Among the different approaches to root cause analysis, the most commonly used method is the 5 Why Analysis, introduced by Sakichi Toyoda of Toyota Motor Corporation in the 1930s. It can be used in various business situations that involve human factors or interactions. Some of the advantages of this method include:
- It is easy to learn and use
- It allows for quick identification of the root cause
- It helps teams determine the relationship between different root causes of a problem
- It doesn’t require statistical analysis, which can make the process of identifying the root straightforward
By using the 5 Why RCA method, you can establish a culture of problem-solving by introducing a simple yet effective method that anyone can use. This can lead to a more proactive approach for problem prevention and continuous improvement of your organization’s processes.
While 5 Why is one of the most commonly used root cause analysis methods, it is typically done manually using a paper-based approach which makes it less effective. The manual process complicates the collaboration between the different team members that are conducting the investigation. It also makes documentation of the investigation much more challenging because it requires that the data and findings generated from the 5 Why analysis be added manually into the QHSE, with important files, notes and documents remaining undocumented.
