Velocity - An Important of Velocity in Agile Methodology

What is Velocity in Agile?

Velocity is one of the key matrices used by the scrum team. The average number of story points completed by the scrum team in the past few sprints.

In other words, "How many story points a team contain in a single sprint".

The purpose of velocity is to forecast the product backlog timeline. It is not a productive matrix. Velocity should not be compared between teams.

How will you calculate the velocity in the initial phase of the agile project?

Velocity is the measure of the amount of work a team can tackle during a single sprint. It is calculated at the end of a sprint.

For Example,

Suppose every team member gives 8 story points per sprint for a 2-week sprint.

Total team member = 6

Holidays = 0

Story point = 8

Velocity = Total team member X Story point

????????????????? =? 6 X 8

??????????????? ??=? 48

Suppose Holiday = 1

Velocity = (Total team member X Story point) – Holiday

????????????????? =? (6 X 8) - 1

????????????????? =? 48 – 1

??????????????? = 47

Why should we track velocity?

To understand how long it will take for the scrum team to finish the entire product backlog item.

How to calculate velocity?

1. Calculate the total number of completed story points in the past 3 to 5 sprints.
2. Take the average of the story points.

For Example,

Suppose Story point for 3 sprints = 24,32,40

Average Story Point = Total number of story points/Number of sprints

?????????????????????????????????????????? =? 24+32+40/3

??????????????? ???????????????????????????=? 96/3

?????????????? ??????????????????????? = 32 -> Velocity of the team
