How to Support Institutionalization of a Mature UX Practice
How to Support Institutionalization of a Mature UX Practice – Culture change, industrial strength practices, and knowledge management
As I understand, this topic is based on Institutionalization of Usability: A Step-by-Step Guide by Eric Schaffer. It was hardest part for me. There were questions from marketing, organization management, medicine (e.g. medical devices for UX/usability testings) and other.
As a Certified User Experience Analyst, you noticed that your
organization's approach to screen design is still fairly ad hoc, and
the designers do not leverage reusable components. You determine it
