What is root cause analysis in safety?
Root cause analysis, also known as RCA, is the investigation process following an incident. The incident may or may not have caused harm to a person or property. Incidents may not have occurred at all, but instead, someone reported a dangerous situation.
Why RCA is required?
An RCA is performed to identify what happened, why it happened and then determine what improvements or changes are required. Through the proper application of RCA, repeat problems can be eliminated. RCA methods and tools are not limited to manufacturing process problems only.
What are the types of root cause analysis?

Is a FMEA and RCA tool?
Overview: Failure Mode and Effects Analysis (FMEA) is a structured way to identify and address potential problems, or failures and their resulting effects on the system or process before an adverse event occurs. In comparison, root cause analysis (RCA) is a structured way to address problems after they occur.
How are FMEA and RCA connected?
Typically, a root cause analysis (RCA), which is also called failure analysis or accident investigation, looks back on what already happened. A failure modes effect analysis (FMEA) looks ahead to what could happen. Investigating why a problem occurred is reactive. Anticipating how something could go wrong is proactive.
How do you prepare a root cause analysis document?
A RCAT, often known as a root cause corrective action template, usually takes the following simple structure:
- A description of the event itself.
- The timeline leading up to the event (what went wrong)
- The investigative team (those involved in the procedure)
- The methods used.
