How it works
Calculate a weighted index
Complexity and uncertainty each carry 30%; dependencies and testing 20%.
Map to Fibonacci
The index maps to 1, 2, 3, 5, 8 or 13 relative points.

Frequently asked questions
Are points hours?
No. They compare relative effort within one team and backlog.
Can teams compare points?
Not reliably; each team calibrates against its own reference work.
Why use Fibonacci?
Wider gaps reflect growing uncertainty in larger items.
What if the result is 13?
Treat it as a prompt to split the item or reduce unknowns before commitment.
