5. Data &
measurements
• Data:
• Story Points
• Sprint Timebox
• Hours per devs
• Basic measurements:
• Capacity
• Velocity

6. Capacity:
• ideal_hours * sprint_timebox * devs_of_
team
• Ex: 7.5 hs * 10 days * 5 devs = 375 hs
Monday, October 21, 13

7. Real capacity:
• Capacity - (Holidays - study days - breaks
or interruption - others)
• Ex: 375 hs - (1 dev * 3 days) = 352,5 hs

8. Velocity of sprint:
• (total_accepted_story_points / capacity)
real_capacity
• Ex: (36 / 375) 352,5 = 33,84 story points

10. Team Velocity:
• Velocity average of the last five sprints:
• Ex: (25 + 33 + 28 + 30 + 36) / 5 = 30,4

11. Indicators
