Figure 17.13 Adjust Production Counts
Tip: If you would rather enter specific numbers than manually adjust the bars, select Spreadsheet
Configuration of Risk Sets from the Forecast report red triangle menu. “Spreadsheet Configuration of Risk
Sets” on page 314 describes this feature.
Adjust the Existing Risk Set
Right-clicking a blue bar and selecting Exclude removes that risk set from the forecast results. You can then
right-click and select Include to return that data to the risk set.
Forecast Failures
When you adjust production in the left graph, the right graph is updated to estimate future failures
(Figure 17.14). Dragging a hotspot lets you change the forecast period. The orange line then shortens or
lengthens to show the estimated failure counts.
