People and organizations in clock-time culturesare more likely to emphasize monochronic (M-time) approaches, meaning they like to focuson one activity at a time. People in event time cultures, on the other hand, tend to emphasizepolychronic (P-time) approaches, meaning they prefer to do several things at once.
I think that going by M-time keeps things organized and on track. Not saying that P-time can't be beneficial, but it's kind of hard to have a level head to focus on something if you're multitasking because your brain tends to move in different directions which can start to make things confusing. By completing activities from start to finish before moving on to the next can keep an individual focused and able to think through things thoroughly. I personally take the M-time approach throughout my daily routines.
