Frequently Asked Questions

What are story points?
Story points are a unit of measure used in Agile to estimate the overall effort required to implement a product backlog item. They combine complexity, effort, and uncertainty rather than pure time estimates.
Why use Fibonacci numbers for story points?
Fibonacci numbers (1, 2, 3, 5, 8, 13, 21) are used because larger tasks have inherently more uncertainty. The increasing gaps between numbers reflect that it is harder to precisely estimate large items, encouraging teams to break them down.
