Imagine explaining how an app works to someone who’s not tech-savvy. Instead of writing a 10-page document, wouldn’t it be easier to just show them a diagram? That’s exactly what a Use Case Diagram does.
It’s a simple visual representation of how users interact with a system. It doesn’t show technical details—it’s more like a big-picture map that helps teams understand who’s using the system and what they’re doing with it.
Example:
Let’s say you’re designing an online shopping app. A Use Case Diagram might show:
🛒 “Customer” browsing products.
💳 “Customer” making a payment.
📦 “Warehouse staff” processing an order.
Why It’s Super Useful:
✅ Gives stakeholders a quick overview without technical jargon.
✅ Helps developers understand user needs before coding.
✅ Avoids miscommunication between business and tech teams.
Simple, clear, and to the point—exactly what you need in fast-moving projects!
