#### How do you estimate work effort?

- Man-days
- Story points

#### Which hourly rate should we use?

- **Box hourly rate** - use a single hourly rate for all tasks if the tasks are not assigned to teams
- **Team hourly rate** - use the team hourly rate if the tasks are assigned to teams and each team needs a different rate. If the team hourly rate is chosen and a team has not been set, the app sets $100 for the calculations. You can define hourly rates for teams in [the Administration configuration](https://appfire.atlassian.net/wiki/spaces/SPM/pages/1639554184).

#### Box hourly rate ($)

Set an hourly rate for the current box (initiative).
