Explanation:

As Dr. Shetty is able to drive down the cost of complex medical procedures from $100,000 to $2,000 not by doing one big thing, but rather by doing a thousand small things. This approach focuses on driving down the cost of healthcare through process innovation. Process innovation is the mechanism when we implement a new or significantly improved manufacturing method with the help of a new technology in order to remain competitive and meet consumers demands at the same time. We try to solve an already existing issue or reforms an existed process in a different way to generate something with huge benefits, likewise, same is the case here with Dr. Shetty who has reduced the cost of healthcare quite significantly just by changing and improving his production methods.
