General remarks and user feedback
General remarks and user feedback

  • Avoid feature creep:

    • Focus on the most important tasks and options

    • People want every feature in a product but use only .01% of it

    • Focus on activities and actions in the tool. Make the tool itself as invisible as possible

  • User feedback

    • Very positive

    • User base has grown enormously

      • Old version: +/- 3000 uploads over 3 years

      • New version: 2010: 6095 videos uploaded

        2011: 17492 videos uploaded

      • Over 450.000 videos were watched by students in the past 12 months

      • Over 2.400.000 video streams (including live sessions) were sent out
