Nearly 100 tools are included in this compendium and have been categorized based on what they are used for. For example, tools such as flowcharts are a means of "process mapping", checklists are a "data collection" tool, histograms provide "data display and organization" information, and focus groups are a source of "idea generation". When you select a category on this page, you are provided with a list of tools and a short description of each one. Details on each tool (including steps on how to use the tools, examples of the tool's use, and advantages of the tool) can then be obtained by selecting the specific tool you wish to learn more about.
