When to resign?

[Kevin]

Look around your own organization for some precedent. If you know someone who gave their notice a full two months in advance and the company allowed them to assist in transitioning to someone else over those two months, then maybe that's the best way to leave things. It also depends exactly what you do. If you have some sort of executive job where you have a million irons in the fire, you might want to give notice sooner rather than later. If you have a job where you could train someone up in two weeks to adequately replace you, that's something to consider also.
