|Multi-tasking, efficient ??|
There are some questions being asked on the efficacy of multi-tasking. They are :
1. Do lean systems advocate multi-tasking or single tasking ?
2. Is multi-tasking effective in the long run ?
3. Are people who resort to multi-tasking more efficient than others ?
4. Does multi-tasking lead to better or worse output and quality ?
Though it is difficult to get answer to all of these questions through a classroom experiment, we can try to find whether multi-tasking does lead to longer processing times than single tasking. If indeed multi-tasking does take more time to complete tasks, what is the approximate percentage of this increase ?
A. Start the stop watch.
1. On the top left corner, name it A, write the digit 1 in words, One
2. Turn to bottom right, bring it to top left, name it B, and write Roman numeral of 1.
3. Turn the paper to the other side, behind the A side, write C and make one hash mark
4. Turn to the bottom right, bring it to top left, mark it D and draw a small five cornered star.
5. Repeat this for digit 2 on edge A, Roman numerals II on edge B, two hash marks on edge C and two star marks on edge D.
6. Repeat this till numerical 10.
Stop the Stop Watch . This is multi-tasking. Note the timing in seconds.
B. Start the stop watch.
1. finish writing the digits 1 to 10 in words on edge A
2. Go to edge B, write Roman numerals of numbers one to ten
3. Turn around, go to edge C, do hashes, progressively from one to 10 and
4. go to edge D, draw small five edge stars progressively from one to ten.
Stop the Stop Watch . Note the timing in seconds
1. Write down your observation in two or three sentences..
2. Find the average percentage improvement in time moving from multitasking to single tasking.
3. Is single tasking tasking efficient than multi-tasking, all the time ?? Comment ..
1. Single tasking any time is better than multi-tasking especially if the job is repetitive and time consuming.
2. When there are many jobs to be carried out, it is always better to complete them as single tasks than to attempt to complete them by multiple tasking. This improves quality of the output, reducing the time spent on rework or defects.
3. Multi-tasking is tiring and unless very carefully done, can cause errors in the job, resulting in poor quality and high rework or error correction costs.
