Why personas are important?
Personas are vital to the success of a product because they drive design decisions by taking common user needs and bringing them to the forefront of planning before design has actually started. Personas provide the team with a shared understanding of users in terms of goals and capabilities.
How do you write a user persona?
A user persona is a semi-fictional character based on your current (or ideal) customer. Personas can be created by talking to users and segmenting by various demographic and psychographic data to improve your product marketing.
