Root Causes

Influence Analysis for Case Attributes shows correlations between cases selected in the Control Window and case attribute values in the model. For example, you might select cases that contain certain undesired event (in the flowchart) and analyze using the Influence Analysis for Case Attributes, which case attributes and their value have a connection to this undesired behavior. There might be causalities behind the correlations, which would then help to find root causes for the occurrence of the observed phenomenon.

In the Influence Analysis for Case Attributes one row represents cases with one case attribute value. The right-most colored column shows the correlation level between the selected cases and the case attribute value that the row represents.

Influence Analysis for Case Attributes is available in the Analysis Window only. The set of cases to find correlations, are selected in the Control Window. You can select for example:

• Cases that have a certain type of event (in the Flowchart Analysis)
• Cases that have a certain flow (transition between certain type of events) (in the Flowchart Analysis)
• Cases with certain case attribute values (in the Profiling Cases Analysis)
• Cases having certain range of durations, e.g. cases with the longest durations (in the Duration Analysis)
• Cases belonging to certain variations (in the Variation Analysis)

Shown Information - All Cases Have Equal Weight

When the Influence Analysis for Case Attributes doesn't operate in the Weighted by Case Value mode, each case has equal weight in the analysis.

When Show Detail Columns' in not activated, the following columns are shown:

• Case Attribute: Case attribute that the row represents.
• Attribute Value: Case attribute value that the row represents.
• Cases #: Number of cases having the case attribute value that the row represents.
• Selected %: Shows how many percentage of the cases with that case attribute value are in the selected set of cases. Calculation rule: [Selected #] / [Cases #] * 100.
• Contribution %: Percent of the selected cases with the attribute value that contributes to the "Difference %".

When Show Detail Columns is activated, the following additional columns are shown:

• Selected #: Number of cases in the selected group that have the case attribute value that the row represents.
• Compared #: Number or cases in the unselected group that have the case attribute value that the row represents. Calculation rule: [Cases #] - [Selected #].
• Difference %: Deviation in percentage between Selected % and the average percentage of selected cases among all analyzed cases.
• Contribution #: the number of cases which contribute to the "Difference %", i.e. the deviation from the average percentage. Shown when "Show Detail Columns" is selected in the analysis settings, but not when "Weighted by Case Value" is selected in the analysis settings.

Shown Information - Weighted by Case Value

When the Influence Analysis for Case Attributes works in the Weighted by Case Value mode, the weight of each case comes from the case attribute Cost. Then more important cases have greater weight in the analysis. Note that event attribute Cost is not taken into account by this analysis.

When Show Detail Columns' in not activated, the following columns are shown:

• Case Attribute: Case attribute that the row represents.
• Attribute Value: Case attribute value that the row represents.
• Cases Value: Sum of case costs of the cases having the case attribute value that the row represents.
• Selected %:
• Contribution %:

When Show Detail Columns is activated, the following additional columns are shown:

• Selected Value: Sum of case costs among the selected cases that have the case attribute value that the row represents.
• Compared Value: Sum of case costs among the unselected cases that have the case attribute value that the row represents. Calculation rule: [Cases Value] - [Selected Value].
• Contribution Value: the total cost of cases which contribute to the "Difference %".

When "Weighted by Case Value" is selected in the analysis settings, the percent of the cost of cases which contribute to the "Difference %"

shows the selected case attribute. You can select a particular case attribute or all case attributes from the Attribute drop-down menu in the Influence Analysis Settings. Note that only those attributes are shown in the list that are visible in the current filter. If you select the option <All>, all case attributes visible in the current filter are used in the analysis.

When "Weighted by Case Value" is selected in the analysis settings, the percent of selected case costs out of the total sum of case costs.

You can sort the columns in the analysis by clicking on the column headers. To filter the shown content of the table, click on the filter icon.

Analysis Settings

• Show: the number of top and bottom rows shown in the analysis.

All: all rows (max. 2000) are shown in the table.

Limit To: the value here is the limit to the number of shown top and bottom rows.

• Attribute: the case attribute to be shown on the analysis.
• Show Detail Columns: see the descriptions of the columns above for the effect of this setting.
• Weighted by Case Value: see the descriptions of the columns above for the effect of this setting. For this setting to work, the data needs to contain a case attribute named "Cost".
