Reason

The Reason Tree tab is used to define the various reasons that can be assigned to alarm events. The pre-configured, hierarchical structure enables consistent reporting and root-cause analysis.

Reason: Name of reason branch.

Assign: Checking this allows a reason to be assigned. Branches that are only used as roots for other branches and are not reasons themselves should not have Assign checked off.

Inherit: The branch will inherit categories from upper branches. This minimizes the effort when multiple branches will use the same categories in their children branches. Categories are used to the filter the reason tree.

Full Reason: The Full Reason will automatically be built from the tree.

Active: Toggles the visibility of the reason and all branches of the reason in PARCview.

Reason Evidence

Reasons can be associated with evidence such that when a given reason is assigned to an event, the associated evidence will also be applied to the event. See the Evidence tab for how to set up evidence.

Evidence: Select the evidence class to associate with the selected reason.

Required: If checked, users must select an evidence value before the event meets the All Evidence Entered acknowledgment requirement.

Reason Category

Reasons can be grouped by category. Categories are used to filter the reason tree and in Pareto charts.

Category: Select the category or categories to which the selected reason will belong.

Reason Tree Right-Click Menu

Configure the reason tree using the right-click menu.

Add: Adds a reason branch below a reason.

Add Root: Adds a reason at the highest level.

Rename: To rename a reason, double-click on the reason and enter a new name.

Delete: Opens the Delete Reason window.

Replace: Replace reason with selected reason before deletion.

Unassign: Unassign reason from events before deletion.

Copy: Copies the reason and all its branches to be moved in the reason tree.

Paste: Pastes copied reasons as branches under the selected reason.

Share/Unshare: For causes that are applicable in multiple process areas, sharing a reason will cause them to be grouped together in reports. Unsharing will separate reasons on the report.
