The next 45 minutes… • Travel@IU case study • Personas • Scenarios • The benefits • The challenges • For those about to ‘personafy’ • Questions & discussion
Traveling at Indiana University • 40,000 trips processed annually • 8 IU campuses • Travel authorization and reimbursement • Multiple user profiles and goals • Traditionally a paper process • Initial web-based system piloted and failed
Project goals • Improve the usability of the web application • Re-engineer process where necessary • Design leads development • Resources: • 1.5 FTE research & interaction designers • 1.5 FTE programmers • Timeline: • Design: May-November (50%) • Development: September-April (50%)
"An absolute travesty in taking a lousy process and technology-enabling it to make it worse" Document Analysis “Never encountered a form or web interface as unfriendly, overburdening to the user, and as time consuming as TAPSWEB…. Needs some serious end-user usability studies on this system”

About personas • Made popular by Alan Cooper • The Inmates are Running the Asylum (1999) • About Face 2.0 (2003) • Hot topic in recent years • Conferences, listserv discussions • Increasing number of case studies
What are personas? • Fictional, representative user archetypes • Based directly on data from user research • They include names, personalities, photos, backgrounds, contexts, and goals • Seldom a one-to-one correlation between personas and job description (often multiple personas in a single job)
Why personas? • Difficult to design for ‘everybody’ • 50% satisfaction for all usersOR…110% satisfaction for part of the population
Personas for Travel@IU • Seven personas • 4 primary • Staff traveler • Faculty traveler • Travel arranger • Travel approver • 3 secondary • Student traveler • Travel department staff • Fiscal officer
Scenarios • Specific to personas • 3-4 scenarios/persona • Common + edge cases
The value of personas • Improved team understanding of audience’s behaviors, contexts, and goals • Synthesize and confirm user research data • They avoid the ‘elastic user’ (Freydenson, 2002) • Augments other design activities (scenarios, testing) • Helps large teams where only a few members conduct the user research
What are some challenges? • Not enough just to know about them – must integrate with other practices (Blomquist 2002) • How much detail is enough? • Not an exact science, only best practices – your personas will look a little different than mine • Maintaining the momentum
For those about to ‘personafy’ • Base personas on your user research data! • Keep persona sets small • Add life to your personas but don’t go crazy • Focus on workflow, behavior patterns, end goals • Check your interpretations with your audience • Be willing to refine and iterate as you go • Guard against reusing personas – they should be specific to the design problem
