From MoreSteam: Fewer workers with fewer resources are trying to satisfy the increasing demand for products and services. That's a tricky equation to balance. An inevitable outcome of trying to balance that equation is multitasking. Everything still needs to get done, and in most cases, a sequence of operations or activities still needs to happen, so we begin a start/stop cycle of getting just enough done to move to the next step.
Multitasking is not doing two or more tasks at once; it's an attempt at rapid task-switching or serial-tasking. I probably don't need to talk much about the likely outcome. It's bad. But how bad is it?
