Root Cause Analysis
Root Cause Analysis (RCA) helps you uncover the true source of a problem, allowing you to address it at its core and prevent it from reoccurring. Dive in to learn how this powerful method can drive lasting solutions!
What is Root Cause Analysis?
Root Cause Analysis (RCA) is a way to find out why a problem happened. By finding the main cause, it helps fix the issue and stop it from happening again.
Top 10 Tools and Techniques for Root Cause Analysis
Effective Root Cause Analysis (RCA) requires the use of various techniques to uncover the underlying issues that cause customer complaints. Here are ten comprehensive methods, along with detailed explanations on how to apply each technique to gain valuable insights, including the mental and cultural approaches that can enhance their effectiveness.
1. 5 Whys Technique
Description: The 5 Whys technique is a straightforward yet powerful tool used in root cause analysis. It involves asking “why?” multiple times, typically five, to dig down to the root cause of a problem. This method helps teams move beyond superficial answers and uncover deeper, systemic issues that need to be addressed.
How to Use It: Start with the problem statement, then ask “why?” the problem occurred. For each subsequent answer, ask “why?” again, until you reach a root cause that no longer leads to another “why.” It’s important to maintain an open and non-judgmental mindset during this process, encouraging team members to think critically and explore all possible explanations.
Applying the 5 Whys - Example 1: If a customer complains about slow service, the first “why” might identify that staff were busy. Asking “why?” again might reveal understaffing as the root issue. Further questioning could uncover that scheduling practices need improvement.
Applying the 5 Whys - Example 2: If a product is consistently delivered late, the first “why” might reveal that the production process is delayed. Asking “why?” again could uncover that a key supplier is unreliable. Further questioning might show that the supplier was chosen for cost reasons, without considering delivery reliability, indicating a need for better supplier selection criteria.
In both examples, the 5 Whys technique is used as part of a broader root cause analysis to identify the underlying issues and implement effective solutions.

1. Identify the Problem: Slow Service Complaint
• What was found: A customer has complained about slow service. This is the surface issue that needs deeper investigation.
2. First Why: Why Was the Service Slow?
• What was found: The initial reason identified was that the staff were busy, indicating a high workload at that time.
3. Second Why: Why Were the Staff So Busy?
• What was found: It was discovered that the restaurant was understaffed during the busy period, leading to overwhelmed employees.
4. Third Why: Why Was the Restaurant Understaffed?
• What was found: The scheduling practices were found to be inadequate, with not enough staff assigned during peak hours.
5. Fourth Why: Why Are Scheduling Practices Inadequate?
• What was found: Further analysis revealed that there was no system in place to predict peak times accurately, resulting in poor planning and staff allocation.
This process tracks back from the initial problem to uncover deeper issues, leading to the root cause: inadequate scheduling practices due to a lack of peak time prediction.
2. Fishbone Diagram (Ishikawa)
Description: The Fishbone Diagram, also known as the Ishikawa or cause-and-effect diagram, is a visual tool commonly used in root cause analysis. It helps teams categorize and systematically examine potential causes of a problem. The diagram typically breaks down causes into categories such as People, Processes, Equipment, Materials, Environment, and Management.
How to Use It: Start by writing the problem at the “head” of the fishbone. From the main spine of the diagram, draw “bones” that represent each category of potential causes. Within each category, brainstorm possible causes and add them as smaller bones branching off the main bones. This technique encourages a comprehensive view of the problem, helping to uncover hidden interactions between different factors and contributing to a thorough root cause analysis.
Example: In a manufacturing setting, a Fishbone Diagram might be used to explore why a product consistently fails quality checks. Possible causes could include machine calibration issues (Equipment), insufficient training (People), and poor-quality raw materials (Materials).
3. Pareto Analysis
Description: Pareto Analysis is a technique used in root cause analysis that is based on the Pareto Principle, which suggests that 80% of problems are typically caused by 20% of the causes. This method helps prioritise the most significant issues by identifying the “vital few” causes that contribute to the majority of problems.
How to Use It: Start by collecting data on the frequency of various problems or complaints. Rank these issues in order of occurrence and calculate the cumulative percentage. The goal is to pinpoint the small number of causes that are responsible for the majority of the problems. It’s important to create a culture where focusing on these “vital few” doesn’t mean ignoring lesser issues but rather prioritising resources effectively as part of a thorough root cause analysis.
