KEY CONCEPTS

This chapter introduced us to five more quality tools which we can use to continuously improve our work processes and reduce waste.

The pie chart is a tool that graphically reveals percentages. It is an effective means of quickly conveying important information. The cause-and-effect diagram helps us understand the complex relationship between an effect (a problem or goal) and what can cause it. This diagram is used as a problem-solving tool. Histograms are important diagnostic tools because they give a clear picture of data distributions that might otherwise be difficult to visualize. Histograms are best used to determine and display the data distribution for a process. A Pareto chart is used when there is a need to focus on the most serious problems orcauses of a problem. It ranks information. The performance and stability of a process can be monitored and controlled by using a control chart. Control charts help distinguish between common and special causes of variation in a process. Control charts reveal when an abnormal change in a process has occurred and help to identify and correct the change.
