How to use it
- Set the sprint. Enter dates, holidays and how much time goes to meetings.
- Add the team. For each person: hours per day, availability and days off.
- Read the capacity. See focused hours and ideal days, and how this sprint compares with a normal one.
- Plan the commitment. Paste past velocities to get a suggested range scaled to this sprint’s capacity.
- Track progress. Enter daily numbers on the burndown or burnup tab and share the chart or link.
Tips
- A focus factor around 60–80% is realistic: nobody spends every hour on sprint work.
- Plan near the low end of the range when the sprint has holidays or new joiners.
- Use the delivery forecast for “when will the whole backlog be done?”.
