In research, data search, data processing and deduction will be more easily understood if set forth in graphical form. Broadly speaking we can know, conditions, problems that occur and the possibility of settlement roads. From the graph we can know the way researchers thought, about what is researched, how the methods used and HSIL will eventually like.
The use of graphs in research should be undertaken as a visualization of data in the form of sequence of numbers to the layman would be difficult to translate. To present a research result, it’s easier to communicate data with the drawings. Use the chart should be made as simple as possible so that no layman can understand and describe the actual condition.
Six Sigma is a project that dominates the use of statistical data which in presenting the results will always be associated with a sequence of numbers as the interpretation of problem identification, measurement, analysis, improvement and control of the object being studied.
Here we will learn some of the graphic and analytical tools related to Six Sigma project:
1. Diagram IPO (Input-Process-Output)
2. Process Flow Diagram
3. Diagram of the CE / CNX (Cause and Effect Diagram / Constant-Noise-Experiment Diagram)
4. Scatter Diagram
5. Histogram
6. Standard Operation Procedure
7. Pareto Diagram
8. Box-whisker Pot
9. Run Chart
10. Failure Mode and Effect Analysis
Some of the tools above are a tool for analysis purposes. There are many more that are recommended by experts to present the data quality analysis and data improvement.
