  • Summary: diagram systematically represents the relationship of specific results and cause system
  • Purpose: organizing of the relationship between the result and the cause
Tools Part 2: Check Sheet
  • Overview :( This is the same as the format of a widely used checklist)
  • Purpose: Check Point
Tool Part 3: Pareto chart
  • Summary: In stratified by item, along with arranging the frequency in the order of magnitude, showing the cumulative sum Figure
  • Purpose: To grasp the weight is large failure, utilized for ABC analysis
Tools Part 4: histogram
  • Summary: with a graphical representation of the frequency distribution of the metrological characteristics, when it is divided into the existing range of the measurement values ​​into several sections, and the bottom of each section, the area that is proportional to the frequency of the measurement values ​​belonging to the interval FIG arranged a rectangle
  • Purpose: To understand the differences in the data
Tools Part 5: scatter plot
  • Summary: The two characteristics are the horizontal and vertical axes, the graph display is made by RBI observation point
  • Objective: understand the relationship of the data to be paired
Tools Part 6: control chart
  • Summary: the value of the statistic that continuous observations or group, usually was RBIs in the order of time order or sample number, upper control limit dotted line and / or a diagram with a lower control limit line
  • Objective: discovery of abnormal values ​​from the variation
Tool that 7: graph
  • Overview: Other bar graph, line graph, such as pie charts and radar chart
  • Purpose: The discovery of a causal relationship from data

By performing the verification in these seven tools, should there be sure what you'll see something.

From there going to turn the PDCA hypothesis → run → verification is a quality management, it is a translation to become a cycle to say that going to improve the quality by continuing.
