There are some problems we don’t know we have.
Often referred to as ‘blind spots.’
Yup, just like when you’re driving. You check your mirrors, make sure you’re not going to hit anything, but sure enough, when you move…
I’ve got an idea!
Now, how does that idea actually become real and go together?
That’s what prototyping is for. So you can mess up a bunch, with minimal consequences, so that you can figure out how something, that doesn’t exist yet, and there’s no manual for, should function. As well as how it should be formed, and, well, while you’re at it, what color(s) it should be.
