In IT the problems are solvable. We can adopt systematic troubleshooting steps and most problems can be identified and resolved in minutes or a few hours. (Yes, I have problems that extended much longer—all IT professionals have—but those tend to be rare.) IT professionals have knowledge of the systems they manage, and they have resources (from online communities, colleagues, vendors, and even user manuals) to help them resolve unfamiliar problems. When their problems are solved, all users can recognize the green LED’s that signal functioning connections, operational computers, and—in schools—smiling teachers.
