# 6 Sprint Velocity

Sprint velocity calculations help the team to learn and continuously improve.

Sprint velocity = (work units completed / work units committed) during the sprint * 100

During the initial sprints, it is quite likely that teams can fail becuase they either over committed work or under committed. In the former case, at the end of the sprint, the team might not have completed the work committed at the start of the sprint. In the latter case, the sprint will get over before the sprint end date. After some learning through a couple of sprints, the team will learn to complete what they committed within the stipulated time frame. At that time, the sprint velocity calculation will show 100%.

# 5 Sprint Burn down chart

A sprint burn down chart helps to track the progress of work, and to make appropriate dec

isions as the sprint progresses. The 'Y' axis shows the 'effort' required to complete the balance work in tyhe sprint and the 'x' axis, the number of days of the sprint. The objective is to make the effort required to complete the sprint zero on or before the sprint end date.

In the conventional project management, we use the earned value management. The earned value chart focuses on the work completed so far. In the case of a burn down chart, the focus is on balance effort required to complete the pending activities.

Collabteam feature

Collabteam has the sprint burn down feature. The burn down is derived from the 'balance effort' against the tasks, which the team members updates regularly.
