## What is agile planning?

#### Estimate size; derive duration

#### Measures of size

### Story points
* How long a user story will take (effort)
* Influenced by complexity, uncertainty, risk, volume of work, etc.
* Relative values are what is important:
    * A login screen is a 2.
    * A search feature is an 8.
* Basic math properties should hold
    * 5+5 = 10

### Ideal time
How long something will take if:
* it’s all you work on
* no one interrupts you
* and everything you need is available

#### Elapsed time versus ideal time

#### Two big advantages to story points
1. Story points are additive; time-based estimate may not be
2. Story points help avoid problems with unit confusion

#### Confusing units

## Estimating with Planning Poker
* An iterative approach to estimating
* Steps
    * Each estimator is given a deck of cards, each card has a valid estimate written on it
    * Customer/Product owner reads a story and it is discussed briefly
    * Each estimator selects a card that is his or her estimate
    * Cards are turned at the same time
    * Discuss differences (especially outliers)
    * Re-estimate until estimates converge
