The following example, for illustration purposes, is for a fictitious business requesting a solution
Project Overview
We distribute fresh ingredients, and running out of key items (like certain oils or spices) can halt our clients' kitchens. We currently rely on manual, end-of-day checks, which are often too late.
Goal
Our goal is to receive real-time alerts whenever a critical inventory threshold is breached, allowing us to re-order instantly and avoid stock-outs. The system must be fast, accurate, and capable of sending alerts via both SMS and email, as managers aren't always at their computer. The core system needs to be easy for warehouse staff to update inventory numbers as items are used.
Topics & Scope
- The system needs a secure database to hold a list of all critical items, their current Stock Level, and the manager-defined Minimum Threshold for each item.
- Warehouse staff need a simple mobile/tablet-friendly Web Interface to quickly update the stock level for an item when a shipment arrives or leaves.
- Managers must have an admin portal to set and adjust the Minimum Threshold for any critical item.
- The core logic must run whenever an inventory number is updated.
- If the Current Stock Level is less than the Minimum Threshold, the system must trigger an alert.
- The system must track which items have already triggered an alert, and only send one alert per item until the stock level is replenished above the threshold (to prevent spam).
- Alerts must be sent simultaneously via both SMS (for immediate, urgent notification) and Email (for a detailed record).
- The alert message must clearly state the Item Name and the Current Low Stock Level.
- The manager needs an admin portal to designate which staff members receive SMS alerts and which receive email alerts.
