Thank you 

I understand you choice. Work usually get done quicker when there is someone to compete with. And when actors work separately, we don't have to "coordinate" (match up steps like in dancing) ;-)

There are people who may not like to buy another set of buckets, cutting board and knife. And in competitive settings, there may be higher risk of accidents and lower quality of output -- some competitors may "cut corners" (to win).

In a business setting, the choice may be based on "cost" and the number of kaffir limes to be clean-and-cut. At times, one actor would be hired and the other turned away (to collect wild veggies to feed the family).

Now let pretend that kaffir limes are a day of patients waiting to be 'clean-and-healed'. and we have several nurses and doctors available for this process. How would we 'design' this process, if cost is also an objective, as well as patients' satisfaction and actors' satisfaction?

[Hey, no prize for correct answers from me. But your hospital general manager will you forever and two more days ;-)
