Here's one example to illustrate the point. When a smoker takes a cigarette break, on one level he's simply seeking the nicotine his body craves. That's the functional dimension. But that's not all that's going on. He's hiring cigarettes for the emotional benefit of calming him down, relaxing him. And if he works in a typical office building, he's forced to go outside to a designated smoking area. But that choice is social, too--he can take a break from work and hang around with his buddies. From this perspective, people hire Facebook for many of the same reasons. They log onto Facebook during the middle of the workday to take a break from work, relax for a few minutes while thinking about other things, and convene around a virtual water cooler with far-flung friends. In some ways, Facebook is actually competing with cigarettes to be hired for the same Job to Be Done. Which the smoker chooses will depend on the circumstances of his struggle in that particular moment.
