Zadana vrijednost u Scrumu je zaštita Sprintnog cilja: nikakve promjene ne bi trebale biti dodane koje ga ugrožavaju. Ali Scrum nije krut — opseg se može ponovno pregovarati s Product Ownerom, i stvarno hitna promjena može biti obrađena, s eksplicitnim trade-offs.
Okvir za odlučivanje
1. Does the new request threaten the Sprint Goal?
NO → can it wait for the next Sprint? Usually yes → backlog it.
YES → talk to the Product Owner about trade-offs.
2. Is it a genuine emergency (prod down, legal, security)?
YES → the PO may cancel/replace work; something must drop.
3. Make the trade-off visible: pulling X in means Y comes out.
