In this chapter, we have discussed 13 quality tools, some in great detail and a few on an introductory basis. Your challenge will be selecting the appropriate tool (or tools) for the task at hand. This can be confusing, especially at first. For that reason, we have included Table 15.2, a functionality matrix for the tools. It is by no means complete in terms of the possible uses of the tools or tasks that may be required, but it illustrates the common functionality of our tools. For example, if your task is to obtain data from a group of customers, the matrix will point you to the survey. If you are looking for something that will provide useable information in graphic form even as the data are being collected, then the matrix suggests a check sheet, Pareto chart, or run chart. Your selection will be determined by which tool you think will best satisfy your requirement. Note that most of the tools are useful in more than one situation. Your knowledge of the task will often make the selection clear, although there may also be some trial and error involved initially. The matrix is intended to illustrate the kinds of functions that may be appropriate for the tools. Once you start using them, you will find the selection to be virtually automatic.
