PRD Template for User Roles
A complete product requirements template for building role-based access control. Pre-filled with examples for permissions, admin panels, invite flows, and enterprise access policies.
What makes user roles PRDs different
Access control is the foundation of multi-user products. Unlike most features that add value, RBAC primarily prevents harm — unauthorized deletions, data leaks, and compliance violations. This makes it hard to justify in a product roadmap based on engagement metrics, but the cost of not having it becomes apparent in the first security incident or lost enterprise deal.
The biggest challenge in specifying RBAC is finding the right level of granularity. Too few permissions and the system is inflexible — users cannot do their jobs without being given more access than they need. Too many permissions and the admin experience becomes a nightmare — a matrix of 50 checkboxes that nobody understands. The sweet spot is 15-25 granular permissions grouped into 3-4 predefined roles, with the option for custom roles as an advanced feature.
The template below provides a pragmatic RBAC specification that works for most SaaS products, from early-stage teams adding their first roles to growth-stage companies meeting enterprise compliance requirements.
User Roles PRD template
Eight sections covering every aspect of role-based access control.
Problem Statement
As products grow beyond individual users to teams and organizations, access control becomes essential. Without proper roles and permissions, either everyone can do everything (risky) or access requests create a bottleneck that slows down the entire team.
Example: "All users in our product have the same access level — every team member can delete projects, invite users, change billing, and access all data. This caused two incidents in the last quarter: an intern accidentally deleted a production project, and a contractor accessed billing information they should not have seen. Our largest enterprise prospect (a $120K/year deal) requires role-based access control with admin, editor, and viewer roles as a security prerequisite for deployment."
Tips
- Document security incidents caused by insufficient access control
- List enterprise deals that require RBAC as a prerequisite
- Identify actions that should be restricted to specific roles
- Survey team leads to understand their ideal permission model
Goals and Objectives
User roles goals must balance security (restricting what people can do) with usability (not blocking legitimate work). Overly restrictive permissions create friction; overly permissive ones create risk.
Example: "Primary: Implement role-based access control with admin, editor, and viewer roles that eliminate unauthorized access to destructive actions. Security: Zero unauthorized access incidents per quarter. Usability: Role assignment takes under 30 seconds and does not require contacting support. Enterprise: Meet SOC2 access control requirements. Self-service: Admins can create custom roles with granular permissions."
Tips
- Define 3-4 built-in roles that cover 90% of use cases
- Set a zero-incidents target for unauthorized access
- Include an admin self-service goal — role management should not require engineering
- Specify compliance requirements (SOC2, GDPR data access controls) upfront
User Stories
User roles stories span admins (who manage access), members (who work within their permissions), and the system itself (which enforces access control transparently). Include both the management experience and the enforcement experience.
Example: "As an organization admin, I want to assign roles to team members so that each person has access appropriate to their responsibility. Acceptance criteria: admin can assign admin, editor, or viewer roles to any member; role changes take effect immediately; the member sees an updated UI reflecting their new permissions; audit log records who changed which role and when."
Tips
- Write stories for role assignment, role change, and role revocation
- Include a story for what happens when a user attempts an unauthorized action
- Cover custom roles: "As an admin, I want to create a custom role with specific permissions"
- Add a story for workspace-level role overrides (different role in different workspaces)
Functional Requirements
Role and permission requirements must define the role hierarchy, permission granularity, enforcement points, and administrative interfaces. The permission model you choose (RBAC, ABAC, or a hybrid) affects the entire application.
Example: "FR-1: The system must support three built-in roles: admin (full access), editor (create and edit, no delete or billing), viewer (read-only). FR-2: Admins must be able to create custom roles by selecting from a permission matrix. FR-3: Permissions must be enforced at the API level — unauthorized requests return 403 Forbidden. FR-4: The UI must hide or disable actions the user does not have permission to perform. FR-5: Role changes must take effect within 5 seconds without requiring the user to log out and back in."
Tips
- Define the complete permission matrix: which roles can perform which actions on which resources
- Specify enforcement at both the API level (authoritative) and UI level (cosmetic)
- Include requirements for permission inheritance: org role vs. workspace role override
- Define the behavior when a permission check fails (error message, redirect, disabled button)
Non-Functional Requirements
Permission checks happen on every request, so they must be fast. They must also be consistent — a user should never see data they do not have access to, even briefly. Audit logging for all access control changes is typically a compliance requirement.
Example: "NFR-1: Permission checks must add no more than 5ms to request latency. NFR-2: Permission changes must propagate across all active sessions within 5 seconds. NFR-3: All role assignments, changes, and revocations must be recorded in an immutable audit log. NFR-4: The permission system must support at least 50 distinct permissions without performance degradation. NFR-5: Resource-level access checks (can this user access this specific project?) must complete within 10ms."
Tips
- Set latency budgets for permission checks — they happen on every request
- Require real-time propagation of permission changes (no stale sessions)
- Include audit logging requirements for all access control operations
- Specify the scale: maximum number of roles, permissions, and users the system must support
Success Metrics
User roles success is measured by security improvement (fewer incidents), admin efficiency (faster role management), and user experience (permissions do not block legitimate work).
Example: "Metric 1: Unauthorized access incidents. Baseline: 2/quarter. Target: 0. Metric 2: Time to assign a role to a new team member. Target: under 30 seconds. Metric 3: Permission-related support tickets. Target: under 5/month. Metric 4: Enterprise deals unblocked by RBAC. Target: close 3+ deals that required RBAC within 6 months. Metric 5: False positive rate (legitimate actions incorrectly blocked). Target: 0."
Tips
- Track unauthorized access incidents as the primary security metric
- Measure time to manage roles as a usability metric
- Monitor false positives — legitimate users being blocked by incorrect permissions
- Track enterprise deals that list RBAC as a buying criterion
Technical Considerations
Permission architecture must be designed for performance (checked on every request), consistency (no stale permissions), and extensibility (new permissions as new features are added). The choice between RBAC, ABAC, and hybrid models affects the entire authorization layer.
Example: "We will implement role-based access control (RBAC) with a permission matrix stored in the database. Roles are defined at the organization level with optional workspace-level overrides. Permission checks use a cached permission set per user session, refreshed every 60 seconds and on any role change event. The permission format is 'resource:action' (e.g., 'projects:delete', 'billing:manage'). API routes enforce permissions via a middleware that calls assertPermission(request.tenant, 'resource:action')."
Tips
- Use RBAC for most products — it covers 95% of access control needs
- Cache permission sets per session to avoid database lookups on every request
- Design the permission format as 'resource:action' for clarity and extensibility
- Plan for workspace-level role overrides from the start — retrofitting is painful
Risks and Mitigations
User roles risks include permission escalation (users gaining unauthorized access), migration issues (breaking existing users when introducing roles), and over-restriction (permissions that are too granular, creating admin burden).
Example: "Risk: Introducing roles breaks existing users who currently have full access. Likelihood: High. Impact: High. Mitigation: All existing users are initially assigned the admin role, preserving their current access. Admins can then adjust roles as needed. Risk: A bug in permission checking allows unauthorized access to sensitive data. Likelihood: Medium. Impact: Critical. Mitigation: Permission enforcement at the API layer (not just UI). Automated security tests that verify unauthorized users receive 403 for every protected endpoint."
Tips
- Plan the migration path: how existing users are assigned roles when RBAC is introduced
- Test for permission escalation: verify users cannot access resources above their role
- Keep the default role set simple (3-4 roles) to avoid admin burden
- Include automated tests for every protected endpoint to prevent permission bypasses
