Is moving in with your girlfriend/boyfriend after just dating for a short period of time a good thing?

A friend of mine is going through that. She had been dating this guy for lets say maybe 9 or 10 months but she is unsure if she may wait just a bit more time to get to know the guy better in order to come up with that decision or jsut keep dating him as they had been doing so far.
