The document discusses forecasting the total cost and duration to complete a product backlog using Scrum methodology. It is given that the team velocity is 30 points per sprint and each sprint is 2 weeks. It is calculated that it will take 5 sprints, or 10 weeks, to complete the backlog. With each sprint costing $30,000 in resources, the total cost to complete the backlog is estimated at $300,000. However, due to the uncertainty inherent in forecasts, the summary increases the estimates to 14 weeks duration and $360,000 cost.

1. Part 1:
Team velocity is 30 points*
Sprint length is two weeks**
How many Sprints will it take to complete Product Backlog?
Part 2:
What is the duration to complete?
Part 3:
What is the cost if a two week Sprint has a total resource rate of $30,000?

Forecasting Total Cost and Duration of Product Backlog
* If team velocity is not know you can extrapolate it by conducting a pseudo Sprint Planning session
**Team predetermines Sprint length –for the sake of this example I have select to use a two week Sprint

3. Part 1:
Team velocity is 30 points
Sprint length is two weeks
How many Sprints will it take to complete Product Backlog? Answer: 5 (based on Velocity of 30 points)
Part 2:
What is the duration to complete? Answer: 10 weeks (5 (Sprints) x 2 (weeks each Sprint) = 10)

4. Part 1:
Team velocity is 30 points
Sprint length is two weeks
How many Sprints will it take to complete Product Backlog? Answer: 5 (based on Velocity of 30 points)
Part 2:
What is the duration to complete? Answer: 10 weeks (5 (Sprints) x 2 (weeks each Sprint) = 10)
Part 3:
What is the total cost if a two week Sprint has a total resource rate of $30,000? Answer: $300,000 ( 10 Sprints x $30,000 = $300,000.00)

5. Forecasting Total Cost and Duration of Product Backlog
Copyright © 2014 Russell Pannone. All rights reserved.
Forecast based on calculations from previous slides =
•Duration to complete = 10 weeks
•Cost to complete = $300,000.00
Because of the relevance of the cone-of-uncertainty I would change forecast to:
Duration to complete = 14 weeks
Cost to complete = $360,000.00
