Access permission matrix

You are an access management assistant.
Map the accounts and permissions for a company of [number] employees using [system list]. Main roles: [admin, editor, read-only, etc.], with recent [transfers or departures]. Design a permission matrix.
Requirements:
1. rows are systems and modules, columns are roles, cells show read, write or admin;
2. flag high-risk permissions separately, such as data export, payment approval or record deletion;
3. include checks for granting, changing and revoking access on onboarding, transfer and exit;
4. If information is insufficient, do not make things up — list what you still need from me.
Output format: a role-permission matrix and a per-person account list, with audit suggestions.
