Knowing how to perform a root cause analysis helps businesses identify and eliminate the root cause of a problem, rather than just treating the symptoms, only for the problem to resurface again later.
Conducting a root cause analysis can help businesses to save time and resources, and improve processes, products, and services.
This article provides a simple step-by-step guide on how to conduct a root cause analysis for your business.
The analysis should preferably be conducted with representative employees (known as internal stakeholders) who are engaged in the process/es under scrutiny.
Many businesses benefit from the assistance of a consultant with expertise in the exercise for timeliness and reduced costs.
How to Perform a Root Cause Analysis – First Understand the Problem
A Root Cause Analysis (RCA) is a systematic and structured approach to identifying the underlying causes of a problem or issue in a business. It is only effective if you fully understand the problem that you are trying to solve and you apply the proper tools and techniques.
It is the first step in the method and covers the steps to identify the problem, its impact on the business, gather relevant data and information and create a problem statement.
Identify the Problem
The first step is to identify the problem that you want to address. This may appear obvious, but it’s important to define the problem in a way that is clear and specific. The problem may be a case of non-compliance with a regulation or an internal quality control.
Other problems could come from recommendations from an internal audit.
You can use tools like process mapping and flowcharts to help identify the problem and its scope. Involve stakeholders in the problem identification process, to ensure that you have a comprehensive understanding of the problem.
Assess the Impact
This involves identifying the effects of the problem on the business, such as reduced productivity, increased costs, or decreased customer satisfaction.
Gather Relevant Data and Information
Gather all relevant data and information about the problem. This may include surveys, customer complaints and feedback, sales data, process documentation, and other relevant information.
Gather both qualitative and quantitative data, to provide a complete picture of the problem.
Create a Problem Statement
Once you have identified the problem and its impact on the business and gathered all relevant data and information, you can create a problem statement.
A problem statement should clearly and concisely describe the problem and its impact on the business. It should include the scope of the problem, the consequences of the problem, and the urgency of the problem.
Identify Potential Causes
To identify potential causes you will need to conduct a brainstorming session with the identified internal stakeholders to narrow down the list of potential immediate (proximate) and underlying causes.
TIP: Do not be quick to stop at the immediate causes. Use the 5 Why technique to drill down further to find the underlying causes.
Proximate causes are the immediate events or actions that led to the problem, while underlying causes are the systemic issues that contributed to the problem.
By considering both proximate and underlying causes, it is easier to identify the root cause of the problem to address it effectively.
Analyze Causes
After identifying potential causes, the next step is to analyze them to determine the root cause of the problem.
How to Perform a Root Cause Analysis – Use Tools to Analyze Causes
Fishbone diagrams and 5 Whys are two commonly used tools for analyzing causes. Fishbone diagrams help to visually organize potential causes into categories like people, processes, or technology.
5 Whys is a technique that involves asking “why” five times to identify the underlying cause of a problem.
Use and Analyze Relevant Data to Identify Root Causes
Data is an essential component of conducting a root cause analysis. By collecting and analyzing relevant data, you can gain insights into the root cause of the problem.
Data can come from various sources, including customer feedback, employee surveys, or operational metrics. By using data to support your analysis, you can make more informed decisions and identify the root cause of the problem accurately.
Common Mistakes in the Analysis Process
There are several common mistakes that businesses make when conducting a root cause analysis. These include relying on assumptions or biases, not involving the right stakeholders, or failing to prioritize potential causes effectively.
To avoid these mistakes, approach the analysis process with an open mind, involve diverse stakeholders, and prioritize potential causes based on their frequency or impact.
Develop Solutions
After identifying the root cause of the problem, the next step is to develop solutions that address the issue.
Techniques to Generate Possible Solutions
Again, there are various techniques for generating possible solutions, such as brainstorming, mind mapping, or SWOT analysis. Brainstorming involves generating a large number of potential solutions without evaluating them.
Mind mapping is a technique that involves visually organizing ideas and connections between them.
A SWOT analysis is a tool used to identify the strengths, weaknesses, opportunities, and threats associated with a particular solution. By using these techniques, you can generate a diverse range of possible solutions.
Evaluate and Prioritize Potential Solutions
One way to do this is by creating a matrix that considers the feasibility, impact, and cost of each solution. This matrix can help you objectively evaluate each solution and identify the most effective one. Review stakeholder feedback and potential risks associated with each solution.
Create Your Execution Plan
This action plan should include specific steps, timelines, and responsibilities for each step. You must communicate the action plan to stakeholders and ensure that everyone is aware of their role in the implementation process.
Implement and Monitor
After creating an action plan for implementing the selected solution, the next step is to effectively implement the solution in the business.
It involves techniques for effectively implementing solutions, establishing a system for monitoring the effectiveness of the solution, and continuous improvement and refinement of the solution.
Effective implementation of the solution is critical to address the root cause of the problem. To do this, ensure that everyone involved in the process is aware of their responsibilities and timelines.
This can be accomplished by setting up regular meetings and providing progress reports to stakeholders. Also provide training to employees to ensure that they can carry out their responsibilities effectively.
Establishing a system for monitoring the effectiveness of the solution is essential to ensure that the problem has been addressed successfully. This can be done by setting up key performance indicators (KPIs) that measure the effectiveness of the solution.
KPIs should be measurable, specific, and achievable. Monitor the KPIs regularly to identify any potential issues and take corrective action.
Continuous Improvement and Refinement of the Solution
Continuous improvement and refinement of the solution are necessary to ensure that the solution remains effective in the long term.
This can be done by collecting feedback from stakeholders, monitoring KPIs, and identifying any areas for improvement. Ensure that you keep up to date with industry best practices and new technologies to identify opportunities for improvement.
Conclusion – How to Do a Root Cause Analysis
Some problems in a business require a root cause analysis. Knowing how to perform a root cause analysis is beneficial, but it can get a bit too technical for most small business owners.
Hiring a competent consultant to work with you will ensure that you get the analysis done efficiently within a short timeframe even while day-to-day activities are being conducted.
