Assesses combined capability of a process or product. This report is available only when the Six Sigma add-on module for Minitab is installed.
By recording the number of defects observed, the number of units that passed through the system, and the number of opportunities for defects at the unit level, you can calculate a detailed roll-up analysis. This analysis shows the capability of the individual components and combined capability measures (for example, throughput yield, rolled throughput yield, DPMO, and Z), graphs showing the relative capability and control of each component, and the contributions of complexity, capability, and control to the overall capability of the system.
|When to Use||Purpose|
|Pre-project||Assist in project selection by focusing on portions of a process or a product that have high defect rates.|
|Start of project||Perform a baseline capability analysis on the process to determine the capability of the overall process and its components at the start of the project. A baseline analysis helps you set improvement goals for the project.|
|Mid-project||Perform a confirmation capability analysis after improvements have been implemented to confirm that the process performs as predicted.|
|End of project||Perform a capability analysis after implementing controls to obtain a final assessment of process capability, and also to determine whether the improvement goals of the project were attained.|
Summarized data: defects, opportunities, units.
