Multitasking entails juggling different work activities and shifting attention from one task to another. Basically, the human brain gives permission to do a particular activity at a time. But when we practice any activities multiple times it becomes a habit. When we perform any task that is our general habit, it will not require taking serious permission from the brain all the times. For ex., we breathe continuously and it never interrupts for any other task or activity. Because those are our most practiced habits.
Similarly, when we switch between multiple activities, those are very much familiar to us, very fast is called multitasking. We need to make a habit before we juggle between different work activities.
In any organization, this is very much essential to becoming a multitasking leader or member to keep the team or organization in the industry race. The market is very much competitive and expense is also very high. So, an organization should always try to involve multitasking person in the team and management as much as possible to achieve the company goal. Focusing only on one task could equate to lower productivity levels which most organizations regard as unacceptable.
