For any range defined in a forecast chart, Oracle Crystal Ball Enterprise Performance Management calculates the resulting certainty. The chance of any forecast value falling between –Infinity and +Infinity is always 100%. However, the chance (certainty) of that same forecast being at least zero (which you might want to calculate to make sure that you make a profit) might be only 45%. This way, not only do you know that your company has a chance to make a profit, but you can also quantify that chance by saying that the company has a 45% chance of making a profit on a venture (a venture you might, therefore, decide to skip).
To define certainty, perform one of the following actions in a forecast chart:
Enter a value in the Certainty field below the forecast chart
Enter a value in the fields on each side of the Certainty field below the forecast chart
Use certainty grabbers
In the forecast chart, move the certainty grabbers to focus on a particular part of the display area.
To anchor a certainty grabber, click it. To unanchor it, click it again.
To anchor or unanchor both certainty grabbers at once, use Ctrl+click.
If you unanchor both certainty grabbers and enter a certainty level, the grabbers move to define the appropriate certainty range.
To determine the certainty of values at the ends, move both certainty grabbers from one end to the other, crossing them.
Note:
The Certainty field and the minimum and maximum fields on each side of it are accessible with the Tab key.
