Role-based access control (RBAC) has to scale across tenants, brands, and locations—without creating a policy maze.
Scoping model
- Tenant scope: The organization (brand or company).
- Location scope: One or more stores within a tenant.
- Resource scope: Specific domains (sales, inventory, labor, finance).
Roles and permissions
- Global Admin: Manage tenants, billing, and compliance.
- Ops Manager: Multi-location oversight; approve reconciliations and anomalies.
- Location Manager: Day-to-day tasks, corrections, staff updates.
- Analyst: Read-only with export privileges.
Evaluation strategy
- Early deny for missing tenant or location membership.
- Policy evaluation per resource action with clear reasons (for audit).
- Decision logs including who, what, where, when, and why.
UX considerations
- Surface why an action is disabled and who can grant it.
- Provide a request-access workflow with approvers and SLAs.
- Keep the nav contextual to the current location to reduce errors.
Performance and safety
- Cache role grants per session with scoped invalidation.
- Enforce row-level filters in queries for tenant/location.
- Run a permission matrix test suite in CI for critical paths.
This approach keeps access safe, auditable, and understandable as the operation grows.
