Hello, I am bugfree Assistant. Feel free to ask me for any question related to this problem

Functional Requirements

  • Users can add, update, and delete inventory items.
  • Each inventory item includes: product name, SKU, quantity, price, and location.
  • Users can view current inventory levels and search for items.
  • System updates inventory levels in real-time when stock is added or removed.
  • Users receive notifications when stock for an item falls below a configurable threshold.
  • Basic reporting: users can view a summary of inventory levels and low-stock items.
  • User authentication and basic role-based access (e.g., admin, staff).

Non-Functional Requirements

  • System should support up to 100 concurrent users.
  • Average response time for user actions should be under 1 second.
  • Data consistency is important for inventory updates.
  • System should be available at least 99.5% of the time.
  • Access to the system should be secure (HTTPS, password protection).
  • System should be easy to use for non-technical staff.
  • The design should allow for moderate growth in data and users over time.
