Analyzing deviations

After you run a deviation detection definition, you are likely to see many deviations. To understand deviations more clearly, follow this process:

  1. View the deviations, starting with the most significant deviation in descending order of magnitude.
  2. In the Deviation Viewer, look closely at the other deviations that are highlighted in red. The other deviations that have higher magnitude values might be the reason for the given deviation. (By moving the cursor over a deviation, you can see the magnitude value and whether the expected value is higher or lower than the actual value.)
  3. Continue to look through the list of deviations in the main window and view each deviation in context by opening the Deviation Viewer. As you read through the list of deviations, the magnitude, or importance, of the deviations decreases. Therefore, the significance of the deviation in the Deviation Viewer is reduced.
