Step-by-Step Guide: Root Cause Analysis Example for Effective Problem Solving

When faced with a problem, it’s important to not just treat the symptoms but to identify and address the underlying root cause. This is where root cause analysis comes into play. Root cause analysis is a systematic approach used to determine the fundamental reason behind an issue or problem. In this article, we will provide a step-by-step guide on how to conduct a root cause analysis, using a real-life example to illustrate each step.

Step 1: Define the Problem

The first step in conducting a root cause analysis is to clearly define the problem you want to solve. It’s important to be specific and concise when defining the problem, as this will help focus your analysis efforts. For example, let’s say you work for a manufacturing company that has been experiencing an increase in product defects. The problem statement could be defined as “Increase in product defects leading to customer complaints and decreased sales.”

Step 2: Gather Data

Once you have defined the problem, it’s time to gather data related to the issue at hand. This can include customer feedback, production records, quality control reports, and any other relevant information. In our example of increased product defects, you might gather data on defect rates over time, customer complaints received, and any changes made in the production process during that period.

Step 3: Identify Possible Causes


With the data in hand, it’s time to identify potential causes of the problem. Brainstorming sessions and group discussions can be helpful during this step. In our example of increased product defects, possible causes could include faulty machinery or equipment, inadequate employee training, changes in raw materials or suppliers.

Step 4: Analyze and Determine Root Cause(s)


Once potential causes have been identified, it’s time to analyze them further and determine which one(s) are the root cause(s) of the problem. This can involve using tools such as the 5 Whys technique, which involves asking “why” multiple times to get to the underlying cause. In our example, if faulty machinery is identified as a potential cause, you would ask “why is the machinery faulty?” and continue asking “why” until you reach the root cause, such as lack of regular maintenance.

It’s important to note that there may be multiple root causes contributing to a problem. In our example, it’s possible that both faulty machinery and inadequate employee training are root causes of increased product defects.



Root cause analysis is a powerful tool for effective problem-solving. By following these four steps – defining the problem, gathering data, identifying possible causes, and analyzing and determining root cause(s) – you can uncover the underlying reasons behind an issue and implement targeted solutions. Remember that conducting a root cause analysis requires time and effort but can ultimately lead to long-term improvements in your business processes. So next time you encounter a problem, don’t just treat the symptoms; dig deeper with root cause analysis.
