Before launching yourself in the creation of fancy personas, first ask yourself how you intend to use them. Will they act as a central repository of what you have learned about your users? Will you use them to educate your stakeholders on what a user actually need? Or will they be central to product strategy conversations aimed at defining the feature set of a Minimal Desirable Product? Answering this first question will help you decide what information to include with your persona and how you will present them to the intended audience. It will also help you measure, as objectively as possible, whether your personas are successful...or not.
