When identifying the underlying cause of a quality problem, it is essential to distinguish between causal factors and root causes. Causal factors are often identified as the direct causes of an issue, whereas root causes are seen as the underlying or deeper issues that contribute to the problem. In this article, we'll discuss the differences between the two, how to identify them, and how they can be used to develop effective solutions.
Causal factors are events or conditions that contribute to a problem or incident. These can include equipment malfunction, improper training, bad weather, etc. It is important to note that causal factors do not necessarily indicate a root cause of an issue; instead, they are the factors that directly lead to the problem.
Root causes are the underlying issues or conditions that contribute to a problem. These can include a lack of resources, inadequate training, poor communication, etc. Unlike causal factors, root causes are not necessarily events or conditions that directly lead to a problem; instead, they are deeper issues that require more investigation.
The below table provides a summary of the differences between causal factors and root causes:

|Can be addressed more easily and quickly||Require deeper analysis and understanding|
|May not be the primary cause of the issue||Are the primary cause of the issue|
