  1. Hypothesis Driven Design @tsmz We’ve seen… We think this is

    because… So if we… We’ll see... ahem!

  6. Hypothesis Driven Design @tsmz Affinity sort What did we see?

    Anything ready to build? Everything else, back to start.
  7. Hypothesis Driven Design @tsmz Title User needs Hypothesis Link to

    prototype pages Screengrabs & photos Research methods & findings Link to JIRA ticket(s) telling the story
  8. Hypothesis Driven Design @tsmz A complete picture How were design

    decisions made? What research was done? What was the outcome?
  9. Hypothesis Driven Design @tsmz Audit trail Does the final build

    match the intention? How did the product end up like this? Useful for new starters / stakeholders alike.
  10. Hypothesis Driven Design @tsmz Problem Not all users understand what

    the most State Pension they could get is. This results in enquires to the digital service and contact centre.
  11. Hypothesis Driven Design @tsmz Hypothesis If messages are personal and

    direct, users will understand if they can increase their pension as a result enquiries should reduce.
  12. Hypothesis Driven Design @tsmz Measured • Enquiries and comments submitted

    to service • Satisfaction rate and survey • Skype/screen shares with users • Telephone calls to operations
  13. Hypothesis Driven Design @tsmz Even though it increased drop-outs, there

    were more eligible claims received” – Richard Smith “
  14. Hypothesis Driven Design @tsmz Errors on initial travel question 3.95%

    Loops back to initial question from next page 2.6% Users changing their mind 12.9%
  15. Hypothesis Driven Design @tsmz We’ve seen: 15.4% of users either

    change the radio button they’ve selected or return to the page and change their answer and we’ve seen: validation errors increase on the initial help With Travel page from 0.24% to 3.95% We think this is because: users are struggling to understand the initial travel question and so they are; 1) changing their mind about what their answer should be 2) trying to continue without answering it 3) answering that they don't need help when they really do So if: We change the wording of the question, and add text to the 'yes' 'no' radio buttons to make it clearer Then we’ll see: the numbers of users changing their answer reduce, the number of users seeing validation errors (after travel) reduce.
  16. Hypothesis Driven Design @tsmz “There are too many saccades and

    no fixations at the beginning of the sentence - the eye is only drawn to ‘work OK’ leading to regressive reading and confusion” – Rebekah Barry
  17. Hypothesis Driven Design @tsmz Errors on initial travel question 3.95%

    → 3.01% Loops back to initial question from next page 2.6% → 1.6% Users changing their mind 12.9% → 7.82%
