High risk work refers to all the branches that contain high level of code changes and high level of rework or refactor.
The risk level of a branch is affected by the total code changes introduced in this branch and the changes that are done to existing code. More code changes and more changes in existing code increase the level of the risk.
You should check out the high risk work during the iteration in order to see which branches needs your attention as a manager, needs more review and more testing.
High Risk is a predefined compound filter that shows all the branches with:
State - Active - Branches that were updated within the last 7 days.
New Work - Small (<50%) - Ratio of the new work from entire work is below 50%.
Changes - Large( >300) - The total code changes exceeds 300 lines.
