I needed almost all of these just to survive...
in a non-profit organization! Because I was the only tech in the west half of the state, I had to go it alone, and became very independent. I needed all those skills to keep the network and infrastructure going. I say I'm weak on project skills, but to tell the truth, every time we opened a new office or revamped the network at an existing location, it was quite a project. I usually did all the construction myself, but needed the business sense, to realize when it was actually cheaper to hire a contractor to finish a job, or build a PBX.
