MoSCoW sorts scope into four buckets: Must have, Should have, Could have, and Won't have (this time). Its power for MVPs is the W — a written list of what you're deliberately not building is the strongest anti-scope-creep device that exists.
The method fails when everything lands in Must. Force ranking with hard questions.
Run MoSCoW against the validation goal, not against stakeholder enthusiasm: 'must have to learn X', not 'must have to look finished'. Revisit after each build-measure-learn loop.
Practical answers
If Musts exceed roughly 60% of the effort, the scope has no slack and the timeline is fiction. Cut until the Musts are genuinely minimal.
MoSCoW is fastest for scoping a first version. Scoring methods like RICE earn their overhead later, when there's real usage data to score with.
