How to define value proposition
Translate user's pain into your value proposition
"Here's the feature."
That's a common misconception. People often think about the feature instead of the benefit. When you're building up the product, you have to be clear about what's the value or the benefit.
Benefits, not features.
Let's say we build WhatsApp. People will be confused if we list features like: upload images, secured messaging, and status updates. By showing the list of features, people don't get the underlying value of why they should use the product. The alternative? Communicate the benefit. Perhaps, we can say, "You can call your family member anywhere."
