how to create and customize new unit in rally

Question

By default in Rally as a unit for estimation for stories is POINT. I would like to change it to something else, for example to Man days. So in setup-> Work-spaces & Projects -> Workspace1 --edit

Change field value "Plan Estimate Units" from "point" to "MD" (Man day).

But,.. there is a question, how the system can know that MD it is 8 hours?

Answer 1

The simplest answer is that the system won't know that your unit represents 8 hours. The Rally help site describes plan estimates as:

The amount of effort estimated to complete a single user story. Plan estimates are represented by points, t-shirt sizes, or other systems. They do not correspond to task or man hours.

The system doesn't do any conversion of these estimates to or from time.
