I'm working at a small company (less than 10 people), and I need to purchase some high end equipment I know nothing about..... Brings back memories from grad school. I've been here less than two weeks. In the past I educate myself on the equipment, and figure out what the relevant parameters are. But it always seemed like I was missing some relevant parameter(s). This whole situation makes me feel like an idiot! Does anyone else have this sort of situation? How do you go about dealing with it?
