ensuring greater reliability and availability of assets. As a result, managers are able to prevent future problems and increase operational efficiency. Therefore, adopting appropriate tools and methodologies is indispensable.
Why Perform Root Cause Analysis?
Even with strategies such as Reliability Centered Maintenance (RCM) and Total Productive Maintenance (TPM), unwanted and unexpected failures can still arise. When this happens, it is crucial to use reactive tools, such as Root Cause Analysis, to understand the source of the problem and implement corrective actions that prevent its recurrence.
In addition, this analysis allows you to verify whether there were failures in the previously adopted maintenance strategies. In this way, it is possible to promote continuous improvements in process management and asset reliability.

The Importance of Root Cause Analysis
Root Cause Analysis plays a crucial role in identifying bottlenecks and failures in the Maintenance Management system. Consequently, it contributes to the improvement of equipment reliability and availability.
For example, by investigating the source of a failure, it is possible to determine whether factors such as inadequate methods, insufficient labor, or problems with materials are impacting the results. With this, strategies can be adjusted to achieve more efficient processes.

Top Tools for Root Cause Analysis
There are several tools that can be used to perform a Root Cause Analysis effectively. Among them:
1. 5 Whys Methodology (5-Why)
- It examines a failure in detail, questioning “why” successively until it reaches the main cause.
- Entretanto, nem sempre são necessários exatamente cinco “porquês”; em alguns casos, menos ou mais podem ser suficientes.
👉 Confira mais sobre a Metodologia 5 Porquês.
2. Ishikawa Diagram (Fishbone)
- It stratifies the possible causes of a failure into categories such as machine, method, workmanship, material, environment, and measurements.
- Além disso, ajuda a identificar causas contribuintes que podem estar impactando o problema.

3. Fault Tree
- It allows you to visualize the causes at hierarchical levels, organizing the information in a logical way.
- For example, branches can reveal multiple interconnected factors that contributed to the failure.
4. Method of Analysis and Problem Solving (MASP)
- Based on the PDCA cycle, this method includes:
- Identification of the problem.
- Detailed analysis.
- Creation and execution of an action plan.
- Checking the effectiveness of actions and standardization of processes.

How to Ensure Success in Root Cause Analysisz
After completing the analysis:
- Share the results with the team, explaining the root cause and the corrective actions that will be taken.
- Review important documents such as the criticality matrix, maintenance plans, and standard operating procedures.
- Standardize processes to prevent the problem from occurring again.
Also, remember to monitor the effectiveness of the actions implemented. If necessary, adjust strategies to ensure consistent results.
Benefits of Root Cause Analysis in Maintenance Management
- Accurate identification of root causes of failures.
- Reduction of unexpected downtime and associated costs.
- Continuous improvement of asset reliability and availability.
- Promotion of a culture of learning and evolution among teams.
