Which chart is used to identify process flow issues?

The flowchart is the correct choice for identifying process flow issues because it visually represents the sequence of steps in a process. This diagram helps to illustrate how different elements of a process interact with each other and can reveal bottlenecks, redundancies, or inefficiencies that may not be apparent in raw data.

By laying out the steps in a clear and organized manner, a flowchart allows teams to analyze the process comprehensively. It can pinpoint where transitions fail or where delays occur, enabling targeted improvements. When looking to enhance efficiency or troubleshoot problems within a process, a flowchart serves as an effective tool to not only visualize the current state but to also facilitate discussions around process optimization.

In contrast, bar charts and histograms summarize data distributions but do not provide insights into specific process step interactions or flows, making them less suitable for analyzing process issues. Control charts monitor process variation over time and are essential for maintaining quality but do not directly highlight flow-related problems.
