There are all types of people who are engineers. I have worked with some very competent in the field type guy's who also were electrical engineer's. Some make for excellent project manager's, particularly on large system integration projects. Not only do these systems require extensive installation expertise, but also the ability to manage a lot of capital expense, and employee's. It seem's to me that the best engineers are people who have that natural ability to tackle all parts of the engineering from the design,thru the field and also the money management end.
