CONCLUSIONS
- Made significant fundamental changes to the learning process i1;1 ComEd's Engineering.
+. Will monitor performance using the Significant Events, Repeat Event Metric and other indicators such as the Self-Identification Ratio for: Engineering PIFs.
- Existing data and trends are in the correct direction. Still have declining performance trend at Quad Cities.
