I once saw a nice colored chart showing how to do a pen test, sort of like a road map, if this port is open do that. I liked, but now I've forgotten where I saw it. It doesn't have to be colored or a map  , but if anyone had a checklist for pen testing that would be great.

Here's another helpful link to ISECOM's OSSTMM (Open Source Security Testing Methodology Manual):
