To do real good physics work, you do need absolute solid lengths of time … it needs a lot of concentration … if you have a job administrating anythin… - Cal Newport

People play differently when they’re keeping score,” the 4DX authors explain. They then elaborate that when attempting to drive your team’s engagement toward your organization’s wildly important goal, it’s important that they have a public place to record and track their lead measures. This scoreboard creates a sense of competition that drives them to focus on these measures, even when other demands vie for their attention. It also provides a reinforcing source of motivation. Once the team notices their success with a lead measure, they become invested in perpetuating this performance.

I argue that his approach to batching helps explain this paradox. In particular, by consolidating his work into intense and uninterrupted pulses, he’s leveraging the following law of productivity: High-Quality Work Produced = (Time Spent) x (Intensity of Focus)

The relevant research literature also helps clarify this sense of overload. In their original 2004 study on attention fragmentation, Victor M. González and Gloria Mark partitioned the efforts of the employees they observed into distinct working spheres, each representing a different project or objective. They found that on average their subjects worked on ten different spheres per day, spending less than twelve minutes on one before switching to another.36 A follow-up study in 2005 found the observed employees touching on eleven to twelve different working spheres per day on average.37 The large number of different spheres these subjects tackled in a given day, combined with the reality that each sphere demands the accomplishment of many smaller tasks and presumably dozens of emails, provides a harried portrayal of modern knowledge work. “At night, I often wake in a panic about all the things I need to do or didn’t get done,” writes journalist Brigid Schulte in Overwhelmed, her 2014 book on this busyness epidemic. “I worry that I’ll face my death and realize that my life got lost in this frantic flotsam of daily stuff.”38
