You can estimate the value of efforts meaningfully in the form of units using the TeamForge tracker.
You can set any unit as the default for a tracker or planning folder and create any number of units. The default base unit is 'Hours' which you can rename, but not delete. You can also toggle between the burndown chart and effort values for any unit.
- Click Project Admin in the project navigation bar.
- Click Tracker Settings.
- On the Units Layout tab, click Add Field.
- On the Add Unit page, enter the Unit Name and Conversion value for the unit.