Example: A customer service department might discover that 80% of complaints stem from just a few recurring issues, such as billing errors and long wait times. By focusing on these key areas as part of their root cause analysis, the department can implement targeted solutions that lead to significant improvements in overall customer satisfaction.
4. Failure Mode and Effects Analysis (FMEA)
Description: Failure Mode and Effects Analysis (FMEA) is a systematic approach used in root cause analysis to identify potential failure modes within a process and assess their impact, likelihood, and detectability. The goal of FMEA is to prioritize the most critical failures so that preventative measures can be implemented before they occur.
How to Use It: List all the steps in a process and identify potential failure modes for each step. For each failure mode, assess its severity, occurrence, and detection using a scoring system. Multiply these scores to get a Risk Priority Number (RPN). Focus on failure modes with the highest RPNs first. This technique benefits from a detailed, meticulous approach and works best in a culture that values thoroughness and proactive risk management.
Example: A financial services firm might use FMEA to evaluate risks in a new online payment system. Potential failure modes could include system downtime or incorrect transaction processing. By using FMEA in their root cause analysis, the firm can identify these risks early and implement safeguards to prevent them, ensuring the system’s reliability and customer satisfaction.
5. Fault Tree Analysis (FTA)
Description: Fault Tree Analysis (FTA) is a top-down, deductive analysis technique commonly used in root cause analysis to identify various factors leading to a specific failure. FTA employs a tree diagram to map out these factors, starting with the undesired event at the top.
How to Use It: Begin with the primary failure or problem at the top of the tree. From there, branch out to identify the direct causes, then continue branching to uncover secondary and tertiary causes. FTA is highly effective in complex systems where failures may be the result of multiple interacting factors. Teams need to be detail-oriented and systematic, ensuring no potential cause is overlooked.
Example: In an IT environment, FTA might be used to trace the root cause analysis of a system outage. The analysis could reveal that the outage was due to a combination of factors, including software bugs, hardware failures, and human error. By mapping out these causes with FTA, the team can identify and address the underlying issues to prevent future outages.
6. Current Reality Tree (CRT)
Description: The Current Reality Tree (CRT) technique, part of the Theory of Constraints, is a powerful tool used in root cause analysis to map out cause-and-effect relationships between various problems within a system. CRT helps identify core issues that lead to multiple undesirable effects.
How to Use It: Start by listing all the problems or undesirable effects currently observed. Then, work backward to identify the root causes of these problems, drawing connections between them. The CRT helps highlight how seemingly unrelated issues may stem from the same root cause. This technique benefits from a collaborative culture where team members are encouraged to think critically and challenge assumptions.
Example: A retail company experiencing declining sales, stock shortages, and customer complaints might use CRT to discover that all these issues are linked to poor inventory management practices. By identifying this core issue through CRT and root cause analysis, the company can implement targeted solutions to address these widespread problems.
7. Root Cause Mapping
Description: Root Cause Mapping is a visual method used in root cause analysis that combines elements of other RCA techniques, such as the 5 Whys and Fishbone Diagrams, to create a comprehensive map of all possible causes of a problem. This approach provides a detailed and structured way to explore and understand complex issues.
How to Use It: Start with the main problem in the center of the map. Use branches to explore primary causes, and further branches to delve into secondary causes. This method encourages a broad exploration of possible causes, helping teams to uncover deep-seated issues that might otherwise be missed. A collaborative mindset is key, with open discussions and brainstorming sessions to ensure all possible causes are considered.
Example: A call center might use Root Cause Mapping to address high employee turnover. By mapping out the issue, they could identify several contributing factors, such as lack of career progression, inadequate training, and poor management practices. Through this comprehensive root cause analysis, the call center can develop targeted strategies to reduce turnover and improve employee satisfaction.
8. Scatter Diagrams
Description: Scatter Diagrams are a valuable tool in root cause analysis used to identify relationships between two variables that might be contributing to a problem. By plotting these variables on a graph, businesses can determine if there’s a correlation that could indicate a root cause.
How to Use It: Collect data on the two variables you want to explore, then plot them on a graph with one variable on the x-axis and the other on the y-axis. Look for patterns or trends that suggest a relationship. This technique requires analytical thinking and a willingness to explore various hypotheses. It’s also important to maintain an open mind, as corelation does not always imply causation.
Example: A hotel chain might use a scatter diagram to investigate the relationship between customer satisfaction scores and the number of staff on duty. By analysing the scatter diagram, they might discover that lower staffing levels correlate with lower satisfaction scores. This insight can guide further root cause analysis to determine whether staffing levels are indeed contributing to lower customer satisfaction and how best to address it.
