"In the mid-1990s, Shetty began experimenting with a business school concept alternately called upskilling or task-shifting. The idea is for everyone involved in a complex process to work only at the top of his qualification, leaving simpler tasks to lower-paid workers. In a hospital, this might mean that the costliest staff—experienced surgeons—enter the operating theater only to complete the most difficult part of a procedure, leaving everything else to junior doctors or well-trained nurses. Then they move to the next theater to perform the same task again."
