Hanyoyin ƙima
✓ BREAK DOWN → estimate small tasks; big things are always underestimated
✓ RELATIVE sizing → story points / t-shirt sizes (S/M/L) over false-precise hours
✓ Use HISTORY → what did similar work actually take? (velocity)
✓ THREE-POINT → best / likely / worst case to capture uncertainty
✓ Involve the people DOING the work — not just the lead
