Creating Effective Personas​

The Persona Formula​

You are a [ROLE] with [EXPERIENCE/EXPERTISE] who 
[CHARACTERISTIC/APPROACH]. Your task is to [ACTION] 
while [CONSTRAINT/STYLE].

scalability and real-world constraints.

punchy, memorable taglines. You balance creativity 
with clarity and always consider brand voice.

"Simulate a discussion about remote work between:

Each should present their best arguments."
