In any business or project, problems and unexpected issues can arise. Rather than just addressing the surface-level symptoms, it's essential to dig deeper and understand the root cause of the problem.
This is where Root Cause Analysis (RCA) comes into play. By using RCA, you can identify the underlying reasons for issues and implement long-term solutions that prevent them from recurring.
Key Steps to Performing a Root Cause Analysis
Follow these basic steps to begin performing your root cause analysis for your business:
Define the Problem
Start by clearly defining the potential root issue or problem. Be specific about what happened, where it happened, and when.
Ask questions like: What is the impact of this problem? Why is it significant? How does it affect other processes or areas?
Collect Data and Evidence
Gather all relevant information about the problem. This may include records, logs, interviews, observations, or data from the affected systems.
Ensure you have a full understanding of the problem before diving into the analysis.
Identify Possible Causes
Brainstorm potential causes of the problem. Use techniques like 5 Whys or Fishbone Diagrams (Ishikawa) to help generate ideas.
-
- 5 Whys: Ask "Why?" multiple times (usually five) to peel back the layers and get to the root cause.
Example:- Why did the machine stop? -> The motor overheated.
- Why did the motor overheat? -> The cooling system failed.
- Why did the cooling system fail? -> Lack of regular maintenance.
Each "Why?" reveals a deeper cause until you arrive at the root issue.
- Fishbone Diagram: This visual tool categorizes possible causes into categories such as People, Methods, Machines, Materials, and Environment.

Analyze the Causes
Review the potential root causes and test them against the problem. Look for patterns, evidence, or correlations to identify the most likely root cause.
Validate your findings with data or facts to ensure the root cause is correctly identified. At this stage, the goal is to move beyond symptoms and focus on the most fundamental cause.
Develop and Implement Solutions
Once the root cause is identified through the impact analysis, develop a solution that addresses the problem at its source. Collaborate with relevant stakeholders to brainstorm corrective actions that will prevent the issue from happening again.
Ensure the continuous improvement solution is feasible, practical, and sustainable in the long run.
Monitor the Results
After implementing the solution, monitor the situation to ensure the problem does not recur.
Track key metrics or use feedback from stakeholders to verify that the solution is working as intended. If the issue persists, revisit the analysis to determine if another root cause or effective solution in the business process was overlooked.
Example of Root Cause Analysis Using the 5 Whys Method
Here you will find an example scenario that you could use the root cause analysis template for.
Problem: The production line stopped unexpectedly.
- Why did the production line stop?
- Because the conveyor belt jammed.
- Because the conveyor belt jammed.
- Why did the conveyor belt jam?
- Because one of the motors failed.
- Because one of the motors failed.
- Why did the motor fail?
- Because it overheated.
- Because it overheated.
- Why did the motor overheat?
- Because it wasn't receiving sufficient coolant.
- Because it wasn't receiving sufficient coolant.
- Why wasn’t the coolant supplied to the motor?
- Because the coolant pump had not been maintained according to the schedule.
Root Cause: Lack of scheduled maintenance on the coolant pump led to the motor failure, which caused the production line to stop (negative impact).
Solution: Implement and enforce a strict maintenance schedule for all cooling system components to prevent motor failures in the future business process.
Root Cause Analysis Tools
There are several tools that can help facilitate a Root Cause Analysis process:
- 5 Whys: A simple yet powerful method of asking "Why?" multiple times to drill down to the core issue in your business processes.
- Fishbone Diagram (Ishikawa): A visual tool that helps break down potential causes into various categories (e.g., people, processes, equipment).
- Pareto Analysis: A statistical technique and structured approach that identifies the major factors contributing to a problem, based on the 80/20 rule (where 80% of the problem is typically caused by 20% of the issues).
How to Use Our Root Cause Analysis Template
To make it easier for you to conduct a thorough analysis, we've provided a downloadable Root Cause Analysis template.
This business template is structured to guide you through each stage of the process, ensuring you don’t miss any crucial steps.
Step 1: Problem Definition Section
Write down a clear, concise description of the problem.
Step 2: Data Collection and Evidence
Document all the evidence and data related to the root cause investigation.
Step 3: Cause Identification (5 Whys & Fishbone Diagram)
Conduct a 5 Whys analysis and a blank Fishbone Diagram for identifying potential causes.
Step 4: Root Cause
Write the confirmed root cause based on your analysis.
Step 5: Logical Solution and Action Plan
Outline the corrective actions needed to address the root cause, including responsible parties and deadlines.
Step 6: Monitoring Results
Track the success of the implemented potential solution and monitor for any recurrence of the issue with the investigative team.

Common Pitfalls to Avoid in Root Cause Analysis
- Jumping to Conclusions: Avoid assuming the root cause without sufficient data or evidence. Always base your conclusions on facts for a lasting solution.
- Focusing on Symptoms, Not Causes: The goal of RCA is to address the underlying issue, not just the symptoms.
- Not Involving the Right People: RCA is most effective when you involve all stakeholders, especially those familiar with the processes being analyzed.
- Failing to Follow Through: Identifying the root cause is only part of the process. Ensure that corrective actions are implemented and tracked to ensure long-term success.
Performing a Root Cause Analysis is a powerful method for solving recurring issues by targeting their true source.
Remember, RCA is not just about fixing problems—it’s about improving your processes and making your impact on operations more efficient and resilient.
