When is it “Useable Enough?”

Notes from the UIE Brain Sparks podcast: Userability #9 - When is it "Useable Enough?"

  • Establish metrics for what is considered usable enough, e.g. 80% task completion, 90% satisfaction
  • Check out Measuring the User Experience
  • "Get to point of least astonishment", no more surprises during usability testing
  • Getting new results with each user, keep testing
  • Incomplete tasks - is the reason expected or a surprise
  • Tasks can be completed as expected = usable enough for beta release
  • Problem areas are not deemed large enough to hold off releasing in beta
  • Surprises after release, unexpected responses = didn't do enough work and testing (think anytime Facebook releases anything new or changed)
  • "Most people, most of the time"
