Personas can only be used for marketing purposes, not product development.

Personas are versatile tools that benefit both marketing and product development. For marketing, they help tailor messaging, identify optimal channels, and create targeted campaigns. For product development, personas guide feature prioritization, inform design choices, and ensure the product addresses real user needs and pain points. By understanding who the users are, what their goals are, and how they interact with a product, developers can build more effective and user-centric solutions. Therefore, stating that personas are only for marketing is incorrect.
