“There have been some who have proclaimed the impending demise of personas as a UX design approach since shortly after their introduction. While the optimal approach to creating and employing personas is still evolving—thanks to more useful data becoming available to design teams and new project-management methods—their usefulness has not yet diminished. If anything, personas have become even more useful because they put a human face on aggregated data and foster a user-centered design approach even within the context of efficiency-driven development processes.”
