An introduction to usability and User-Centred Design for Information Professionals Sarah Agarwal Consultant Project Manager Internet Development group (ID)
What I’m going to cover: • what is User-Centred Design / usability? • what is its proven value? • how can Information Professional build user-centred activities into their projects / services? What I won’t be covering: • info about techniques
What is poor usability? “I really like it, but I don’t use it much” “It doesn’t do what I need it to do” To end-users.. “I can’t find what I’m looking for” “Can’t it be more like Google?” “I don’t think it seems trustworthy” “I find it a bit frustrating” “It’s very fancy, but it’s not very useful”
Value of User-Centred Design? Web managers view of user involvement • I haven’t really thought about it • I know what my users need • It would be nice to do more work with users but I don’t have the time/budget • My managers are happy with my stats, so that’s ‘job done’ • Customers are central to my service
Value of User-Centred Design? The Standish CHAOS report (1994): Red = success Green = completed, over-budget/time, under-functional Yellow = cancelled
Value of User-Centred Design? The Standish report (1994): Quarter of all projects: • cost overrun by 50-100% • time overrun of 100-200%
Value of User-Centred Design? The Standish report (1994): Project Success Factors % of Responses 1. User Involvement 15.9% 2. Executive Management Support 13.9% 3. Clear Statement of Requirements 13.0% 4. Proper Planning 9.6% 5. Realistic Expectations 8.2% 6. Smaller Project Milestones 7.7% Etc.
Trust The Web Credibility Research Project Stanford University - http://www.webcredibility.org/ Findings: • 46% of people base credibility judgements on “overall visual design of a site, including layout, typography, font size and color schemes” • Less than 10% referred to the identity of the site
Engendering trust 10 research-based guidelines from Stanford University, inc: • “Design your site so it looks professional (or is appropriate for your purpose). • Make your site easy to use -- and useful. • Avoid errors of all types, no matter how small they seem.”
Involving users in existing web services Some ‘dipping your toe in’ ideas: • Accost and ask users informally – free! • Ask consultants for some ideas about what user involvement would be useful for your site – free! • Heuristic review – cheap • Surveys – cheapish to average • User testing – average
Involving users in development projects Projects developed in-house: • Seek user involvement early • understand their requirements • graphic design development • information architecture and interaction design • technical environment • content type, format, level • Build-in time and budget for this (bearing CHAOS in mind!)
Involving users in development projects Partnership projects • Development methods • DSDM www.dsdm.org • User-Centred Design • Clients need to give time and effort, be involved and assist consultants in seeking user input. • Make planning the priority
