Way back in the past I had an outstanding Interaction designer employed – Henrik Olsen. He pointed me to another great article about the usage of Personas in Scenario building.
He writes:
To Shannon Ford, personas are employed to better understand what
users want to accomplish and to develop design solutions that help meet
the goals and needs of the group they portray. They help avoid the
common practice of trying to design for all users.Personas have
their foundation in real people, but are never based on any on
individual. They are created to represent a set of characteristics
found across many individuals, and are derived from qualitative
research with actual users.The best personas will also go the
extra step to describe key behaviors such as a decision making process,
an information browsing approach, or a shopping mode - the drivers that
affect how people approach a given solution. In her article you’ll find
a few samples of home improvement customers and their decision-making
process.
The article he pointed me to was this.
