### How do you estimate work effort?

- Man-days
- Story points

### Which hourly rate should we use?

- **Flat 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’s 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 on the [https://appfire.atlassian.net/wiki/spaces/BPEdc/pages/2534507202](https://appfire.atlassian.net/wiki/spaces/BPEdc/pages/2534507202)  page.

### Box hourly rate ($)

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

## Custom expenses

Custom expenses are one-time or recurring expenses that are not associated with specific work items. They can be beneficial for monitoring flexible or miscellaneous project-related expenditures.
