Evaluating PPM data in Minitab®

You can use the Minitab® application to verify the results from PPM and perform further specific Six Sigma evaluations.

You want to use the data from the process cycle time analysis described in the chapter on Process mining for further analysis in Minitab®. You decide to display the results of your evaluation using a boxplot chart.

Prerequisite

You have configured the Minitab®connection.

Procedure

  1. Display the Process mining analysis for the process cycle time described in the chapter on Process mining.
  2. Start the Minitab® application from PPM.
    1. Display the Plug-ins tab bar.
    2. Click button_start_programStart Minitab® without macro in the tab bar.

      The data is automatically transferred to Minitab® and the application is launched. The transferred data is displayed as a table in Minitab®.

  3. Create a boxplot chart with the With Groups option by selecting Graph/Boxplot in the main menu.

A boxplot chart is displayed based on your settings.

The boxplot chart confirms the significant variation between the dealers in San Francisco and Munich in terms of process cycle time, as has already been identified in the suspected deviation analysis.
