How to design better user experience
How do we measure our progress and success?
After rounds of discussion on budgeting and business goal settings, our team decided that we’d proceed with a qualitative user testing to improve user experience and achieve higher conversion rate.
Now the question that I need to answer as a UX designer is not how to make better design, but more importantly, how do we measure if we made progress.
Success Criteria
Measuring progress of our own
How long does it take for a user to understand what we are offering?
Where are you better or worse?
To answer these questions, I decided to set up a benchmark that defines and calculates the success criteria. Here’s a snippet of it:
How many users would we need per tests to be considered as statistically significant?
Anywhere between 5-20 is a reasonable number, and it depends a lot on the complexity and importance of the test. Nelson Norman Group suggests that anymore than 5 users for a qualitative test is a waste of resource, however a minimum of 20 should is required for any quantitative research.
What will the priorities be for the tests?
Depends on the business value, user value of each tests, we can sort them with the consideration of technical difficulties in mind. Here’s a kano model from my perspective, but We can move these around for sure.
“Generally, to improve a design, insight is better than numbers.”

What to test
How much information is just right for the targeted user group? And who are the targeted users?
Hypothesis：
For younger age group (20-40), a clean, concise UI that made up with mainly icons are preferred, and result in more opt-ins.
