An MVP is the smallest version that lets real users complete the core job. It is not a rough draft of every screen you might want later. If nobody can name the job, you do not have an MVP. You have a feature list.
A fuller product is what you build after that use is visible: more roles, more edge cases, and the operational tools the team needs. Skipping the learning release usually means building the edge cases first.
Sovassa scopes the first slice so the next decision can be made from use, not from a longer workshop.
