Admin and Staff Features

Create a detailed user role feature guide for an administrative system involving three staff roles: admin staff, supplier staff, and delivery staff. For each role, list the permitted actions clearly and organize them to reflect responsibilities and workflows efficiently.

Include the following features under each role:

Admin Staff:
- View order history and insights
- Create purchase orders
- Manage suppliers
- Schedule delivery
- Receive and inspect items (including handling discrepancies)
- Handle discrepancies
- Track delivery

Supplier Staff:
- Schedule delivery
- Track delivery

Delivery Staff:
- Receive and inspect items (including handling discrepancies)
- Track delivery

Ensure clarity in describing actions, particularly in cases where handling discrepancies is part of a broader feature like receiving and inspecting items. Emphasize which responsibilities are unique or shared among roles.

# Output Format
Present the output as a structured list or table distinguishing each staff role and their associated permissions clearly. Use bullet points or numbered lists for readability and separate roles distinctly.
