RE: Agile Estimation & Team Velocity

Here is an example of Agile Estimation & Team Velocity:

 

Assumption:

 

Resource Count: 8

Sprint - 4 Weeks (20 Days)

Team Velocity: 2000 Points

Per Sprint Per Resource Velocity: 250 Points

Productive Hours (Per Day): 6.5 Hrs

 

Story Sizes:

	Story Points	Days	Range (In Days)
Low	10	0.5	0.5-1 Day
Low-Medium	20	1.5	1-2 Days
Medium	30	2.5	2-3 Days
High	50	4.5	4-5 Days

 

 

Resource	Sprint Duration (4 weeks)	Velocity (Points)	Per Resource (Points) In 4 Weeks Sprint
8	20	2000	250

 

Below demonstrate kind of proper distribution of stories based on their point based estimate and days based estimate totaling to 2000 Points and 20 Days.

Well there is not necessarily directly proportional relation between story points and days.

 

However I tried demonstrating the same to justify Point Based & Days Based Estimation equally.

 

Estimate (In Days)	4.5	2.5	1.5	0.5	Days	Points (Per Resource)	Hours (6.5)
Estimate (In Points)	50	30	20	10
Resource 1	2	2	2	5	20	250	127
Resource 2	3	1	1	5	20	250	130
Resource 3	3	1	1	5	20	250	130
Resource 4	3	1	1	5	20	250	130
Resource 5	3	1	1	5	20	250	130
Resource 6	3	1	1	5	20	250	130
Resource 7	3	1	1	5	20	250	130
Resource 8	3	1	1	5	20	250	130
Total Stories	23	9	9	40	81	2000	1037
Total Points	1150	270	180	400	2000

 

 

Hope this helps.
