Types of Personas
The design of all Fluid Components will be informed directly by the Primary & Secondary personas below. By definition, each primary persona requires their own user interface in a particular application. A secondary persona is one whose needs will be mostly served if the needs of the primary persona is met. There may be small additions to the interface necessary to meet the needs of a secondary persona, but these additions should not negatively affect the experience of the primary persona. (If this were the case, this secondary persona should be another primary persona and have their own interface.)
Auxiliary personas do represent models of users we saw in the field, but we don't believe are different enough from the primary and secondary personas that it is helpful to keep them in mind. However, we are making them available so that they can be used in a particular problem space as necessary. For example, Michael Demsky, the Departmental Support Person, is not that different from Anita Stalmach, who does Departmental Pedagogy Support. However, if there was a use case that involved this person doing a lot of section management, it may be more helpful to use Michael.
Additional personas may also be created based as additional user research is done (or as provisional personas if user research is not an option). This may prove necessary if we realize we don't have enough information on users in a particular problem space. For example, if we are working on a reorderer component in a context/problem space where reordering large collections of images is the primary use case, we may want to have a professor in a media-heavy discipline, such as Art History or Architecture, as a primary persona to inform our design & development process.
