Pareto Diagram
The diagram divide problem or defects based on the cause, they are graph according to priority using a bar chart on the X-axis. The Y-axis represent the % of defect or value scrap which is accumulate up to total as it moves to the right.
Cause and Effect Diagram or famously known as the fishbone/Ishikawa
These diagram are shaped like a fish with bones. Normally they are applied in the shop floor to analyze the characteristic of a process or situation and a factors that contribute to them. The four major factors are Men, Machine, Material and Method.
Histogram
The frequency data obtained from collection of measurements display a peak around certain value. The variation of quality characteristics is called " distribution". The frequency in the form of pole is referred to as histogram.
Control Chart
There are two type of variations, the inevitable variation that occur under normal conditions and those that can be trace to a cause. The later are abnormal variation. The control limit were between top and bottom line limit. Collection of data were graphed so process control are easily monitored.
Scatter Diagram
Two sets of corresponding data are plotted to form scatter diagram. The relation between these scatter diagram represent the relationship between the corresponding data.
Graphs
These comprise varieties of graph parallel bars, lines graphs, pie chart, radar and etc. These graphs are useful for data analysis and presentation.
Check sheet
Check sheet are applied at any stage of the process for routine check.
These tools will benefits you in a long run, help you to become more proficient and professional when presenting your work. Maybe even help you to sleep better at night knowing you did an awesome job!
