When it comes to IT operations, multitasking seems to be a prerequisite. Quite often it's even written into the job posting. However, research is revealing that multitasking may do more damage than good.
Between the time-driven customer responses, the growing demands for technology projects from the business, 99.999 up-time guarantees for the system, and a multitude of maintenance needs for the entire environment, your in-house IT resources have their days filled with continual distractions. It's understandable that IT leadership is on a lookout for women and men in capes with a big "M" for Multitasking emblazoned across their shirts. But it turns out, these multitasking superheroes may not really exist.
Workplace evidence, cognitive studies and our personal anecdotes, at best case, point towards multitasking being a myth, and at worst, show that multitasking affect our health and professional lives in some negative ways.
This conclusion is highlighted by the following five reasons:
A cognitive study by the University of Utah found only 2% of the population can multitask effectively. The rest of us are not very effective. However, more than 50% of the population believe they are very effective.
Several studies have found Multitasking (primarily task switching) can be 40% less productive then batching similar tasks. Similar to a machine there are time and costs to change over from one task to another.
The error rate for someone performing many tasks in a task switching environment compared to one with much fewer switches is much higher. Task switching especially when it may not be planned such as in IT support are disruptive and errors are higher in a disruptive environment.
In a study of two groups performing the same tasks with and without task switching the heart rate was higher among the task switching group. The constant switching can provide a feeling of lack of control and lack of accomplishment. Both can be stressful.
If the first 4 reasons alone don't make you unhappy then you may be someone prone to crave multi-tasking. You may value being busy over being productive. You may believe you are part of the 2 %. Or you may have trouble focusing, so you welcome distractions to get out of having to focus. Bottom line, you probably still fall prey to being less productive then you can be and creating a less healthy work environment for you or your team.
