# Scenario planner
The Scenario Planner, a feature of the Deliverables report, helps you simulate and predict when your team will finish a project based on various inputs such as headcount, issue velocity, and scope.

## Key concepts


| **Variable** | **Description** |
|--------------|-----------------|
| Historical velocity | This is how fast the team has worked in the past. For example, if 100 issues were completed in 10 days, the historical velocity is 10 issues per day.<br><br>This rate is based on the work completed from the start of the deliverable up to the most recently finished issue.<br><br>Additionally, we apply a minimum rate of 0.25 issues/points per day. |
| Contributor ratio | This considers how headcount will change. For example, if the team grows from 5 to 8 people, the team's capacity increases by a factor of 1.6 (because 8 ÷ 5 = 1.6). |
| Attention ratio | This considers how attention will change. For example, if time spent on the deliverable increases from 50% to 100%, the team's capacity increases by a factor of 2 (because 100 ÷ 50 = 2). |
| Remaining scope | This is the amount of work left to do, measured in issues or points. |


## Calculations

**Projected Velocity**  
Historical Velocity (how fast the team worked in the past) x Contributor Ratio (how team size will change) x Attention Ratio (how attention will change). This yields how much scope will be completed per day going forward.

**Projected Completion**  
Remaining Scope divided by the Projected Velocity. This yields how many days from now the work will be finished.

**Remaining Time**  
How much time is left (in days) from now until the projected completion date.

**Remaining Effort**  
How many dev weeks 1 engineer at 100% capacity would need to finish the remaining work.

## Example

#### Scenario

- **Historical data:** 5 contributors completed 100 issues in 10 days at 50% attention.
- **Future changes**: 8 contributors will focus 100% of their attention on the deliverable.
- **Today's date:** Jan 1

#### Inputs

- **Contributors**: 8 (Contributor Ratio = 8/5 = 1.6)
- **Attention**: 100% (Attention Ratio = 100 / 50 = 2)
- **Remaining Scope**: 200 issues

#### Results

- **Historical Velocity**: 10 issues per day (100 issues ÷ 10 days)
- **Projected Velocity**: 10 × 1.6 × 2 = **32 issues/day**
- **Time to complete**: 200 (issues remaining) ÷ 32 = **6.25 days**
- **Projected completion**: Jan 1 + 7 days = **Jan 8**
