We had a cat the used to go outside of the box before. The issue was, when she scratched and if even a little bit of litter was tossed outside of the box, the next time, she would see that little bit of litter, and just go on that. She didn't understand that it was wrong, because she was still going on litter. The only way to correct it was to constantly clean the area to make sure there was no litter around. We also got a big rubber mat for shoes with bermed edged and placed the whole litter box on it, so if she did go in front of it, at lease it would still be contained.

She was also a very long cat, and sometimes her butt would just stick out the end. This may have also been part of the reason she would go next to the box instead on in it. So I built her a larger box, and that worked. Even if your cat isn't that big, I'd try a larger box anyway in case it's a comfort thing.
