Use of various charts

The Seven Basic Tools of Quality are: cause-and-effect diagrams, control charts, run charts, scatter diagrams, histograms, Pareto charts, and flow charts.

Consider the features of these tools and respond to the following:
- Identify when and why you would use these tools on an information technology project.
- Explain, giving two examples, how the use of these tools can improve the quality of an information technology project.
- Identify one difficulty of using each of these of these tools in an information technology project.

List and cite all references used.

I have outlined a response for you. Please look it over and then add what you believe are the specifics. Please look specifically at the problems with using these different charts after you have read and identified what they do. I use these charts in all projects, including IT projects and therefore identifying what is not useful about them is difficult. From your text or lectures, you may be more qualified to see what problems can occur or why they are suitable for use. For the examples, I provided one, you should use it to identify and explain a second. You might want to be more specific in how they are used in an IT project.

Control charts are used in the process itself to make sure the process is in statistical control. It uses measurement controls and a variability chart, so managers can analyze the data to make sure the project remains one of quality.

Run charts are line charts that show the performance over time. It can track different variables, and can track where improvements have been added to the project. On run charts, a line for average process movements can be added as well based on all the y values.

Flow charts are used to show how the process is supposed to flow. It will show all the steps in the process and how they fit together to make the process easier to understand with a visual representation. It is used to define the processes in a project and communicate this process to not only the project participants, but to others outside the project. It can help to standardize and improve a process by identifying where processes have issues and where more labor or resources may be needed to stop delays.

Cause and effect diagrams are also called fishbone diagrams or Ishikawa diagrams. It identifies first effects of problems in a process and the variables or issues that might be causing them. Using it helps to ...
