Six Sigma is a methodology and a business philosophy that is aimed at enhancing the efficiency and productivity of a business to increase turnover and profits. Introduced in 1986, Motorola initiated this effort as a strategy for businesses to try and improve manufacturing processes and reduce the number of production problems that were costing Motorola millions of dollars. Since then, Six Sigma tools have amassed massive popularity among many corporate organizations because of their great economic effects on the bottom line.
Commonly used Six Sigma tools include control charts, Histograms and Pareto charts. Control charts provide information and they are also used in monitoring and controlling process performance. Histograms and Pareto charts are used to summarize data. Histograms display frequency distribution. Pareto Charts generally display a rank order of categories to give the user a visual of the highest to lowest ranked items. A Pareto chart will display differences between various groups of data and will also establish the relative importance (rank) of the different groups of data.
Mekko Graphics provides a wide range of chart types common to Six Sigma needs, including Bar Mekko or Stacked Bar Line (Pareto), Stacked Bar (Histogram), Line (Control Charts), and Scatter charts.
