Start with the workflow, not the feature list
Features change quickly. The underlying workflow usually changes more slowly. Model who performs the action, what state changes, what data is required and what happens next.
- Define the primary actor
- Map the state transitions
- Identify irreversible data decisions
Stabilize identity, permissions and data ownership
Authentication can be replaced. Ownership rules are harder to unwind once data exists. Decide early whether records belong to a user, team, organization or workspace.
- Keep authorization server-side
- Make ownership explicit
- Record important status changes
Keep the interface modular
A small design system and reusable page patterns make iteration cheaper. The point is not to build a huge component library; it is to prevent every new screen from becoming a one-off.
