Better Process Stability Determination and Capability Reporting
Forrest Breyfogle
I help organizations enhance their KPI metric reporting and improvement system (e.g., Lean Six Sigma) so the bottom line benefits. I have author of over 15 books on business management and process improvement.
Through an alternative process stability determination and capability reporting methodology organizations can reduce firefighting and create reports that lead to the most appropriate actions or non-actions.
An organization′s traditional control charting methodology can be highlighting common-cause variability as though there were special cause events. This miss classification of measurement response levels can lead to much wasteful firefighting, as described in ″X-Bar and R Control Chart Issues and Resolution″. This article also describes a 30,000-foot-level reporting methodology that resolves this issue.
The measurement reporting techniques described in this article can also be applied to organizational Key Performance Indicator (KPI) reports. The following case study provides the how-tos for transitioning to this next generation measurement reporting technique.
The case-study article ″Reporting of an organizational KPI″ illustrates, among other things:
- Issues and resolution to control charts that erroneously identify out-of-control signals that lead to wasteful firefighting.
- How to create timely reports that provide an insightful graphical process capability/performance statement when there are no specifications and guidance for improvement efforts.
