Six Sigma analysis tools: Pareto Diagrams Identify Priorities

[caption id="attachment_677" align="alignleft" width="300" caption="pareto diagram example"][/caption]Pareto diagram was first introduced by economists from Italy called Vilvredo Pareto in 1897 and then used Dr prosperity in the field of quality control. Pareto diagram identical to know the level of priority. At the highest frequency pareto diagrams are sorted to the lowest frequency that will be known factors are the priorities of the object being studied.

Pareto used to determine the factors that most influence on an event or process. For example, in the company's cost burden borne so great that profits are very low. Having conducted the analysis with various objects for example, material financing, employee wages, fuel, engine maintenance, and so got that finance staff are still ranked first in corporate finance.

Data with pareto model already available that the cost of workers' salaries are still high, again what to do? Still must be discussed and analyzed whether it happen extravagance in the use of labor or not. If there is waste it must be held efficiency with lean manufacturing techniques that have been recommended.

As well as in the diagram CE / CNX, the pareto analysis is also possible to see more detail on each group (especially the most significant group for more accurate we know what factors influence the group.

Six Sigma Analysis Tools: Histogram Displays the Distribution of a set of Continuous Data

A histogram is a vertical bar chart displays the distribution of That a set of continuous data. It Can Be Used to indicate the location and dispersion of the data. Histograms are also often referred to as Frequency Distribution Chart, where the presence of the histogram graph, we can easily find out frequencies in the view bar on the histogram.

In a lot of manufacturing will produce variations in the data. These data should be grouped in certain frequency intervals. This grouping is shown in the graph if the histogram will be clear. The highest stem is the highest frequency of our data analysis. Next the left of kana is data with frequency with a value below it and so on. Distribution and frequency grouping would facilitate determining the decision limits the data that is used in accordance with the needs or variations in data that must be removed.

Six Sigma analysis Tools: Scatter diagram to Show the Correlation of the X Axis and Y Axis

In a project such as six sigma manufacturing, Scatter diagrams are often used to examine the relationship between the data on one with the other data as well as to determine the level of relationship. Is there a correlation between axis X and axis Y. The objective of the scatter diagram is to correspond two sets of data and to Examine the distribution pattern.

For example, the correlation between the activity of 5S with product defects. Many people who say that 5S no correlation with product defects. But after the research with an intensive campaign 5s sharp increase product quality. It cannot be directly seen that the activity can affect the quality of 5s. However, the characteristics of 5S itself is indeed a basic activity of manufacturing that builds awareness of each employee to improve both attitude and discipline to what is done. The result can significantly reduce the defective

Six Sigma analysis tools: Diagram of CE/CNX | Cause and Effect | Constant-Noise-Experiment Diagram

Next tools are often used to analyze six sigma is a diagram of the CE / CNX or better known as Fish Bone diagram or Isikawa diagrams. The use and characteristics of fish bone diagram is
- Used to analyze the causes of a problem and finding the roots of existing problems
- Describe in detail the causes of the problem down to the smallest.
- The cause and effect diagram shows the systematic relationship Between a fixed result and the related causes.
- This diagram can be said the version details of the IPO diagram where each component in the IPO seen again the parts are more detailed.
- In general diagram of the CE / CNX is usually produced from the discussion / brainstorming.
