## The planning onion

## Release and sprint planning

## What is a good plan?

## Velocity


- A useful long-term measure of the amount of work completed per iteration
- Most useful over at least a handful of iterations

## Five planning scenarios
### A team with historical data
#### Calculate a confidence interval form historical data

#### Extrapolate from the velocity range

### Fixed-date plans
#### Fixed-date planning

#### Count the sprints

#### Determine a velocity range


#### Determine what to commit to

#### Balacing risk

### Fixed-scope plans
#### Fixed-scope planning



#### Ranges
- Notice in both cases we had a range
- For a **fixed-date project**, use a scope range:
- “By that date you will have all of these features and some of these.”
- For a **fixed-scope project**, use a date range:
- “It will take use between 6 and 8 sprints to deliver all those features.”

#### Past velocities


### A team with no velocity data
#### Forecast an initial velocity
* Get the team together as though there were going to plan a real sprint (2–4 weeks)
* Sprint planning involves
* Breaking product backlog items (features) into tasks
* Estimating the hours for each task
* Repeating until the sprint feels full
* See how many points are represented by the work they selected
* Consider planning a second iteration in this way

#### Consider this team

#### Establishing their velocity

#### Turn the point estimaste into a range
* If you do not have historical data
* Take a wild guess, perhaps:
* +/- 10% for a known team working together in a known application domain with known technologies
* +/- 50% if all that is unknown
* If you have historical data from other teams
* Calculate the relative standard deviation of those teams

#### Using data from other teams


### A team changing size
#### Track velocity when size changes

#### Impact of going from 6 to 7 people
