This document discusses the differences between multitasking and task engagement. It explains that multitasking involves switching between tasks before completion and leads to delays, stress, and lower quality work. Task engagement means focusing completely on one task at a time until it is finished. The document outlines some of the personal and organizational costs of multitasking, as well as the benefits of task engagement like faster completion, higher quality work, and less stress. It argues that simply telling people to stop multitasking is not enough and that a transition requires awareness, prioritization of tasks, protection from interruptions, and experience of "flow".
