I have written another essay in the same topics, hoping I can have as many critics as possible.
Everyone has more and more to do each day. Workload is generally increasing and time seems getting shorter. Therefore, some people try to perform many tasks simultaneously. But to which extend this solution is possible and efficient? Although an accurate answer to this question would depend on the tasks at issue, but I believe that assessing one task at time is better than multitasking.
Of course, there is no big issue listening to music, ironing clothes and having a discussion with a friend. But when it comes to serious tasks that require concentration, such as writing an essay, analyzing a graphic or writing a code for a new IT program, multitasking becomes a serious source of error or at least results in a bad performance. For this kind of work to be done, all sources of distraction should be absent in order to fulfill the task correctly. Human is created with one brain, and in order to have an optimal function, this brain should not be used for several task at the same time.
In the same way, even computer with one processor cannot make an addition and a multiplication in the same time. In the conception of operational system, there is a clear concept that illustrates that; when many tasks arrive to the processor in the same time, they have to wait until the currently performed task finish in order to be able to enter the processor. This issue is now overcame using multiprocessors, but humans are mono brain creature and are consequently unable to perform many critical tasks at the same time.
From my experience, when I am in a situation in which I have for example to talk to someone while I am writing something, it often happens that I start writing what I am supposed to say or I say what I am supposed to write. Such interferences are clearly sources of error that I can avoid only by concentrating on one task a time.
In this context, organization and priority become key elements in order to perform many tasks. When I find myself in situation where I have to deal with many tasks, I take a brief time to order these tasks by priority and then I start by the most important.
To sum up, I would have liked to be able to assess many tasks at the same time, but it has been proven that multitasking is a potential source of error. Instead, organization and priority should be adopted when dealing with different tasks.
