Which tool is commonly used for identifying the root cause of a problem?

Flowchart
Histogram
Pareto chart
Fishbone diagram

The correct answer is: Flowchart

A flowchart is commonly used for identifying the root cause of a problem because it provides a clear visual representation of the steps in a process. By mapping out each step in the process, potential areas of inefficiency, errors, or bottlenecks can be easily identified. Flowcharts help in logically organizing information and determining the sequence of events, which is crucial in identifying the root cause of a problem. On the other hand, the other options are not specifically designed for identifying the root cause of a problem: - Histograms are used to display the distribution of data and show the frequency of occurrences within a specific range. - Pareto charts are used to prioritize problems or issues based on the frequency of occurrence. - Fishbone diagrams, also known as Ishikawa diagrams, are used to identify potential causes of a problem by categorizing them into different groups.
