The tools listed—Control charts, flowcharting, histograms, Pareto charts, and scatter diagrams—are primarily used for analyzing and controlling the quality of project outputs and processes. The Control Quality process specifically involves monitoring and recording the results of executing quality activities to assess performance and recommend necessary changes. Control charts are a key tool exclusive to this process for determining if a process is stable. Histograms, Pareto charts, and scatter diagrams are also used extensively in Control Quality to identify the causes of poor quality and analyze variance.

and Scatter Diagrams as data representation tools for the Control Quality process.

"Quality Management

" discusses the seven tools of quality control

noting that tools like control charts and Pareto diagrams are used for "controlling the process." This aligns with the Control Quality process.
