Estimating story points
Story points express the relative size of a user story. Instead of guessing hours, you score three factors — complexity, uncertainty and effort — each on a scale of 1 to 5.
From score to Fibonacci
The calculator sums your three scores and maps the result to the nearest Fibonacci value (1, 2, 3, 5, 8, 13, 21). That's the scale most agile teams use during planning poker.
Tips
- Estimate together with the team — differences of opinion are valuable.
- Use a familiar story as an anchor.
- Is a story bigger than 13 points? Split it.
