UI modernisation research

Skills

Quantitative research, Usability evaluation, Synthesis.

Background

  • A new design (mainly focused on visual uplift had been created
  • Given large scale usage of product, needed to prove that interface changes improved task completion/usability.

Challenge

  • It was the first quant research undertaken by the chapter and there was a feeling that it would only slow things down.
  • A quant approach was important – to prove the new design would give improvements or at least not make things worse.
  • Wanted to test the visual design in a quantifiable way – not an easy thing to do

Actions

  • I created a shared research plan within the tribe to make sure the research was aligned with stakeholder/business needs.
  • I set up, ran and reported on the quantitative research using Userzoom to over 200 bank customers.

Whiteboard test plan

Study details:

  • 2 main customer segments
  • Probing questions on channel – web vs app – selection.
  • Random A/B split with series of 1st click testing on existing and planned UI designs with SEQ (Single Ease Question)and follow up questions for lower SEQ scores.
  • Product reaction analysis.

Results

  • Study showed although most tasks performed significantly better or the same, one key task was statistically worse in the new design due to button placement change.
  • New visual design accepted by business subject to changes driven by the research.

Lessons learned

Using a whiteboard test plan is a good way to allow for multiple edits and to share the plan outside the team

When using Userzoom – or any online tool – it’s important to have the study plan/questions completed before building the study.
