Plus: A run chart is easy to draw and interpret.To understand how scatter diagrams work, consider the following example. It could be the relationship between a cause and an effect, between one cause and another, or even between one cause and two others. progress of the project / processes / tasks (percentage completion over time) A scatter diagram is used to show the relationship between two kinds of data.changes / trends of the process over time.Through analysis of a run chart, the following can be derived:.Run Chart: A Run Chart simply plots the data of a variable over time.After generating ideas, group them according to their affinity, or similarity. Use it to generate, organize, and consolidate information related to a product, process, complex issue, or problem. It is the organized output from a brainstorming session. 4 Conclusion: Run Chart vs Control Chart The affinity diagram organizes a large number of ideas into their natural relationships. ![]() ![]() 2 Run Chart vs Control Chart Illustrated.1 Run Chart vs Control Chart for PMP® Exam.
