Root Cause Analysis is part of an ecosystem of tools and techniques that can help organizations harness the value from their EHSQ integrated management systems.
Root Cause Analysis (RCA) is one of several tools and techniques - including Failure Mode Effects Analysis (FMEA), Control Plans and Corrective Actions (CAR or CAPA) - that can be used to uncover the reasons for safety incidents or near misses, occupational health issues, environmental issues like repeated violations and quality events like recalls and nonconformances.
These tools can be extremely valuable when used proactively -- and in conjunction with one another. Here's how they might be used together:
- Identify potential failure modes through a Process Failure Mode Effects Analysis (FMEA) exercise, OR experience actual failures or problems in operations, such as an out-of-control event initiated by Statistical Process Control (SPC).
- If the issue is significant or systematic, after containment, launch a Root Cause Analysis (RCA) to investigate how to fix the problem rather than the symptoms.
- When the root cause is determined, consider launching a Corrective Action (CAR or CAPA) to incorporate a more long-term fix.
- Record the new risk profile (Severity, Opportunity, Detection) on the FMEA and see how overall risk has changed as a result of the CAR/CAPA effort.
- Update the Control Plan with new controls for detection and/or prevention, so that this issue (and/or similar issues) don’t occur again.
Corrective and preventive actions that emerge from taking a more strategic view, rather than finding and fixing symptoms as they occur, include things like improved designs, improved standard operating procedures (SOPs), streamlined processes, improved recordkeeping, better use of data and enhanced response to emerging issues.
If you don’t use all of these tools yet, there’s no need to worry! Most organizations gradually introduce them one at a time, training staff while validating the results, to ensure that they drive value and become core capabilities. Continuous improvement, after all, is continuous.
