  • 3. value proposition... Every dollar invested in Usability returns $10 to $100 Realize: better business requirements shorter development cycles non-functional requirements - design *SWOT analysis * Strengths Weakness Opportunities Threats 3
  • 4. a few definitions... 4
  • 5. usability? • Effectiveness - can users achieve their goal • Ease of learning - how fast do they learn the interface • Efficiency of use - how fast users complete tasks • Memorability - short & long term memory leveraged • Error prevention - is there forgiveness • User satisfaction - do users like the application 5
  • 6. mental model? • “Things should work the way we think they should work...” • break the user’s mental model - they respond negatively • techniques to explore the user’s mental model include card sorting and 1:1 usability testing 6
  • 7. user centered design? User-centered design (UCD) is a structured product development methodology that involves users throughout all stages of the development lifecycle, in order to create a web site or application that meets users' needs. This approach considers an organization's business objectives and the user's needs, limitations, and preferences. 7
  • 8. the process... To create a user-centered web site you must think about the needs of your users throughout each step in the development of your site, including: plan (objectives & requirements) collect data from user population (observation) prototype (low-fidelity) test 1:1 with users (task based usability tests) 8

  • 18. the return... Increase Productivity Reduce Support Calls Reduce Training Conversion Rate Reduce Drop-off Reduce Learning Curve 18
