When the person performs as I envision they would. When you hire someone, you think they have the right skill sets and they are going to be a fit. When that actually happens and they surpass your expectations, that's a successful hire.

I hired somebody out of fear that I wouldn't be able to fill the position. I felt like I was already asking everybody in the office to do too much, and I was worried about the impact of work not getting done on everyone else. I felt I needed to fill the position quickly and I was concerned that I wouldn't be able to find another person to fill it. I didn't do my normal due diligence.