9. Kaizen Method
Description: The Kaizen Method, which means “continuous improvement” in Japanese, is an approach that focuses on making small, incremental changes that collectively address root causes over time. It’s a philosophy that encourages all employees to contribute to the process of improvement, which is crucial in effective root cause analysis.
How to Use It: Implement daily or weekly Kaizen meetings where team members can discuss problems, suggest improvements, and track progress. Focus on making small changes that are easy to implement and can lead to gradual improvements. Kaizen thrives in a culture of continuous learning and employee empowerment, where everyone is encouraged to contribute ideas.
Example: In a manufacturing plant, Kaizen might involve workers suggesting and implementing small changes to their workflow, such as rearranging tools or adjusting machine settings, to improve efficiency and reduce errors. Over time, these small adjustments, guided by root cause analysis, can lead to significant improvements in overall productivity and quality.
10. Brainstorming Sessions
Description: Brainstorming is a collaborative technique used in root cause analysis where a group of people come together to generate ideas and potential causes for a problem. It encourages creative thinking and diverse perspectives, helping to uncover root causes that might not be immediately obvious.
How to Use It: Gather a diverse group of stakeholders and clearly define the problem at the start of the session. Encourage everyone to share their ideas, no matter how out-of-the-box they may seem. After generating a list of possible causes, the group can prioritise the most likely ones for further investigation. Effective brainstorming requires a culture of openness and respect, where all ideas are valued and considered.
Example: A tech company experiencing frequent product delays might hold a brainstorming session with team members from different departments to explore potential causes. Ideas might include supply chain issues, development bottlenecks, or miscommunication between teams. By leveraging the diverse perspectives during brainstorming, the company can conduct a more thorough root cause analysis and identify the key factors contributing to the delays.
5 tips to run more effective brain storming sessions
-
Before the brainstorming session begins, define the goals and objectives. Are you looking to solve a specific problem, generate new ideas for a project, or improve a process? Communicate these objectives clearly to all participants so they come prepared with relevant ideas and insights. Having a clear focus helps keep the discussion on track and ensures that the session is productive.
-
Encourage everyone to participate by fostering an atmosphere where all ideas are welcomed without judgment. Make it clear that there are no “bad” ideas during brainstorming. This open environment helps participants feel comfortable sharing their thoughts and contributes to a diverse range of ideas. To prevent dominant voices from overshadowing others, consider using techniques like round-robin brainstorming, where everyone gets a turn to speak.
-
Incorporate visual aids such as whiteboards, sticky notes, or digital tools like Miro or Trello to help organize thoughts and ideas. Visual representation can help participants see connections between different ideas and foster creativity. Encourage participants to sketch, draw, or map out their ideas, making the session more engaging and interactive.
-
Brainstorming sessions can quickly become unproductive if they run too long or deviate from the main topic. Set a specific timeframe for the session and for each segment of the discussion. Use a timer if necessary to ensure the team stays on track and focuses on generating actionable ideas rather than getting stuck on one point.
-
At the end of the brainstorming session, summarise the key points, ideas, and suggestions. Identify the most viable ideas and assign action items to specific team members. Create a follow-up plan to review the progress of these ideas in future meetings. This approach ensures that the brainstorming session leads to tangible outcomes and maintains momentum.
By applying these Root Cause Analysis techniques, businesses can gain a deep understanding of the underlying causes of customer complaints and operational failures. Each method provides a unique perspective, allowing teams to identify and address root causes effectively. This approach leads to improved processes, enhanced customer satisfaction, and long-term success. By thoroughly exploring and resolving root causes, businesses not only fix the immediate problems but also create a stronger foundation for future growth and resilience.

5 Whys Complaint Root Cause Analysis Example: Complaints About Late Deliveries
Problem: Customers are complaining about late deliveries.
What we can learn from this example:
Monitor delivery times to identify logistical delays and implement tracking systems.
Optimise warehouse loading processes to reduce wait times and improve efficiency.
Provide clear communication and training to warehouse staff on prioritising and loading orders.
Review and upgrade the order management system to ensure it effectively prioritises urgent deliveries and allows real-time updates.
Continuously gather feedback from staff and customers to refine processes and systems, preventing similar issues from recurring.
This example shows how a surface-level problem, late deliveries, might initially appear to be caused by one issue, but further analysis reveals deeper, more systemic problems. By asking “why” multiple times, a company can uncover and address the true root cause of complaints, leading to long-term improvements in their service.
