Setting the Table, Clearing the Table: The Challenge of Quant Personas
Personas can bring immense value to conversations about journeys and usage scenarios and deep understanding of your user groups. But can they be quantified? Personas are most effective when they combine qualitative and quantitative data to distinguish one individual from another individual or one group from another. That is, after all, what personas are largely about: the differences, or variances, between people.
How we think about quantitative personas at Akendi:
◦ Imagine rows of observations (or answers to a questionnaire) of different individuals. This string of numbers can be thought of as the 'location' of individuals in relation to each other. If two individuals share the same numbers in their observations, they are in the same 'location.'
◦ From this perspective, building quantitative personas essentially means finding specific 'locations' in this variable space that will be useful in business and design decision-making. Locations where many individuals are clustered around.
◦ To get there, striking the right balance in terms of relevant variables is important. Too many columns of data (variables), and you risk your data becoming too sparse. Conversely, too few columns may cause you to overlook important variables that distinguish individuals from one another.
◦ To strike the right balance, start with qualitative research (interviews, for instance) to guide you and quantitative approaches (like factor analysis) to identify the most useful variables. This improves the chances of your quantitative data finding meaningful differences between individuals.
◦ Finding the right balance and coming to the right interpretation of the qualitative and quantitative data requires not just math/stats, but insights and goals from the whole team; including, of course, business.
