Ranking work items
You can rank work items to prioritize them according to your requirement or expected business value. Plans that are created with Rational® Team Concert® 4.0.5 or later use explicit ranking, where the rank can be edited independently of any other attribute. Plans that are created prior to Rational Team Concert 4.0.5 use attribute-based ranking, where the rank is related to the value of an attribute, such as priority.
About this task
If you have existing plans from releases prior to Rational Team Concert 4.0.5, you can migrate from attribute-based ranking to explicit ranking. Attribute-based ranking uses priority, severity, story points, or user-defined attributes as the primary sort attribute and rank as the secondary sort attribute. Explicit ranking uses rank to sort work items.
