What are Story Points?
Story points provide a way to discuss level of effort required to implement a change to a code base in a way that is more flexible than hour estimates. In one sentence:
Story points are a unit of measure for expressing an estimate of the overall effort that will be required to fully implement a product backlog item or any other piece of work.
(Taken from this article)
The following factors go into estimating story points:
- Amount of Work
- Complexity
- Risk or Uncertainty
Below is chart of story points along with a brief explanation of their meaning.
| Story Points | Explanation |
|---|---|
| 0.5 | A straight-forward part of a task |
| 1 | Part of a task |
| 2 | A small task |
| 3 | A medium task |
| 5 | A large task |
| 8 | A subset of a feature |
| 13 | An entire feature |
| 20 | Adding new functionality |
Effort estimation doesn’t get more granular than this level of detail since any more detail would lose flexibility.
