Business development is everything, especially if you believe the old executive adage that "if you are not growing, you are dying." You need to grow your field service business, no matter what area of field service you work in (plumbing, AC repair, machine maintenance, and so on.) For years and years, the idea of business development was predominantly external. You needed better talent (hiring). There were factories and equipment to be bought. The technology was not there yet. Scaling and becoming profitable were about defeating the challenges out in the marketplace.It is a very different picture around business development these days.
