The 7 QC Tools are simple statistical tools used for problem solving. These tools were either developed in Japan or introduced to Japan by the Quality Gurus such as Deming and Juran. In terms of importance, these are the most useful. Kaoru Ishikawa has stated that these 7 tools can be used to solve 95 percent of all problems. These tools have been the foundation of Japan's astomishing industrial resurgence after the second world war. For solving quality problems seven QC tools used are Pareto Diagram, Cause & Effect Diagram ,Histogram, Control Charts , Scatter Diagrams, Graphs and Check Sheets . all this tools are important tools used widely at manufacturing field to monitor the overall operation and continuous process improvement. This tools are used to find out root causes and eliminates them , thus the manufacturing process can be improved. The modes of defects on production line are investigated through direct observation on the production line and statistical tools.