Implementing Solutions After Root Cause Analysis
Identifying the root cause of a complaint is only the first step; the real impact comes from implementing effective solutions that address the issue comprehensively. The key to successful implementation lies in translating the insights gained from Root Cause Analysis (RCA) into actionable changes within the organisation. These changes should be tailored to directly target the identified root causes, ensuring that the problem does not recur. Below are some strategies for implementing solutions:
Process Redesign:
Explanation: If a flawed or inefficient process is identified as the root cause, it is essential to redesign that process to eliminate bottlenecks, streamline operations, and enhance overall efficiency. This might involve re-evaluating workflows, reallocating resources, or integrating new technologies.
Example: In a customer service environment, if long wait times are identified as a root cause of complaints, the process redesign might involve introducing automated call distribution, increasing staffing during peak hours, or simplifying the process for resolving customer inquiries. These changes can significantly reduce customer frustration and improve service delivery.
Training and Development:
Explanation: When RCA reveals that a lack of training or inadequate staff skills are contributing to customer complaints, it’s vital to invest in comprehensive training programmes. These programmes should be designed to equip employees with the necessary skills and knowledge to perform their roles effectively.
Example: If RCA identifies that customer complaints are due to inconsistent service delivery, a targeted training programme can be implemented to ensure that all staff members understand and adhere to best practices in customer service. This could include role-playing exercises, customer interaction workshops, and ongoing professional development opportunities.
Product Improvement:
Explanation: For complaints related to product defects or shortcomings, collaborating with the product development team is crucial. The goal is to enhance product quality by addressing the specific issues that have been identified.
Example: If a high number of customer complaints stem from a particular product malfunctioning, the product development team might conduct a thorough review and make necessary adjustments to the design or manufacturing process. This could involve selecting higher-quality materials, improving assembly techniques, or introducing more rigorous quality control measures.
Improved Communication:
Explanation: Clear and consistent communication is essential for managing customer expectations and preventing misunderstandings. RCA may reveal that communication breakdowns are a significant source of complaints, making it imperative to establish or enhance communication protocols.
Example: If customers frequently complain about not being kept informed during a service process, the company might implement a communication strategy that includes regular updates via email, SMS, or phone calls. This could also involve setting up a dedicated customer portal where clients can track the progress of their service requests or orders in real-time.
Measuring the Success of Root Cause Analysis
The effectiveness of the RCA process is determined by the tangible improvements it brings to the organisation, particularly in reducing customer complaints and enhancing overall performance. To gauge the success of RCA, businesses should employ a variety of metrics and feedback mechanisms. These measurements not only confirm that the implemented solutions are working but also provide insights for further refinement and continuous improvement.
Reduction in Complaints:
Explanation: One of the most direct indicators of successful RCA is a noticeable reduction in the number of recurring complaints. By tracking complaint volumes over time, businesses can determine whether the solutions derived from RCA have effectively addressed the root causes.
Example: If a company implements changes based on RCA and sees a steady decline in the specific complaints that were targeted, it can be confident that the RCA process was effective. This metric should be monitored continuously to ensure sustained improvement.
Customer Satisfaction Scores:
Explanation: Customer satisfaction is a critical measure of how well the business meets customer expectations. Tools like customer surveys, Net Promoter Scores (NPS), and Customer Satisfaction (CSAT) scores provide valuable feedback on the impact of RCA efforts.
Example: After implementing RCA-driven changes, a company might see an increase in its NPS, indicating that customers are more likely to recommend the business to others. Similarly, higher CSAT scores would suggest that customers are happier with the service they receive, reflecting the positive impact of the changes.
Process Efficiency Metrics:
Explanation: Improved process efficiency is another key outcome of successful RCA. Tracking key performance indicators (KPIs) related to process efficiency, such as turnaround times, error rates, and resource utilization, helps to quantify the benefits of the implemented changes.
Example: If a business redesigns its complaint handling process and notices a reduction in the time it takes to resolve complaints or a decrease in errors during service delivery, these improvements can be directly attributed to effective RCA.
Cost Savings:
Explanation: Effective RCA not only improves customer satisfaction and process efficiency but also leads to significant cost savings. By reducing the number of complaints, product returns, or service failures, businesses can lower the costs associated with rework, refunds, and customer retention efforts.
Example: A company might find that after addressing the root causes of product defects, the costs associated with returns and repairs decrease significantly. These cost savings contribute to the overall profitability of the business, making RCA a valuable investment in long-term success.
