What are the types of Root Cause Analysis?

The correct choice identifies two widely used techniques in Root Cause Analysis: the 5 Whys and the fishbone diagram.

The 5 Whys method is a simple yet powerful technique for identifying the root cause of a problem by asking "why" multiple times—typically five—to drill down to the underlying issue. This approach encourages users to explore the cause-and-effect relationships underlying a particular problem, ultimately leading to deeper insights and solutions.

The fishbone diagram, also known as the Ishikawa or cause-and-effect diagram, visually organizes potential causes of a problem into categories. This structured approach allows teams to brainstorm and categorize potential factors contributing to an issue, facilitating a discussion that can uncover numerous root causes.

Together, these tools create a robust framework for understanding complex problems in a systematic way, making it easier for teams to develop effective solutions. The combination of both techniques is particularly useful in manufacturing, quality improvement, and other operational contexts, emphasizing the interconnectivity of various components that can lead to a particular outcome.

The other options, while they reference various analysis or brainstorming methods, do not hold the same level of recognition or application as the 5 Whys and fishbone diagram in Root Cause Analysis. Thus, they are less relevant in the
