How it works

1

Map screens to roles, not roles to screens

Every screen explicitly lists which roles need it, avoiding the default assumption that all roles see all screens.

2

Attach actions per screen

Each screen carries its available actions, so permission design can be verified against actual listed capabilities rather than assumed from the screen name.

3

Flag roles with no screens or unused roles

Any defined role that appears in no screen's access list is flagged, since it likely means that role's experience has not been designed yet.

Frequently asked questions

What if a role can view but not edit a screen?

List the role under the screen, and note the view-only limitation in the actions field (e.g. "view invoices" without "update payment method") to distinguish read from write access.

How does this help with permission design specifically?

It gives you a single reference table of exactly who should see what, which PermissionUX or a developer can use directly to implement access control checks.

What if two roles need almost the same screens?

That is a useful signal — very similar roles may not need fully separate designs, and could share a screen with minor role-conditional differences instead.

Does this replace a full RBAC (role-based access control) system design?

No — this maps the UX/screen visibility per role. Pair it with PermissionUX and your backend's actual RBAC implementation for full access control.
