Software development is all about accurately capturing what the user wants. More accuracy is always better, of course. But what if you could have more accuracy while also saving costs? Why wouldn’t you want that?
Traditional software development was to actually write the software, get your users to test it, have their inevitable change requests come in, change your software, test again, etc. It’s more labor intensive that way (thus more costly), but more importantly it’s less accurate, though that might seem counterintuitive. When you deliver something the user does not want, you did not accurately give them their desired solution. By accurately capturing what the user wants earlier in the process, developers can more accurately engineer the solution later.
For example, let’s say you are mocking up new screens in wireframes on Figma. It’s much easier to change a wireframe than to change code, and for the user it’s basically the same thing. They see the UI changes, get to make their change requests, and you get to implement those change requests in Figma, not in code.
But usability testing takes this a step further. By using mood boards you can get on the same page as your user early in the dev process. Using rapid prototyping lets you quickly iterate through various ideas in the early, cheaper stages of the project. And then wireframing, whether you are using Figma, Sketch or XD files, lets your users see how the app will appear. All of this can be done during the early, cheaper stages, and why wouldn’t you take advantage of that with the great tools we now have? Usability testing gives you more accuracy at a lower cost. Can’t beat that!
