    GARAGE SYSTEM CASE STUDY

    Step 1: Problem Statement Analysis (Garage)

    Banner

    Core Product Features

    A commercial garage management platform must coordinate:

    1. Customer & Vehicle Log: Linking cars (VIN, plate, model) to their respective owners.
    2. Service Bookings: Scheduling repairs and maintenance check-ups.
    3. Job Allocation: Assigning repair tasks to qualified Mechanics.
    4. Inventory Control: Tracking stock levels of spare parts (filters, brake pads) used during repairs.
    5. Invoicing & Billing: Tallying up labor hours and part costs into a unified bill.

    ️ Key Technical Challenges

    • Multi-Part Service Orders: A single booking can require multiple distinct repairs (e.g. oil change + tire rotation), needing proper junction mapping.
    • Inventory Depletion Tracking: Preventing race conditions when multiple mechanics checkout the same spare part simultaneously.

    Business Rules

    • A mechanic cannot be assigned to overlapping service bookings.
    • Parts cannot be checked out for a job if their inventory quantity reaches zero.
