RPN enables a calculated field for computing and storing RPN on your work items.
All defects are created equal.
RPN [RPN (Risk Priority Number)] is a calculation of several factors in a defect to help quantify the overall risk of a defect.
Four values are used to calculate RPN (for our use here):
- Severity
- Occurence
- Detection
- Users Affected
- The first thing you need is to create the fields that will store the RPN value. Create a custom decimal field through the process hub and add it to the work items you want to display RPN data on.
NOTE These fields typically are integer or picklist-integer(Example: "1,2,3,4,5,6,7,8,9,10"). However, in specific cases you can make these a string/picklist-string. In the case of using 'picklist-string', the format needs to be
<number> - description of number.
Example:
1 - low probability
2 - medium probability
10 - extra high probability
100 - super mega-high chance of occurence
- Navigate to the "RPN" hub on the collection settings admin experience. From here, you must specify the fields that will be used for Severity, Occurence, Detection, Users Affected, and RPN.
- RPN truncates Severity, Occurence, Detection, Users Affected to just be a number.
- RPN is automatically updated when form is loaded.
- RPN is automatically updated when any input field is updated.
- Update RPN for all selected work items on the backlog or query grid.
- Specify which fields are used for Severity, Occurence, Detection, Users Affected, and RPN.
Because this extension requires the new work item form, it is only supported on Azure DevOps and the next version of TFS 2018 and above.
