Here is my checklist. 1. Compile a decent on-boarding checklist. This is best done during your own on-boarding as you go through the steps yourself. I usually just drop it in a text file and worry about formatting later. And even then most I would do is wiki/markdown. 2. Pick a suitable initial task, which is trivial enough to not throw the subject in confusion mode, but still spanning through enough of the codebase/product, as it is supposed to verify how accurately the checklist from step one was compiled and executed. 3. Be around to assist at any times and stress your availability - on-boarding someone is work and it won't do itself.
