 |
| Scrum does not prescribe specific estimation&nbsp;techniques.&nbsp;
 |
| </p>
 |
| <p>
 |
| Estimation by analogy is one&nbsp;technique used by Scrum teams.&nbsp; The mechanism is very simple and consists of
 |
| comparing backlog items to similar backlog&nbsp;items that were previously implemented.&nbsp; Lack of
 |
| available&nbsp;data points will&nbsp;limit the effectiveness of this technique.&nbsp;
 |
| </p>
 |

 |
| Planning Poker is a popular iterative approach to estimating.&nbsp; Here are the steps:
 |
| </p>
 |
| <ul>
 |
| <li>
 |
| Each estimator is given a deck of cards, each card has a valid estimate written on it
 |
| </li>
 |
| <li>
 |
| The Product owner reads a story and it’s discussed briefly
 |
| </li>
 |
| <li>
 |
| Each estimator selects a card representing&nbsp;his or her estimate
 |
| </li>
 |
| <li>
 |
| The cards are turned over so all can see them
 |
| </li>
 |
| <li>
 |
| Discuss differences (especially outliers)
 |
| </li>
 |
| <li>
 |
| Re-estimate until estimates converge
 |
| </li>
 |
| </ul><br />
