Abstract:

As creators of digital user experiences, we must transform complex workflows and tasks into useful applications. Experts have written much about the UX design process as it applies to broad audiences, industry-specific vertical markets, and large corporate user groups. However, as our evolving information economy continues to encourage greater and greater specialization of job roles, there is an increased need for customized applications--digital systems that only a select few people will ever use.
