In an article for Inc., Geoffrey James uses three years of data from a smartphone app called Track Your Happiness, which allows users to report their feelings in real time, to arrive at a curious conclusion. The app data suggests people are most content whenever they are just really concentrated on a particular task, regardless of what the task is. Thus, James finds, “In other words, employees aren’t more productive when they’re happy. They’re happy when they’re focused, which can make them more productive as an accidental byproduct” (emphasis original).
Along this line of reasoning, offering a game lounge for employees may not grant that productivity boost the business wants. It could mean instead that simply satisfying some basic work conditions is still the best way to get more productivity: dispensing neither too much nor too little work to employees, removing distractions, and implementing robust work-life balance policies.
