AB testing involves testing two different designs with two sets of users (usually five each). This is best used when you want to make sure your new design is better than the existing design (aka the “control”). Be careful not to do AB testing too early in the process, as you could just end up climbing a local maxima.
…at developers are able to get farther with front-end design without having to wait for design help. Rather than talking about what we can’t do when asking for headcount, I focus on showing all the great work we are already doing, and then paint a picture of what else we could do with more people.
