This feature is available in Enterprise and Ultimate editions.
Because terminology (Scrum, XP, DDSM, SAFe, etc.) varies across the industry, you can configure Lifecycle to use the terms specific to your organization. This article explains how to customize (or localize) terms used for measure attributes (e.g., Estimate or Swag).
Where to Find Measure Labels
Measure labels are primarily found on detail pages and grid columns. Below is one example of measure labels shown on a grid.
To make changes on the Terminology page, your Admin Privileges role must be set to "System Administrator".
Select Admin > System Configuration > Configuration > Terminology.
For each term you want to change, click in the Label cell and type the new term.
