Introduction
Recurring issues drain time, resources, and customer trust. Root cause analysis (RCA) is a systematic method for identifying the underlying cause of a problem, not just its symptoms. When used correctly, RCA helps organizations reduce risk, improve quality, and create sustainable solutions, especially when paired with simulation tools to test potential fixes.
What is Root Cause Analysis?
Root cause analysis is a structured problem-solving approach used to identify the origin of an issue. Instead of repeatedly treating symptoms, RCA digs deep to uncover the “why” behind a problem, enabling organizations to implement corrective actions that prevent recurrence.
RCA is foundational in quality management systems and is essential for compliance in industries like life sciences, aerospace, and manufacturing.
When Should You Use Root Cause Analysis?
You should conduct a root cause analysis when:
A problem keeps recurring
An incident causes significant downtime, cost, or risk
Regulatory requirements demand a thorough investigation
CAPA processes are triggered in a compliance framework
5 Key Steps to Root Cause Analysis
Clearly Define the Problem
Identify the who, what, when, where, and how of the issue. Include measurable impacts.
Gather Evidence
Collect data from process logs, reports, and interviews to establish timelines and contributing factors.
Identify Possible Root Causes
Apply tools like:
- 5 Whys Analysis
- Fishbone (Ishikawa) Diagrams
- FMEA (Failure Mode and Effects Analysis)
- Fault Tree Analysis
Validate the Root Cause
Verify that the identified cause explains the problem and is supported by data.
Design and Simulate Corrective Actions
Use BPMN 2.0 process simulation to test how proposed changes affect the larger system — before implementation.
How Process Simulation Supports RCA
Simulation takes root cause analysis from theory to validation. By modeling your corrective actions through BPMN 2.0 simulations, you can:
Forecast the impact of changes
Identify unintended consequences
Prevent shifting bottlenecks
Confirm the fix will actually solve the problem
RCA Tools Comparison
Tool | Purpose | Best Use Case |
|---|---|---|
| 5 Whys | Simple analysis | Manufacturing or operations |
| Fishbone Diagram | Cause categorization | Complex service issues |
| FMEA | Risk anticipation | Product design, life sciences |
| Process Simulation | Testing solutions | Process changes, compliance |
