How Many Test Users? 3… 5… 10? Try 46!

Quick win

Yes, this is yet another blog post on number of test participants, but this time it is based on very large samples and statistical wizardry. The total length of remote user research videos recorded by the WhatUsersDo platform in 2014 adds up to a jaw-dropping 2861 hours 03 minutes and 43 seconds. (It would take 120 days to watch them, if you would be watching user videos 24/7 without a break.) The core research for this article is based on 375 videos. After statistically analysing those results, I must say that 5 users is way too low. Most of the time you end up finding about 31% or less of all possible insights. How do I know what is the number of all possible insights? Because we conducted a very large-scale study, and found no unique insights, everything was repeated at least twice.

He did a few things that would make a mass murderer shiver.

UX Kanban Style

Quick win

I will demonstrate to you how a methodology developed by a Japanese car manufacturer in the ‘50s can tremendously improve the workflow of the team you are managing, especially a creative team. After implementing Kanban at WhatUsersDo, we now have a streamlined workflow, which now can be overviewed and managed easily. We can see bottlenecks and pain-points at a glance, but most importantly everything works smoothly and in a transparent manner, reducing frustration and stress for the team members.

Why cross-training is vital in UX?

Quick win

Start cross-training the employees in your UX team as soon as possible. The cheapest and most effective cross-training is when members of the same organization train each other. This creates a broader understanding of the organization, but benefits do not stop there…
