Prioritization is deciding what to do first when you can't do everything at once — which is always. As a starting point, two simple tools cover most situations: MoSCoW and the value vs. effort matrix.
MoSCoW
MUST have → without it, the release fails
SHOULD have → important, but not vital right now
COULD have → nice to have if there's time
WON'T have → explicitly out of scope (this time)
The power is in the column: naming what you're doing prevents scope creep and sets expectations.
