Frequently Asked Questions
Is AI estimation accurate enough to replace planning poker?
Not entirely — but it is an excellent starting point. Refront's AI provides baseline estimates from historical data, which the team then validates or adjusts. The combination is more accurate than either alone.
Story points or hours — which is better?
Story points for relative complexity, hours for client billing. Refront maps between both — teams estimate in story points while AI suggests hour equivalents for billing purposes.
How do you improve estimation accuracy over time?
Track actual time vs. estimates for every task (Refront does this automatically). Review estimation accuracy in retrospectives. Over time, both AI and human estimates improve from this feedback loop.
