In this part . . .
People say that life is what happens to you while you're making other plans. That saying has a rough equivalent in work: "Your real job is never the same as the job described in the job description." New and unexpected experiences always cause change.
Part IV prepares you for three of the unscheduled, not-on-the-menu tasks of modern technical work. For example, you may be a great carpenter and a whiz at residential and commercial construction, but as you rise in the company, you may find yourself required to make presentations to clients. That's where the charts and graphs in Chapter 17 come in. Or perhaps you were hired to cut 2 × 4s, but now you're a supervisor who needs to check employee time cards and bill labor to clients. Never fear: Chapter 18's discussions of time math are here to help. And heaven help you if you have to buy the computers for the front office! Heaven may help eventually, but in the meantime, take a look at Chapter 19. It describes computer capacities and speeds.
