One decisive workflow
The first release should answer one important question for one real user group. Broad feature lists consume the time needed to make that path dependable.
Access before activity
Technical access, data samples, owners and approval paths need to be available immediately. Waiting for a credential can erase the advantage of an urgent team.
Acceptance before polish
Define the evidence that makes the MVP useful: a completed workflow, an integration response, an evaluation threshold or a decision from a pilot user.
