Humans are not good at multitasking, despite what many will tell you. They end up doing a bunch of tasks poorly and really do lose their focus. We are not machines and therefore don’t have the ability to slice up the time in ways that will be the most productive. Computers are quite good at doing this, but humans are not. What suffers is our focus and the challenge to remain effective.
You may be able to get away with doing two items at the same time. But, remember, most tasks will require full attention and it is not possible to do them simultaneously. Even computers have to emulate multitasking when the number of tasks required of them is greater than the number of processors. However, they do everything in a completely programmatic way. So, they know how to handle the emulated multitasking.
Using Technology to help keep focus
If you can use computers to do multiple tasks, that can help you get more done in less time. However, you still will need to manage the time for those tasks to ensure it has all the inputs needed and take care of whatever outputs are produced.
Letting the mind wandering off really does kill your productivity and focus
Another problem humans have with multitasking is that we can’t help our minds wandering off when doing mundane tasks. We forget what we were doing. This often requires us to retrace our steps to figure out what we may have missed. It’s certainly possible to come up with a system where you write down where you left off, etc. But even here, the more tasks you try to do this with, the tougher it will be to manage.
The situation gets complicated when managers expect you to get multiple tasks done and they don’t seem to take into account the amount of time needed for all the tasks. If this is your situation, try to find ways to offload or delegate to others. You may be able to convince management to outsource aspects of your job to external resources. More companies are implementing this as it is quite cost effective. There are some challenges when doing this as you will need to manage those resources and deal with company trade secrets, etc. But, if you can make this work, it can be a tremendous productivity booster.
Your focus will improve if you can keep your tasks to one item at a time.
You may need to determine the critical paths of the tasks you are responsible for. When you show your manager that you get higher quality work complete by working on tasks one at a time, you should be able to convince him or her this is a better approach.
