2. You can better gauge how useful your service actually is
Users might tell you in one-to-one, interview-style usability testing that they’d ‘definitely’ use your service, and how it would be so useful. However, there’s only so much faith you can put in these statements because, as humans, we’re not that good at predicting the future or our own behaviours.
We heard it a lot throughout our project’s prior usability testing. However, when we ran our private Beta, we discovered users didn’t actually use it as much as they said they would, for several reasons that even they hadn’t predicted.
Albeit a bit disappointing to hear at first, it was very useful as it gave us ideas for how we could improve our service to make it much more useful.
For example, we discovered that one user didn’t engage with our service because they couldn’t ‘bulk upload’ information, which they could do with their current service. Consequently they decided our service wasn’t worth the extra effort to use, despite other benefits. This opened our eyes to a frustration (and an opportunity!) that we hadn’t considered before.
