The document discusses quality control (QC) tools and techniques. It describes the 7 main QC tools as cause and effect diagrams, Pareto diagrams, graphs, check sheets, histograms, scatter diagrams, and control charts. It also discusses 7 additional QC tools and various statistical and other QC methods. Finally, it outlines a 6-step process for using QC tools that involves establishing objectives, selecting a tool, collecting and analyzing data, considering results, and acting on conclusions. QC tools are presented as aids that can be used within the standard QC 7-step problem-solving formula.
