A complete use case provides you with an overview of how you can use PPM to run your Six Sigma projects.
Scenario
The management decides to improve the billing process flows using the Six Sigma method and to subsequently monitor them regularly using appropriate means. The process analysis is based on the current billing data from the 2006 fiscal year.
The implementation of the Six Sigma project with PPM is described using the following examples.
Use case overview
Project phase: Measure processes
You carry out an analysis of the actual situation to establish the average process cycle time for billing.
Project phase: Analyze processes
You then analyze the distribution of the corresponding process instances in a distribution chart.
An outlier analysis returns the process instances with the longest process cycle times.
You can use Process mining to identify particular suspected deviations in terms of selected dimensions in the affected processes.
In an EPC benchmark, you can perform a detailed comparison of the process instances with the longest and shortest process cycle time. This enables you to derive possible actions to reduce the cycle times.
A boxplot chart in Minitab enables you to verify your analyses from PPM.
An analysis of the process capability in Minitab provides you with information about how reliably the specified targets can be achieved.
Project phase: Control processes
You can then use a time series chart and a control chart from Minitab to monitor whether the improvement measures have brought about the desired results.
To achieve sustainable control, you integrate your analyses in Performance Dashboard and regularly query the analysis results.
